A middle aged woman presented with delusions of infestation and multimodal hallucinations due to an underlying glioma of the corpus callosum. After surgery, the phenomena in question changed and finally disappeared. A recurrence of the tumour caused dementia.

Neurocysticercosis (NCC) is the most common parasitic infestation of the central nervous system. Most cases of NCC are to related and/or associated with inflammation within the cerebral parenchyma. A 71-year-old woman presented with a 4-year history of visual disturbance. This symptom had become aggravated 4 weeks earlier. Her visual acuity gradually decreased and superior hemianopsia was noted. Magnetic resonance imaging (MRI) revealed an enhanced and thickened pituitary stalk accompanying a suspicious mass. The provisional diagnoses were lymphoma, glioma, or other inflammatory conditions. Laboratory studies, including blood and hormonal studies, showed normal findings. Surgical resection was performed. In the pathological examination, degenerated parasitic wall structure was seen and its contents were composed of completely degenerated focal globular structures suggesting the scolex of cysticercus. We report an unusual case of NCC involving the pituitary stalk which was presented with a juxtasellar tumor. The possible underlying mechanisms are discussed with a review of pertinent literature.

Filariasis, an endemic zoonosis in the Southeast Asia region, has been reported to affect various organs as well as the central nervous system (CNS). Inflammatory reactions mimicking those from neoplastic lesions clinically and radiologically have been reported in the breast and urinary bladder. To date, a CNS manifestation of filarial infestation has been reported in the form of meningoencephalitis. The authors here present an interesting case of a young man presenting in status epilepticus, which on radiological evaluation appeared to be a glioma. However, postoperative histopathological examination changed the provisional diagnosis to a filarial infection of the CNS mimicking a primary CNS neoplasm.
