Purely tentorial SDH is rarely encountered ^{1) 2)}

Isolated tentorial subdural hematoma without associated neurological deficits represent a benign entity among acute subdural hematoma, with no need for surgical intervention, short length of stay (LOS), and favorable outcome.

Data indicate that for these patients, in the absence of complicating factors, transfer to a tertiary center may not be routinely indicated ³⁾.

Given their rarity and the innocuous clinical course displayed, less attention has been paid to such lesions. The few available reports published in English are confined to isolate cases or limited series of patients ⁴⁾.

Little is thus known about tentorial SDH, despite the many prognostic factors, treatment strategies, and outcomes documented for those involving the brain convexity ⁵⁾.

Traumatic subarachnoid hemorrhage in the left temporal cortical sulci and extra-axial hematoma in the quadrigeminal cisterns and left ambient cistern that extends caudally to the region of the superior cerebellar peduncles and a small hemorrhagic focus in the right cisterna ambiens.
