Minimally Invasive Resection of Giant Neurocysticercal Cyst

A 55-year-old man from Mexico with history of diabetes mellitus presented to the emergency department with report of worsening dizziness over the preceding several weeks along with progressive gait instability. Despite these symptoms, he remained alert and oriented, and continued working in food preparation. On admission, computed tomography of the head revealed a large, cystic mass situated within the right frontal lobe associated with surrounding edema. Significant right-to-left midline shift, subfalcine herniation, and uncal crowding were noted. Magnetic resonance imaging (MRI) revealed a bilobed, cystic lesion 8.8 cm in largest dimension with surrounding edema and mass effect. The differential diagnosis included malignant or infectious processes. The patient had emigrated from rural Mexico to Connecticut 20 years before hospitalization. He reported regular exposure in early childhood to farm animals. He consumed pork infrequently.
