1/176. Auricular endochondral pseudocysts: diagnosis and management.The auricle can be the site of a variety of cystic lesions, many of which involve either potential spaces between the auricular cartilage and the perichondrium or spaces within the skin and subcutaneous tissues. An auricular endochondral pseudocyst is a fluid collection located within the cartilaginous structure of the auricle. The auricular hematoma and the auricular pseudocyst may represent opposing ends of a continuum of damage and repair of traumatic insults. Whereas the hematoma represents a significant acute traumatic event resulting in cleavage between the perichondrium and the cartilage, the pseudocyst could be the outcome of chronic lower grade trauma. In this instance, the perichondrium not only separates from the cartilage but may be induced to regenerate an outer cartilaginous wall exacting the contour of the separated perichondrium, thus completing a cartilaginous auricular pseudocyst. This firm, cartilaginous outer cyst wall accounts for the increased difficulty in treating pseudocysts and clearly requires a different surgical treatment than for the hematoma. Having reviewed a substantial number of case reports, we recommend incision and drainage of the cavity followed by obliteration of the cavity by curettage, sclerosing agent, and pressure dressing. More invasive techniques should be reserved for an uncommon recurrence after adequate initial treatment.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/176. Inflammatory cysts of the pelvic peritoneum.Three young women with abdominal distension due to pelvic masses were investigated using ultrasound and conventional radiographic techniques. While the latter revealed masses of soft tissue density arising from the pelvis and displacing bowel, the sonogram indicated the morphologic features of thin-walled multiloculated cysts. They were located entirely within the peritoneal cavity and contained serous to serosanguineous fluid. The mesholelial lined walls were infiltrated with chronic inflammatory cells and were adherent to chronically inflamed fallopian tubes. Although these acquired cysts are familiar to pathologists and gynecologists, the literature contains little information about them.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
3/176. Radiologic differential diagnosis. Radiologic pattern: solitary cavity.The differential diagnosis of a left lower lobe cavity in this young patient with a history of productive cough should include hiatal hernia, pulmonary abscess, bronchiectatic cyst and bronchopulmonary sequestration. Hiatal hernia should be ruled out by barium swallow; acute pulmonary abscess by the lack of a history suggestive of a necrotizing pneumonia; bronchiectasis by bronchogram; and intralobar bronchopulmonary sequestration should be confirmed by aortography.- - - - - - - - - - ranking = 2.5keywords = cavity (Clic here for more details about this article) |
4/176. Heterotopic oral gastrointestinal cyst: report of 2 cases and review of the literature.Oral heterotopic gastrointestinal cyst is a rare entity occurring in infants and children and showing a predilection for males. The cyst usually appears as an asymptomatic swelling in the floor of the mouth. Difficulty in feeding, swallowing, respiration, and speech have been reported in approximately 30% of those affected. The tongue-in particular, its anterior aspectis involved in up to 60% of reported cases. The clinical, radiographic, and histopathologic features of cases of heterotopic gastrointestinal cyst involving the anterior tongue in a 2-year-old girl and the anterior floor of the mouth in a 2-month-old boy are presented, and theories of pathogenesis are discussed.- - - - - - - - - - ranking = 0.083737793571433keywords = mouth (Clic here for more details about this article) |
5/176. Perforation of multiple gastric duplication cysts: diagnosis by sonography.A case of perforation of multiple gastric duplication cysts is presented. The rarity of this case is based on its multiplicity, its small size, its perforation into peritoneal cavity, as well as on the detection of tiny foci of ectopic pancreatic tissue at the site of perforation. The sonographic appearance and the clinical manifestations are discussed.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |

7/176. optic nerve coloboma with retinal degeneration associated with cystic microphthalmia of the other eye.In a seventy-five-year old man an optic nerve coloboma with generalised retinal degeneration associated with a cystic microphthalmia of the other eye is described. The MR imaging revealed the existence of a left microphthalmic eye with a lower lid cyst. From the other eye an optic nerve coloboma with a cystic ectasia of the coloboma area freely open to the vitreous cavity was apparent. The ERG recorded from this eye was extinguished.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
8/176. Ectopic lacrimal gland cyst of the orbit.Lacrimal duct cysts are not common. It is extremely rare when a lacrimal duct cyst and an ectopic lacrimal gland develop in the orbital cavity. A unique case of an ectopic lacrimal gland cyst of the orbit is presented. A 33-year-old man had a palpable mass above the inferior medial orbital rim for nearly two years. An ocular examination was normal except for a movable, firm mass found in the anterior nasal inferior orbit of the right eye. An echogram revealed a homogeneous, hypoechoic cystic mass. Computed tomography of the orbit showed a well-encapsulated lesion in the lower orbit of the right eye near the inferior rectus muscle, without bony erosion. A tense, thin-walled, clear fluid-filled cyst measuring 15 x 12 x 13 mm in size was completely enucleated without rupture by anterior orbitotomy. Pathologic examination disclosed a small nest of normal gland tissue surrounded by a cystic lesion lined with two layers of lacrimal duct epithelium cells. No recurrent signs were noticed during a 12-month period of follow-up.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
9/176. Transperitoneal drainage for a large cystic degeneration after regression of an intra-abdominal desmoid tumor.A new technique is described for treating a large cystic degeneration after regression of an intra-abdominal desmoid tumors in patients with familial adenomatous polyposis. A cysto-peritoneal shunt is made for the relief of large cystic degeneration by creating a channel between the mesenteric cyst and the peritoneal cavity by means of a silicone tube to facilitate transperitoneal drainage.- - - - - - - - - - ranking = 0.5keywords = cavity (Clic here for more details about this article) |
10/176. "Pseudocyst of the auricle", othematoma and otoseroma: three faces of the same coin?Cystic swellings of the choncha of the ear without serious inflammation are routine findings for otolaryngologists. They are frequently diagnosed as othematoma or otoseroma and may be caused by traceable traumas or microtraumas. "Pseudocyst of the auricle" is defined as intracartilaginous cavity lacking epithelial lining. Thus, according to previous reports "pseudocysts" are supposed to occur due to chondromalacia within the cartilage. We recently observed four cases of "pseudocyst of the auricle" characterized by non-inflammatory, merely painless swellings on the anthelix part of the ears without history of any previous trauma. Incisional biopsies were taken from the dorsal side of the concha and freed 2 to 2.5 ml of viscous serous fluid. Histopathological examination of biopsy specimens showed regular epidermis overlying normal reticular dermis and perichondrium as well as regular cartilage in all patients. In the fourth patient the biopsy, additionally, revealed a tiny intracartilaginous cavity measuring 1 x 4 micrometers in diameter. Histopathologically "pseudocysts of the auricle" are reported to represent small intracartilaginous hollows lacking epithelial linings. Following previous descriptions they are located within the cartilage of the concha of the ear. Because of the small size of the intracartilaginous cavity they are unable to contain more than a few microliters of fluid. Therefore cystic swellings of the auricle containing comparatively large amounts of serous liquid must be located outside the cartilage. In this context the concept of "pseudocyst of the auricle" as reported, can only be seen as the third face of a coin that shows othematoma on the one and otoseroma on the other side.- - - - - - - - - - ranking = 1.5keywords = cavity (Clic here for more details about this article) |
