ABSTRACT
Extradural ectopic meningioma is a rare tumor. We report on an example of microcystic meningioma arising in the skull of an elderly woman. Radiological examination revealed a localized osteolytic lesion in the left parietal bone. At surgery, it was discovered that the tumor was located within the skull without any evidence of extraosseous extension. The light microscopic, immunohistochemical and ultrastructural features were consistent with a microcystic variant of meningioma. To our knowledge, this is the first case of an intraosseous microcystic meningioma, and we believe that this type of meningioma should be considered in the differential diagnoses of myxoid bone tumors of the calvarium.

BACKGROUND: Jugular bulb diverticulum is a rare condition that has never been reported in association with lower cranial nerve palsy. CASE DESCRIPTION: A 54-year-old woman developed acute swallowing disturbance and hoarseness. Neuroradiological examinations demonstrated a jugular bulb diverticulum as well as unruptured internal carotid and basilar tip aneurysms on the same side. Laboratory data for both serum and cerebrospinal fluid were normal. Steroids were given, and the cranial nerve palsy disappeared within 1 month. The aneurysms were successfully clipped. During the follow-up period of more than 1 year, the patient has done well and has no neurological deficit. CONCLUSION: This is the first reported case of jugular bulb diverticulum associated with a lower cranial nerve palsy and multiple aneurysms. We recommend close observation of patients with this condition regardless of its clinical presentation.
