Computed tomography in isodense subdural hematoma

Radiology. 1978 Jul;128(1):71-4. doi: 10.1148/128.1.71.


Isodense subdural hematomas, particularly bilateral ones, may be difficult to diagnose with CT. Forty-three cases of subdural hematomas were studied by CT, 7 of which were isodense collections. Obliteration or displacement of the cortical sulci in the zone of the extracerebral collection was present in all 7 cases. Infusion scans demonstrated displacement of a cortical vein away from the inner table of the skull in 3 of the 7 cases. This findins is helpful in accurately predicting the size of the extracerebral collection.
