A mass in the fourth ventricle

Abstract

A 53-year-old man with a history of testicular carcinoma treated by orchidectomy presented with a sudden onset left facial droop and left upper limb weakness that lasted for 4 days. He denied any speech difficulty, lower limb symptoms, seizures, urinary or bowel symptoms. On examination he was alert and orientated, with an occasional head-bobbing tremor. There was mild flattening of the left nasolabial fold, with the remainder of his neurological examination normal. Basic blood investigations were unremarkable. His MRI is shown in Fig. 1, Fig. 2. The tumour was completely removed by a posterior fossa craniotomy. Fig. 2T2-weighted fast spin echo axial MRI showing 1.3 cm hyperintense lobulated lesion in the inferior aspect of the fourth ventricle compressing the posterior aspect of the medulla oblongata. The lesion did not enhance with contrast. View Large Image Figure Viewer Download Hi-res image A mass in the fourth ventricleJournal of Clinical NeuroscienceVol. 16Issue 3PreviewB. Subependymoma.
