| The cavum septi pellucidi (CSP) and cavum Vergae (CV) are persistent, primitive, or acquired, midline structures of adult human brain. It is customary to distinguish between the non-communicating and the communicating cava, depending on whether the cavum communicates with the cerebral ventricular system or not. Only a few cases of symptomatic non-communicating cava, called septum pellucidum and cavum Vergae cysts, have been described in the literature. In this study, the authors describe the morphological, histological and histo-immunological characteristics of an additional case of septum pellucidum-cavum Vergae cyst in a forty-year-old man who died the day following a ventriculo-peritoneal shunt. We have found a communication between the CSP and the leptomeningeal space of the anterior interhemispheric fissure, in the absence of subarachnoid haemorrhage. The authors discuss the origin of the intracystic fluid and the classification of the CSP. ( info) |
4212/4526. Possible aetiopathogenetic correlation between primary empty sella and arachnoid cyst. Three cases of surgically treated non-neoplastic diseases of the sella (two arachnoid cysts and one empty sella) are reported. All three patients had visual deficits but no gross endocrine disturbances. The study of these three clinical cases and an analysis of the relevant literature suggest a possible unitary hypothesis regarding the pathogenesis of sellar arachnoid cysts and empty sella.

4213/4526. Reversible cystic disease associated with pulmonary tuberculosis: radiologic findings. PURPOSE: The authors describe radiologic findings of cystic lung disease associated with pulmonary tuberculosis. MATERIALS AND methods: Three immunocompetent women with pulmonary tuberculosis were seen with acute respiratory failure and diffuse bilateral pulmonary opacity depicted at admission chest radiography. The women did not have acquired immunodeficiency syndrome, or AIDS. They were aged 26, 27, and 52 years. RESULTS: Follow-up radiography and computed tomography showed multiple air-filled cystic lesions in both lungs, which disappeared almost completely after antituberculous chemotherapy (isoniazid, rifampin, ethambutol hydrochloride, and pyrazinamide). CONCLUSION: Pulmonary tuberculosis manifested with reversible multiple cystic lung disease in three immunocompetent patients. ( info) |
4214/4526. Acquired subglottic cysts in the low birth weight, pre-term infant. Although subglottic cysts have previously been reported as a cause of airway obstruction in the neonate, they have previously been considered to be a relatively rare cause. Cystic narrowing of the subglottis has been associated with endotracheal intubation. With improving survival of pre-term infants the incidence of the condition could be expected to rise. Prior to 1996, only 58 cases had been reported in the literature. We believe that the true incidence of the condition has been considerably under-reported. Over a six-month period our unit diagnosed five cases of compressible cysts in the subglottis in low birth weight, pre-term infants. All patients underwent diagnostic microlaryngobronchoscopy and vaporization of the cysts by CO2 laser. Three children required more than one procedure. In all cases a satisfactory airway was achieved. The pathogenesis, diagnosis and treatment of the condition is discussed. ( info) |
4215/4526. Cysts of the spleen. Report of a case and review of the literature. Cysts of the spleen are still a rare entity. The present report describes a case of splenic cyst combined with a review of the literature in which classification, clinical manifestations, diagnosis, treatment, and etiology are discussed.

4216/4526. Small cystic insulinoma: value of arterial stimulation venous sampling. Cystic insulinomas are rare, with only three cases having been reported in the literature. It is not difficult to determine the site of such neoplasms, as cystic insulinomas are usually 4-10 cm in diameter. We report a patient with a histologically confirmed cystic insulinoma. This case is unique because of the small size (1.3 cm) of the tumor. Arterial stimulation venous sampling was useful for localizing and distinguishing this tumor from other pancreatic lesions.

4217/4526. Cystic periventricular leukomalacia of the corpus callosum. Periventricular leukomalacia (PVL) is a common finding during neurosonography of preterm infants. Secondary thinning of the corpus callosum is seen following PVL, typically from loss of hemispheric white matter tracts. We report a case of direct involvement of the corpus callosum with PVL, its pathogenesis, and its potential as a cause of corpus callosal thinning. ( info) |
4218/4526. Laparoscopic treatment of a benign splenic cyst. With an understanding of the spleen's important immunologic function, splenectomy for benign splenic disorders has given way to a variety of splenic conservation techniques. Treatment options for benign nonparasitic splenic cysts include partial splenectomy, total cystectomy, or partial cyst decapsulation. External cyst wall decapsulation is a simplified operative procedure that carries no increased risk of cyst recurrence. However, a conventional upper abdominal laparotomy may subject patients to significant morbidity. We successfully performed a laparoscopic partial cyst decapsulation, achieving meticulous hemostasis with use of a laparoscopic-GIA stapling device. The patient tolerated the procedure well and was discharged on postoperative day 2. Follow-up has demonstrated no evidence of recurrent cyst formation. ( info) |
4219/4526. Malignant epithelial neoplasm consistent with primitive cystic hepatic neoplasm with mesothelial differentiation: a case report. mesothelioma are primary tumors of the celiomic cavity and are seen more often in adults than in children: only an estimated 2-5% of all cases present within the first two decades of life. To best knowledge of the reviewing world literature reported to date, no more than 80 proved cases of this tumor have occurred in children. One-third of mesothelioma originate in the peritoneum and two-thirds arise in the pleural cavity. mesothelioma of the liver are extremely rare; a review of the English literature shows only three adult cases that have been reported as fibrous mesothelioma of the liver; experience with these cases suggests a high potential for recurrence, but no progression to malignancy. Cystic mesothelioma occur mainly in adults and are considered to be benign and curable. We describe a case of malignant epithelial neoplasm consistent with primitive cystic hepatic neoplasm with mesothelial differentiation arising in a 3-year-old boy, a condition which has never before been reported in childhood. Malignant primitive cystic mesothelioma is possible that some cases of intraabdominal mesenchymoma or hamartoma with malignant differentiation may have been misdiagnosed in the past; future cases should be fully evaluated, to establish the true incidence of mesothelioma disease in children.

4220/4526. Solitary ileal lipoma presenting with ileocolic intussusception: an unusual cause of enteritis cystica profunda. We report a 63-year-old man who presented with a history of intermittent vague abdominal pain, diarrhea, and weight loss. Colonofibroscopic examination disclosed an ileocolic intussusception with a polypoid tumor on the leading edge of the intussusception. Both double contrast barium enema and computerized tomography of the abdomen confirmed this finding. The excised specimen had an ulcerated ileal lipoma with enteritis cystica profunda on the overlying epithelium. ( info) |
