Evaluation of the angiographic appearance of subdural hematomas in 100 patients resulted in a new descriptive category, the 'transitional.' Each subdural hematoma was classified as chronic if a membrane was found at surgery, otherwise it was considered acute. Utilizing this three category classification (transitional, crescentic and convex lens) false positive diagnoses of acute subdural hematomas were halved, achieving much greater accuracy than reliance on clinical estimate of the age alone. The transitional shape appears to occur as the subdural hematoma is forming membranes or as the subdural fluid is resorbed from a chronic lesion.
