1/7. Congenital intraorbital optic nerve cyst. Case report.Congenital cystic lesions of the optic nerve are exceedingly rare; only one case is reported in the world literature. The authors describe a case of congenital simple glial cyst in the intraorbital portion of the optic nerve with a brief review of the literature and comment on its histogenesis. A 45-day-old male infant was admitted to the hospital because of progressive proptosis and hypotropia in the left eye, which had been present since birth. magnetic resonance imaging of the left orbit revealed an ovoid, well-demarcated, homogeneous cystic mass in the intraconal retrobulbar area. The mass compressed the left eyeball with downward and lateral displacement. The wall of the cystic mass was very thin, and a needle puncture of the cyst released clear, colorless, watery fluid. The cystic wall was lined by loose astroglial nerve fibers with some scattered glial cells.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |

Malignization of an arachnoid cyst.A case of evolvement of fibrosarcoma from a supratentorial arachnoid cyst (verified in surgery five years before) is presented, with brief comments on the embryonic origin of the tissues involved.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
3/7. Large abdominal-pelvic cyst: an unusual presentation of hepatic echinococcosis.The authors present an unusual form of hepatic echinococcosis characterized by a cystic mass that occupied the whole abdomen. The clinical features and the results of the diagnostic imaging procedures (ultrasound, computed tomography) are commented on.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |

5/7. Massive orbital cyst of the lateral rectus muscle after retinal detachment surgery.A 73-year-old white man presented with painless proptosis of the right eye 18 years after retinal detachment surgery on the same eye. Computed tomography (CT) showed a mass in the area of the lateral rectus muscle and magnetic resonance imaging (MRI) defined the multiloculated cystic mass to be located within the lateral rectus muscle. At the time of surgery, a large, thin-walled cystic lesion was found within the lateral rectus muscle. Histopathologically, the cystic mass was of nonkeratinizing stratified squamous conjunctival epithelium. Massive orbital cysts after retinal detachment surgery are rare. The authors review the literature and comment on the differential diagnosis and presumed pathogenesis of this lesion.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
6/7. Laparoscopic approach for treatment of a primary splenic cyst.We present the case of a 24-year-old woman with a symptomatic primary splenic cyst, and we relate our first experience with laparoscopic resection of the extrasplenic wall of the cyst. The procedure was successful, and the patient was discharged asymptomatic two days following surgery. We describe the surgical technique used and comment on some pathologic and tactical aspects. We conclude by remarking on the association of the beneficial advantages of minimally invasive surgery with the demand for more conservative splenic surgical procedures. Therefore, laparoscopic partial cystectomy may be a useful alternative for patients who require an effective treatment for nonparasitic splenic cysts.- - - - - - - - - - ranking = 1keywords = comment (Clic here for more details about this article) |
7/7. Cystic goiter with squamous-cell metaplasia--case report and comment on origin of squamous-cell cyst.A 53-year-old woman with a left unilocular cystic goiter of the size of a small orange was reported. Approximately four-tenths of the innter surface was lined with several layered squamous epithelium with few follicles remaining. A gradual metaplastic transition from the follicular epithelium to the flattened cuboidal and to the squamous epithelium was observed. The ultimobranchial body has been understood to be a possible origin of an entirely squamous cell cyst of the thyroid, three of which have been reported. The difference between the ultimo-branchial and metaplastic origins will be discussed, and a new designation-primary (ultimo-branchial) and secondary (metaplastic) squamous-cell cyst will be proposed.- - - - - - - - - - ranking = 4keywords = comment (Clic here for more details about this article) |
