The false falx and tentorium sign: case report of subdural haematoma and sickle cells disease

Abstract

The increased density in the basal cisterns and the subarachnoid space on CT scans is a well-known characteristic of subarachnoid hemorrhage. Have been described diverse conditions that can emulate subarachnoid hemorrhage, such as purulent leptomeningitis, intrathecal contrast material and leak of high doses of intravenous contrast material to the subarachnoid space. We present the case of a male patient who presented a subdural hematoma in the setting of non-diagnosed sickle cell disease. To this patient was performed a panangiography which discard any aneurismal hemorrhage origin.
