Vermian metastasis causing truncal ataxia and hydrocephalus as initial presentation of carcinoma stomach.

The common presentation of carcinoma stomach includes haematemesis, malaena and gastric outlet obstruction. Symptoms due to metastases to the liver and lung as part of the disease progression are usually preceded by the detection of a primary in the stomach. Carcinoma stomach, where the primary is silent, and which presents with truncal ataxia and features of hydrocephalus due to isolated metastatic deposit in the cerebellar vermis is exceptionally rare. The prognosis of such patients is poor and the treatment is palliative.
