1/372. papilledema associated with a sacral intraspinal cyst.A rare case of papilledema associated with a large sacral intraspinal cyst is described in a 34-year-old male. Symptoms were aggravated by heavy work and consisted of low back pain, headache, dizziness and episodic vomiting. papilledema was observed on ophthalmological examination. A valvular mechanism was found to exist between the normal spinal sac and the huge sacral cyst. Division of the valvular fistula combined with a dural plastic operation brought complete relief of all symptoms.- - - - - - - - - - ranking = 1keywords = headache, back (Clic here for more details about this article) |
2/372. Coronal computed tomography: indications and accuracy.The application of wide aperture scanners to neuroradiology permits improved anatomic definition and localization of intracranial and intraorbital lesions. Coronal scans are most useful in demonstrating lesions of the skull base and apex, distinguishing between infra- and supratentorial lesions, and in determining if a lesion is intra- or extraaxial. Limitations of coronal scans include discomfort in positioning, high spatial frequency artifacts, and additional radiation exposure.- - - - - - - - - - ranking = 2.3219448309099keywords = discomfort (Clic here for more details about this article) |
3/372. Choledochal cysts: a clinical and radiological evaluation of 21 cases.Choledochal cysts are predominantly a disease of children, the majority of which are female. The classical symptoms usually form part of a triad of jaundice, abdominal pain and a mass. The radiological features may be non specific and specific. Our experience of 21 cases with particular emphasis on the specific features which outline the cyst are presented.- - - - - - - - - - ranking = 2.1326538733091keywords = abdominal pain (Clic here for more details about this article) |

5/372. Rare occurrence of intracerebellar colloid cyst. Case report.colloid cysts are rare intracerebral lesions that are preferentially encountered within the third ventricle. There are only a few reports in which colloid cysts are described in other locations such as the fourth ventricle. A symptomatic intracerebellar colloid cyst in a 45-year-old woman is described. The patient presented with headache, gait disturbance, and nausea. Neuroradiological imaging revealed compression of the fourth ventricle, hydrocephalus, and an intracerebellar cystic lesion measuring 4 x 5 cm that had a small peripheral solid portion. The cyst was successfully removed via a paramedian suboccipital approach. Postoperatively, the patient recovered quickly. The findings in the present report represent an additional example of the broad spectrum of cystic lesions encountered in the cerebellum.- - - - - - - - - - ranking = 0.94515938568168keywords = headache (Clic here for more details about this article) |
6/372. Retroperitoneal and mesenteric cysts.Retroperitoneal and mesenteric cysts are rare abdominal tumours. This report is a presentation of three cases. One patient had large retroperitoneal cyst which was accidentally discovered, another patient had mesenteric cyst presenting with abdominal pain, and the third patient had emergency admission due to infection of a large mesenteric cyst. The literature on this condition is reviewed.- - - - - - - - - - ranking = 2.1326538733091keywords = abdominal pain (Clic here for more details about this article) |
7/372. Adrenal endothelial cyst with massive central calcification.A 55-year-old woman was treated for a rare case of adrenal endothelial cyst that was detected incidentally during management of abdominal pain. Computed tomography of the tumor displayed massive central calcification and a fluid-fluid level by intracystic hemorrhage. magnetic resonance imaging showed an intracystic papillary part with calcification. After surgery, the tumor was diagnosed as an angiomatous type of adrenal endothelial cyst.- - - - - - - - - - ranking = 2.1326538733091keywords = abdominal pain (Clic here for more details about this article) |
8/372. Pyrofluid inhalation in "fire-eaters": sequential findings on CT.We report the sequential computed tomography (CT) findings in two fire-eaters after accidental inhalation of pyrofluid. The initial chest radiographic findings were ambiguous and the interpretation of the radiographs was biased by clinical history unrelated to fire eating. On CT, pneumatoceles were the major findings in both patients. The pneumatoceles resolved rapidly, leaving only minimal scarring. Our cases illustrate the sequential evolution of pneumatoceles in fire-eaters after the inhalation of pyrofluid and documents the rapidity with which the lesions regress. The rare accidental inhalation of pyrofluid in fire-eaters may produce a puzzling clinical and radiographic picture and can be confused with other lung disorders.- - - - - - - - - - ranking = 0.16323478617424keywords = chest (Clic here for more details about this article) |
9/372. Familial fatal and near-fatal third ventricle colloid cysts.BACKGROUND: Despite having a presumed congenital origin, familial cases of colloid cysts have been reported only rarely. The first case of a brother and sister with colloid cysts is reported here, and the relevant literature is reviewed. methods: A 25-year-old man presented with a 24-h history of headache and vomiting. He rapidly became unconscious and fulfilled the criteria for brain death on arrival at hospital. No surgical intervention was performed. RESULTS: The patient's sister presented at the age of 41 with headaches and rapidly became unconscious. The sister had urgent bilateral ventriculostomies. followed by transcallosal removal of a colloid cyst. CONCLUSIONS: These cases support the hypothesis that colloid cysts are congenital lesions and provide some evidence of a possible genetic predisposition to their formation. Sudden death remains a real risk for patients harbouring a colloid cyst.- - - - - - - - - - ranking = 1.8903187713634keywords = headache (Clic here for more details about this article) |
10/372. Endoscopic treatment of symptomatic septum pellucidum cysts: with some preliminary observations on the ultrastructure of the cyst wall: two technical case reports.OBJECTIVE AND IMPORTANCE: We describe two patients with symptomatic septum pellucidum cysts managed by endoscopic fenestration. In each case, tissue from the cyst wall was studied to define the origin of the cyst wall and fluid. CLINICAL PRESENTATION: The patients, a 6-year-old boy and a 42-year-old man, each presented with headaches and a syncopal episode. Imaging studies demonstrated large septum pellucidum cysts with obstruction of the foramina of Monro. INTERVENTION: The patients underwent endoscopic transventricular cyst fenestration with a 4-mm steerable fiberscope. The fenestrations were created to allow communication with the right and left lateral ventricles. In one patient, adhesions between the cyst wall and the foramen of Monro were lysed with endoscopic monopolar cautery. Tissue from the cyst walls was removed for examination by electron microscopy. Postoperatively, the headaches and syncopal episodes resolved in both patients. CONCLUSION: Endoscopic fenestration of symptomatic septum pellucidum cysts produces immediate relief of the mass effect of the cyst and resolution of associated symptoms. Cannulation of the lateral ventricle before cyst fenestration prevents inadvertent injury to the fornices, thalamus, internal capsule, caudate nucleus, and septal and thalamostriate veins. The endoscopic approach allows the surgeon to ensure communication within the ventricular system, thus avoiding placement of a shunt. Preliminary ultrastructural analysis indicates that the cyst walls derive from the septum pellucidum rather than the choroid plexus or arachnoid. The cellular machinery necessary for fluid secretion was identified in some specimens.- - - - - - - - - - ranking = 1.8903187713634keywords = headache (Clic here for more details about this article) |
