1/325. optic nerve cysticercosis in the optic canal. The authors present a first case of cysticercosis in the optic canal in a fifteen-year-old female patient. Cysticercosis of the optic nerve is rare. A cyst in the optic canal, beneath the sheath of the optic nerve, has never been reported. The patient presented with rapidly diminishing vision in the left eye, headache and papillitis. A magnetic resonance imaging revealed a cystic lesion at the entrance of the optic canal. Surgery performed was a transcranial orbitotomy which included deroofing of the optic canal and removal of the cyst from under the sheath of the optic nerve. The cyst proved to be cysticercus histopathologically. The outcome was a remarkable visual recovery. ( info) |
2/325. Multilocular cysticeral and hydatid cysts of the brain: a report of three cases. Three cases of multilocular parasitic brain cysts are presented; two cases of specific form of neurocysticercosis and one case of multilocular hydatid cyst. MRI shows features seen in other cystic lesions of the CNS. In all cases the diagnosis was established by neurosurgical brain biopsy. The authors indicate that the parasitic disease should be taken into consideration in differential diagnosis of tumor-like cystic brain lesions. ( info) |
3/325. Cysticercosis of the cerebellopontine angle cistern mimicking epidermoid inclusion cyst. We report a case of a cystic lesion in the left cerebellopontine (CP) angle cistern. The magnetic resonance (MR) imaging features closely resembled an epidermoid inclusion cyst, and was interpreted as such. However, at surgery and on histopathological examination the lesion was found to be a cysticercus cyst. It may be impossible to distinguish between the two by imaging. The MR imaging findings of cysticercosis, epidermoid and other common differentials are discussed. ( info) |
4/325. Case studies in international medicine. family physicians in the united states are increasingly called on to manage the complex clinical problems of newly arrived immigrants and refugees. Case studies and discussions are provided in this article to update physicians on the diagnosis and management of potentially unfamiliar ailments, including strongyloidiasis, hookworm infection, cysticercosis, clonorchiasis and tropical pancreatitis. albendazole and ivermectin, two important drugs in the treatment of some worm infections, are now available in the united states.

| We describe a case of healed neurocysticercosis with seizures, in which magnetisation transfer contrast showed a large area of presumed perilesional gliosis not visible on conventional spin echo magnetic resonance imaging. ( info) |
6/325. Fungus-like hyphochytrids associated with human disease. We report two cases, with liver and brain abscess, respectively, where fungus-like organisms belonging to the Hyphochytriomycota were found at the site of inflammation together with peptococcus in the first and cysticercus cellulosae in the second case. This is the first time these groups of organisms have been reported in human material. The role of hyphochytrids in human pathology remained uncertain as they were found together with already known human pathogens. ( info) |
7/325. optic nerve cysticercosis: imaging findings. We present the imaging findings of retrobulbar optic nerve cysticercosis in a 50-year-old woman with a 6-month history of vision loss. Contrast-enhanced CT revealed an approximately 7-mm ring-enhancing cyst with a mural nodule located in the anterior portion of the left optic nerve. A contrast-enhanced MR imaging study revealed a cystic lesion with peripheral enhancement of the mural nodule. Sonography showed a cystic mass with a focal area of increased echogenicity corresponding to the mural nodule. ( info) |
8/325. Subcutaneous cysticercosis involving the eyelid: sonographic diagnosis. A 25-year-old man and a 14-year-old boy presented with neurocutaneous cysticercosis involving the eyelid. Both patients had hundreds of scattered subcutaneous cysticerci. They were arranged in clusters over the sternocleidomastoid muscle in the neck. Such clustering of cysticerci is highly suggestive of central nervous system (CNS) involvement, as both the sternocleidomastoid muscle and the CNS are supplied by the carotid artery and cysticerci travel via the hematogenous route. We used ultrasonography to diagnose subcutaneous cysticercosis, which showed characteristic low reflective cysts and high reflective scolices inside. Although subcutaneous cysticerci are inconsequential, their verification is important in the diagnosis of more severe CNS involvement. They may be confused with other painless swellings such as lymphadenopathies, neurofibromas, and epidermoid cysts. ( info) |
9/325. Cysticercosis of the optic nerve. Cysticercosis of the optic nerve has been reported only twice in the literature. A case of optic nerve cysticercosis in a 50-year-old woman with atypical optic neuritis is reported. Computerized tomography showed a thickened left optic nerve with a ring-enhancing lesion containing an eccentric nodule. An enzyme-linked immunosorbent assay test for cysticercosis further established the diagnosis. The patient was treated with oral prednisolone and albendazole, with no improvement in vision. ( info) |
10/325. A case of subcutaneous cysticercosis (cysticercus cellulosae cutis). Cysticercosis is an infection resulting from the larval form of the pork tapeworm, and domestic infection is rare in japan. We report a case of cysticercus cellulosae cutis in a Japanese woman who was thought to be infected in an endemic area and offer a brief review of the literature. ( info) |
