[Arachnoid cyst of the temporal fossa. Subdural hematoma. Contribution of MRI].
A 20-year old man presented with an arachnoid cyst of the middle fossa and a subdural hematoma (SDH). An intra-cystic hemorrhage masked the presence of the SDH on CT. MRI demonstrated a communication between cyst and SDH. The mechanism of SDH formation is discussed.
