Résumé
Meningioma rarely manifests as a subarachnoid hemorrhage (SAH), and invasion directly into a major intracranial artery is extremely rare. To the best of our knowledge, meningioma presenting with an SAH associated with major intracranial arterial invasion has never been reported. We present a case of sphenoid ridge meningotheliomatous meningioma manifesting as an SAH without pathologically atypical or malignant features, due to direct tumor invasion into the middle cerebral artery.

Osteopathia striata with cranial sclerosis is a very rare sclerosing bone dysplasia that is characterized by the radiological appearance of longitudinal striations at the metaphysis of the long bones associated with cranial sclerosis. Here, we report a 10-month-old female infant and a 31-year-old male, who were diagnosed incidentally by showing longitudinal sclerotic lines symmetrically in the long bone ends and basal sclerosis of the cranium. The diagnostic linear striation was found not only in the long bones but also in the ribs and phalanges, which are very rare sites for striation. We discuss the radiology findings of osteopathia striata with the possible complication of cranial sclerosis.
