Résumé
Most nontraumatic subarachnoid hemorrhages are induced by the rupture of a saccular aneurysm. Acute nontraumatic cortical subarachnoid hemorrhage at the convexity of a cerebral hemisphere is a relatively rare occurrence with various vascular or nonvascular causes. Furthermore, the clinical manifestation of acute nontraumatic cortical subarachnoid hemorrhage differs from that of aneurysmal rupture. We experienced five cases of acute nontraumatic cortical subarachnoid hemorrhage with diverse neurological symptoms. Consecutive workup revealed the various etiologies of that hemorrhage.

We present a case report of a 45-year-old woman with spontaneous pneumocephalus accompanied by pneumorrhachis of the thoracic spine, which is a very rare condition generally associated with trauma and thoracic or spinal surgery. The patient had undergone an operation about 10 years earlier to treat a giant cell tumor of the thoracic spine. During the operation, a metallic device was installed, which destroyed the bronchus and caused the formation of a broncho-paraspinal fistula. This is the suspected cause of her pneumocephalus and pneumorrhachis. To our knowledge, this is a very rare case of pneumocephalus accompanied by pneumorrhachis induced by metallic device, and when considering the length of time after surgery these complications presented are also exceptional.

Postpartum cerebral angiopathy is a main cause of postpartum stroke. We describe a 27-year-old woman with postpartum cerebral angiopathy after taking bromocriptine. Her brain FLAIR MR image revealed several lesions of sulcal hyperintensity. The sulcal hyperintensity in the MR image may be a sequelae of bromocriptine-induced angiopathy during the postpartum period.
