title: Rupture of the lateral ventricle secondary to a fourth ventricle tumour resulting in an indirect nontraumatic cerebrospinal fluid fistula.
abstract: We present a rare indirect nontraumatic cerebrospinal fluid (CSF) fistula secondary to a fourth ventricle ependymoma. The fistula resulted from rupture of the left temporal horn, distant from the tumour. The fistula was well demonstrated by MRI. High-resolution CT demonstrated a defect in the roof of the sphenoid sinus, but no leakage of CSF was seen on CT cisternography.
