Cranial Osteoma treatment, do you have to shave your whole head?


I have a cranial osteoma that probly has a subdural portion that will have to be removed with neurosurgery. Will i have to shave my whole head or just the part they have to cut into it at?
I have hair almost to by waist it will be so sad to cut it all
----------

they will probably decide that, however when my sister had emergency surgery they shaved only that portion where they went in at, but a nurse came and shave the rest so that it would all be even!, hope that help!  (+ info)

Radio Frequency Ablation of An Osteoid Osteoma?


An Osteoid Osteoma is basically a benign bone tumor yet causes tremendous pain due to inflammation. One of the means of removing this tumor is through Radio Frequency Ablation (RFA). Basically this bone tumor is cooked off the bone using radio frequency. My question is where does the bits of the bone go? I would assume that it is excreted through the urine, but I am not sure. If this is true, could the bits of bone (though microscopic) going through the kidneys cause kidney stones?

Any help would be much appreciated.

Can Osteoid Osteoma be cancerous ?


I had an x-ray done 2 days ago.I was diagnosed with osteoid osteoma. A tumor in my shin bone. Now the doctor basically said it "shouldn't" be cancerous, and that we would need an MRI to know for sure.Now im scheduled for one in 4 days,and im just wondering if it can really be cancerous.Since the doctor and my dad ( also a doctor ) kept the matter kind of quiet and didn't say much and i would like to know. I'm 15 by the way.

There is no way to know if this tumor is benign or malignant without a biopsy. Your doctor is relying on what is considered 'the most common' approach . . that cancer is rare in 15 year olds and that the body can have benign tumors in this location. Further testing is warranted because no one is 100 percent sure . . the MRI will give them a bit more information and the doctor figures he can go from there . . if the MRI indicates further testing they may decide to remove the tumor and do a biopsy at that time. The problem with this approach is that if this turns out to be a malignancy like osteosarcoma or Ewings sarcoma than only a sarcoma specialist should be doing this surgery. If your father is a doctor he should have known all this . .but if he doesn't than you need to speak up. This is your life and your leg. But first things first . . go for the MRI and see what the results are before jumping to conclusions.

And, you need to open up a dialogue with your father and let him know that you need the truth at all times. Hopefully this will turn out to be a benign osteoid osteoma that can easily be removed. Good luck.

I would like to hear from anyone who has knowledge of the rare skin disorder, osteoma cutis. And treatments.?


Osteoma cutis is little bits of calcium deposits under the skin (mine is where I had acne when I was younger.) I had dermabrasion many years ago, but the condition recurred because of the time it took for healing...it forms in scar tissue.

INTRODUCTION Section 2 of 9
Author Information Introduction Clinical Differentials Workup Treatment Follow-up Pictures Bibliography



Background: Strictly defined, osteoma cutis refers to the presence of bone within the skin in the absence of a preexisting or associated lesion, as opposed to secondary types of cutaneous ossification that occur by metaplastic reaction to inflammatory, traumatic, and neoplastic processes.


Pathophysiology: Bone arises in skin and soft tissues through mesenchymal (membranous) ossification without cartilage precursors or models (enchondral ossification, as in the skeletal system).

The lesions of osteoma cutis differ from tumoral calcinosis in that they represent bone formation, and calcinosis refers to calcium salt deposits.

In addition to colonic polyposis, epidermal cysts of the face and the scalp, and multiple fibromas, osteomatosis in the form of intraosseous (not cutaneous) osteomas may develop within the membranous bones of the head in Gardner syndrome.


Frequency:


In the US: Although said to be rare, with no well-defined data on the incidence, a plethora of conditions and syndromes may be found in association with osteoma cutis, and the frequency of its occurrence varies accordingly. Primary lesions with no underlying cause are even more rare, but they account for approximately 20% of all cases.
Mortality/Morbidity: Osteoma cutis is not life threatening, although local discomfort and/or disfigurement may lead the patient to seek consultation.

Race: No race is predisposed to develop osteoma cutis.

Sex: Generally, no distinct sexual predominance exists. However, one cause of osteoma cutis, Albright hereditary osteodystrophy, occurs with a female-to-male ratio of 2:1.

Age: Osteoma cutis may occur at any age.

History:

Patients may report having hard areas in the skin.
A familial occurrence of Albright hereditary osteodystrophy may be present.
Physical:

The presentations of osteoma cutis can be highly variable, with clinical entities that are defined by the number, the form, and the location of the lesions.
Osteomas may present as single or multiple, extremely hard nodules, plaques, or miliary tumors.
The face, the extremities, the scalp, the digits, and the subungual regions are the most commonly affected sites.
Causes: Osteoma cutis is a feature in several groups of patients.

Albright hereditary osteodystrophy, which includes most patients with pseudohypoparathyroidism and pseudopseudohypoparathyroidism, is due to an autosomal dominant defect in the alpha subunit of intracellular guanyl nucleotide-binding protein (G protein).
The characteristic phenotype includes short stature, a round face, defective teeth, mental retardation, brachydactyly, and osteomas of the soft tissue and the skin.
Tetany is often the presenting sign of pseudohypoparathyroidism, formerly called Albright hereditary osteodystrophy. In addition to skeletal system abnormalities, lesions of osteoma cutis are frequently observed.
Single, small osteomas, arising later in life, sometimes with transepidermal elimination of bony fragments may be a cause.
Multiple, miliary osteomas of the face, following acne, neurotic excoriation, or dermabrasion is a possible cause.
Congenital plaquelike osteomatosis or limited dermal ossification is generally present from birth; the skin of the scalp or the extremities is often affected.
Fibrodysplasia ossificans heteroplasia and fibrodysplasia ossificans progressiva are possible causes.
Miscellaneous rare disorders with or without cartilaginous elements include osteomas of the distal extremities and multiple osteomas of childhood unrelated to Albright hereditary osteodystrophy.

Lab Studies:


Serum calcium and parathyroid hormone (PTH) levels help to define Albright hereditary osteodystrophy.
Imaging Studies:


Plain radiographs demonstrate lesions but are not necessary for diagnosis.
Procedures:


Excisional biopsy for diagnosis, relief of discomfort, or cosmesis may be performed.
Histologic Findings: Small spicules to large masses of mature bone are found in the dermis or extend into the subcutaneous tissue. Spicules of bone may enclose areas of mature fat, recapitulating a medullary cavity, but hematopoietic elements are seldom observed (see Image 3).
TREATMENT Section 6 of 9
Author Information Introduction Clinical Differentials Workup Treatment Follow-up Pictures Bibliography




Medical Care:

Removal by excision or laser resurfacing to unroof overlying skin may be performed. Treatment with the Er:YAG laser may result in less hypopigmentation and scarring than with the carbon dioxide laser.
Other reported treatments with unproven efficacy include the following:
Topical application of tretinoin to provoke transepidermal elimination
Etidronate disodium taken orally
Consultations: When several lesions are noted, especially in pediatric patients, evaluation for associated syndromes may be warranted. FOLLOW-UP Section 7 of 9

Can anyone tell me about Osteoma's?


A small hard lump appeared on the bone behind my ear about a week ago, the doc says its an osteoma, and has referred me to orthopaedics. Has anyone else had one?
----------

Osteoma is a benign bony outgrowth of membranous bones. They are found mostly on skull and facial bones. Large osteomas may develop on the clavicle, pelvis, and tubular bones (parosteal osteomas). Soft tissue osteomas may occur in the head, eye,and tongue,or in the extremities. Osteomas are slow growing lesions that are normally completely asymptomatic. They only present if their location within the head and neck region is causing problems with breathing, vision, or hearing.

The highest incidence is in the sixth decade. Some authors report that osteomas occur more often in women than men (3:1). Multiple osteomas are associated with Gardner's syndrome. The etiology of osteomas is unclear. They may be related to osteoblastomas or may simply be a developmental anomaly. The fact they are often found in the auditory canals of swimmers and divers who frequent cold water suggests that in some cases they are some type of inflammatory reaction.

The radiological appearance of osteomas depends on their location. Central osteomas are well delineated sclerotic lesions with smooth borders, without surface irregularities or satellite lesions. Dr. Enneking describes the lesion as having the appearance of "one-half of a billiard ball" attached to the underlying bone. The adjacent cortex is not involved or weakened. Peripheral osteomas are radiopaque lesions with expansive borders that may be sessile or pedunculated. Osteomas need to be differentiated from enostosis which also appear as densely sclerotic well-defined lesions on x-ray.

Bone scan will show increased uptake during the active phase of growth, which will diminish to background levels as the lesion becomes progressively less active.

There are two types of osteomas microscopically. Compact or "ivory" osteomas are made of mature lamellar bone. They have no Haversian canals and no fibrous component. Trabecular osteomas are composed of cancellous trabecular bone with marrow surrounded by a cortical bone margin. Trabecular osteomas can be found centrally (endosteal) or peripherally (subperiosteal).

Treatment of osteomas is only necessary if they are symptomatic. Large osteomas should be evaluated to rule out other diagnoses. '

Osteoid Osteoma?


I was dx with an osteoid osteoma last July. I have had the osteoma for at least 4 years. I have read things on the internet that say they usually resolve within 33 months but mine has not. It is painful, mostly at night, and aspirin helps. But, anytime it is touched or bumped it causes severe pain, and I work with kids all day so it gets bumped a lot. It is on the front of my lower leg--I think this bone is called the tibia. My questions are: has anyone had this and did it resolve on its own? How do I deal with the pain--is there some type of protective cover to keep it from being hit? Can and how is it removed surgically? Any other info is appreciated.

osteoid osteoma?


my brother's dr. thinks he might have osteoid osteoma, but there isn't alot of info. online because it's so rare, can anyone give me the basic information on it?
----------

Osteoid osteomas are benign bone neoplasms, occuring usually in the adolescent years, causing pain, often at night, usually relieved by anti-inflammatory drugs.

They are not difficult to diagnosis, though lesions in the neck of the femur and spine can be difficult. A combination of plain radiographs, MRI and thin-section, high-resolution CT, is usually enough.

Though surgery is the standard method of treatment, there is considerable morbidity. For some years now, radiofrequency thermal ablation (RFA) has been used to ablate (cook) these lesions, with considerable success and minimal morbidity.

Hope this info helps!  (+ info)

Choroidal Osteoma????


My daughter is 18 and was just told that she may have an choroidal osteoma in her left eye. This is a very rare condition. She is scared & so am I. Please no mean comments.Is there anyone out there who has this condition or has heard of it??
Thanks so much!
----------

That certainly is not a happy diagnoses. I hope it turns out to be something else. This is the best definition I have of Chorodial Osteoma. I hope it helps, remember it is information only. Your doctor is the best person to give you the answers YOU need. Take care. :)

Choroidal osteoma is characterized by bone in the choroidal vascular layer of the eye. These bone deposits are more likely to be found near to the optic nerve.

When your eye care professional looks into your eye, a typical choroidal osteoma will appear like a yellow subretinal tumor near the optic nerve. Pigment can be seen to dust its surface. The choroidal osteoma typically has well defined scalloped edges. Hemorrhage near the edge of a choroidal osteoma suggests the presence of subretinal neovascularization.

Photography is used to document the choroidal osteoma size and shape. Baseline photographs are helpful for subsequent evaluations for growth and neovascularization.

Fluorescein angiography: Since a choroidal osteoma is made of bone, when fluorescein dye circulates through the eye, it will be slow to penetrate the tumor. Once the fluorescein dye is inside the choroidal osteoma, it also has trouble getting out. This is why the fluorescein pattern of choroidal osteoma is one of slow uptake and persistent "late" fluorescence.

Ultrasound: Ultrasound examination of an eye with a choroidal osteoma will demonstrate intense reflectivity from the tumor and shadowing of the posterior orbital contents. If the intensity (gain) of the ultrasound machine is decreased, the eye-care specialist is likely to see persistent reflectivity or “brightness” from the tumor. Ultrasound can also be used to measure the thickness of a choroidal osteoma.

Computed radiographic imaging: Computed axial tomography (CT) can be particularly helpful to see the calcification of a choroidal osteoma in unusual cases.  (+ info)

questions about Osteoid Osteoma ?


The Doctor said that there is Osteoid Osteoma in my knee near the Cartilage area and he can't operate there.

He said to use crutches and take naproxen, unitl it goes away and does not recommended surgery.

My questions:
How Long does it take for the tumor to go away?? ( like 2-3 years?)
How would crutches actually help with the pain?
Would doing exercises or sport activities make the pain go worse?
How is operating near a cartilage dangerous? Can't he use Radiofrequency ablation to heat it?


Plz, help me out here with any info. I don't have knowledge about the inner working of the knee.
I really appreciate it.
----------

These are things you should have asked the doctor.
Get a second opinion and this time ask questions.  (+ info)
