Solitary fibrous tumours are rare mesenchymal soft tissue tumours arising from multiple sites in the body including the dura and the intracranial ventricles. These masses are grouped along with rare haemangiopericytomas which form about less than 0.4 % of all CNS tumours. Locally aggressive solitary fibrous tumours closely mimic other dural based tumours most likely meningiomas. We report a case of biopsy proven solitary fibrous tumour from tentorium operated in a 60 year old adult and discuss the imaging features in other related dural based masses.

Extra gastrointestinal stromal tumours (EGIST) are rare neoplasms of the abdomen which have similar morphological and immunohistological features of gastrointestinal stromal tumours. These tumours are not connected to either stomach or intestine and most commonly arise from mesentery, retroperitoneum, omentum etc. We describe a case of EGIST arising from omentum in a 40 year old male patient who presented with features of acute intestinal obstruction.
