1/1223. Solitary hepatic hemangioma in a newborn infant complicated by cardiac failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. Case report and review of the literature.A newborn infant with a large hepatic hemangioma developed congestive heart failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. The patient was mildly heparinized (250 units per kg and day) and underwent successful resection of the tumor without lobectomy at the age of 3 days. blood volume increased from 93.9 ml/kg at the age of 5 h to 124.2 ml/kg prior to surgery. Red-cell mass simultaneously decreased from 53.8 to 39.4 ml/kg. The increase of blood volume is explained by congestive heart failure, the decrease of red-cell mass by intravascular coagulation within the tumor resulting in formation of thrombi and microangiopathic hemolytic anemia. A review of the literature on infants with symptoms caused by an intrahepatic hemangioma during the first month of life confirms that surgical intervention is the treatment of choice for infants with giant solitary hemangioma of the liver.- - - - - - - - - - ranking = 1keywords = hemangioma (Clic here for more details about this article) |
2/1223. The rebound effect in the treatment of complex hemangioma with interferon alpha 2A.The authors report the case of an infant with an extensive face hemangioma with subglottic airway obstruction which had been successfully treated with interferon alpha 2A but then reoccurred with the same dimensions and airway blockage after treatment was abruptly interrupted. The authors suggest the implementation of a standard procedure for the interruption of interferon alpha 2A treatment in order to avoid this rebound effect and advise on the need for further studies to properly evaluate dosage and administration parameters for interferon alpha 2A in the treatment of difficult hemangioma.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma (Clic here for more details about this article) |
3/1223. Successful treatment of obstructive sleep apnea with use of nasal continuous positive airway pressure in three patients with mucosal hemangiomas of the oral cavity.cysts and benign tumors are uncommon causes of obstructive sleep apnea (OSA), and surgical removal is usually favored. In patients in whom an operation poses a high risk, however, nasal continuous positive airway pressure (CPAP) may prove beneficial. We describe three patients with hemangiomas of the oral cavity in whom polysomnography revealed moderate to severe OSA. In all three patients, nasal CPAP effectively decreased sleep-related disordered breathing events and dramatically improved their sleep. To our knowledge, this is the first report of OSA associated with hemangiomas involving the upper airway. Our experience suggests that nasal CPAP therapy is effective and well tolerated in such patients.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma (Clic here for more details about this article) |
4/1223. Complex right hemisphere developmental venous anomaly associated with multiple facial hemangiomas. Case report.Complex developmental venous anomalies (DVAs) represent variations of normal cerebral venous drainage and consist of dilation of the superficial and/or deep venous system. These rare anomalies can occur unilaterally or bilaterally, supratentorially or infratentorially, focally or they can affect the entire hemisphere. Some DVAs are associated with cervicofacial venous malformations or facial lymphatic malformations. Anomalies of this type are generally clinically silent, and cerebral dysfunction is usually absent. Symptoms, when they occur, are most commonly headache or mild seizure disorders. The angiographic findings are striking, with well-formed but enlarged transcerebral medullary and deep and/or superficial cortical veins. Opacification of these venous structures occurs within the same time frame as a normal angiographic venous phase. The authors report the case of a 33-year-old man in whom a large inoperable arteriovenous malformation had been previously diagnosed and who presented with seizures. Repeated magnetic resonance imaging and angiography demonstrated abnormally dilated transcerebral, superficial, and deep venous structures involving the entire right hemisphere with no identifiable nidus. Additionally, multiple bilateral benign facial hemangiomas were present in this patient. It is important to recognize this rare venous appearance as a developmental variant and not mistake it for an arteriovenous malformation or a partially thrombosed vein of Galen malformation. Because these venous anomalies are extreme variants of the normal venous system, hemorrhage rarely, if ever, occurs and the patient can be reassured that no interventional or surgical therapy is necessary or warranted.- - - - - - - - - - ranking = 0.71428571428571keywords = hemangioma (Clic here for more details about this article) |
5/1223. Clinical experience with presumed hemangioma of the choroid: radioactive phosphorus uptake studies as an aid in differential diagnosis.A total of 27 cases of choroidal hemangioma was evaluated with radioactive phosphorus uptake studies. In each case the diagnosis of malignant melanoma was initially entertained, but the 32P test was unequivocally negative in every instance. follow-up studies in every case have supported the clinical diagnosis. In 22 patients, the lesion was treated with photocoagulation, and in every treated case the serous macular detachment disappeared. The importance of early and correct clinical diagnosis is stressed, since these are salvageable and potentially useful seeing eyes.- - - - - - - - - - ranking = 0.71428571428571keywords = hemangioma (Clic here for more details about this article) |
6/1223. A unique cause of unconscious urinary incontinence.The authors present a case of a healthy 55-year-old woman with a 1-year history of vaginal malodor and perineal dampness. A pyridium (phenazopyridine) pad test revealed a well-defined stain area no greater than 3 cm. Cystoscopic examination revealed multiple multilobulated polypoid neoplasms, which we feel probably represent pedunculated hemangiomas. Removal of the neoplasms cured the dampness, malodor and recurrent vaginal infections. We submit this case as a unique cause of extraurethral incontinence.- - - - - - - - - - ranking = 0.14285714285714keywords = hemangioma (Clic here for more details about this article) |
7/1223. Transpupillary thermotherapy in the management of circumscribed choroidal hemangioma.PURPOSE: To report a case of circumscribed choroidal hemangioma effectively managed with transpupillary thermotherapy. METHOD: A 53-year-old man affected by extramacular circumscribed choroidal hemangioma had sustained a decline in visual acuity caused by subretinal fluid exudation into the macular area. Multiple attempts at treatment with scatter photocoagulation over the surface of the lesion for several years had been unsuccessful in reducing tumor-related exudation. The patient was examined on referral and underwent a single session of treatment employing transpupillary thermotherapy. The course of the lesion after treatment was documented with fundus photography and ultrasonography. RESULT: Complete atrophy of the choroidal hemangioma with resorption of subretinal fluid was documented over the 6 months after transpupillary thermotherapy, with improvement in visual acuity. CONCLUSION: Transpupillary thermotherapy is an effective alternative to conventional scatter photocoagulation or radiation therapy for precise ablation of circumscribed choroidal hemangioma.- - - - - - - - - - ranking = 1.1428571428571keywords = hemangioma (Clic here for more details about this article) |
8/1223. Hemorrhagic epithelioid and spindle cell hemangioma: a newly recognized, unique vascular tumor of bone.BACKGROUND: Epithelioid vascular tumors of bone are uncommon and include epithelioid hemangioma, epithelioid hemangioendothelioma, and epithelioid angiosarcoma. It is important to distinguish among them because they have significantly different biologic potential and require different forms of therapy. In the current study the authors describe six cases of a distinct benign epithelioid and spindle cell vascular tumor of bone that, because of their unusual morphology, were confused with aggressive vascular neoplasms. methods: Cases were retrieved from the surgical pathology files of the Department of pathology or from the consultation files of one of the authors. hematoxylin and eosin stained slides were examined. immunohistochemistry was performed on two cases and electron microscopy was performed on one case. RESULTS: The tumors arose in the small bones of the hands and feet and the tibia. Three patients had multifocal bone disease at the time of presentation. Histologically, all lesions were comprised of lobules of spindle cells that grew focally in a fascicular pattern and were associated with abundant hemorrhage. Plump epithelioid cells were intermixed and were present focally in the interlobular areas as well, in which they lined larger, more well developed vascular spaces, often protruding into the vascular lumen in a "tombstone" fashion. Immunohistochemically and ultrastructurally the neoplastic cells had features of endothelium. One case was treated by amputation, one by resection, three by curettage, and one by curettage plus radiation therapy. None of the lesions was locally aggressive nor did any metastasize. CONCLUSIONS: The authors believe that hemorrhagic epithelioid and spindle cell hemangioma of bone is a histologically benign bone tumor. It should be distinguished from malignant epithelioid vascular tumors of bone, which have metastatic potential and need to be treated more aggressively.- - - - - - - - - - ranking = 0.85714285714286keywords = hemangioma (Clic here for more details about this article) |
9/1223. A case of perirenal hemangioma mimicking renal cell carcinoma.PURPOSE: We present a rare case of perirenal hemangioma that was detected incidentally. methods/RESULTS: Radiographic examinations revealed a 3.5 cm mass at the left renal hilum adjacent to the left renal parenchyma, which was difficult to differentially diagnose from renal cell carcinoma. Tumor resection was performed successfully. CONCLUSIONS: There was no recurrence observed 14 months after surgery.- - - - - - - - - - ranking = 0.71428571428571keywords = hemangioma (Clic here for more details about this article) |
10/1223. Removal of orbital apex hemangioma using new transorbital craniotomy through suprabrow approach.PURPOSE: To describe a technique combining the expertise of the oculoplastic orbital surgeon and the neurosurgeon which allows access to the posterior orbit, anterior fossa, cavernous sinus and suprasellar region with minimal brain manipulation. methods: A transorbital craniotomy through a suprabrow incision is performed removing part of the frontal bone and orbital roof as a single piece. This allows wide access with only minimal, if any, brain retraction. The superior, lateral and medial orbit is clearly visualized, as well as the apex of the orbit. The bone flap is replaced at the end of the case with tantalum plates. RESULTS: A cavernous hemangioma at the orbital apex was removed without complications. The exposure was superb and allowed identification and preservation of orbital structures. CONCLUSIONS: Transorbital craniotomy allows for wide access to the posterior orbit and parasellar region and anterior fossa of the brain with minimal brain manipulation. The use of a suprabrow incision results in an excellent cosmetic result. There is minimal postoperative morbidity, which decreases hospitalization time.- - - - - - - - - - ranking = 0.71428571428571keywords = hemangioma (Clic here for more details about this article) |
