Meningeal Carcinomatosis Presenting with Isolated Pseudotumor Cerebri

ABSTRACT

A 46-year-old man presented with a progressive headache lasting for 2 weeks. Initial lumbar puncture revealed a pressure of 31 cm H20 and 30 white cells. His symptoms had worsened despite the treatment of intracranial hypertension. Visual field exam showed marked peripheral constriction and the fundus showed marked papilledema. Cytological analysis of cerebrospinal fluid demonstrated positive for metastatic carcinoma. We report a case of a patient with meningeal carcinomatosis who developed isolated intracranial hypertension with papilledema.
