In childhood and adolescence, pituitary adenomas are rare and half are prolactinomas. However, cystic giant prolactinoma in prepuberty is extremely rare. In this report, we present a 10-year-old boy with a cystic giant prolactinoma who was treated with two-stage surgery as the tumor was dumbbell shaped. To our knowledge, this is the second reported case of(More)
BACKGROUND An association between meningioma, breast cancer, and increased growth of meningiomas during pregnancy, and the luteal phase of the menstrual cycle have been shown in previous reports, but the mechanisms still remain unclear. These data suggest that sex steroids and growth factors may have a role in the growth of meningiomas. This is an important(More)
PURPOSE To prospectively define proton magnetic resonance spectroscopy (MRS) findings of meningiomas, and describe the ability or inability of short- and long-echo MRS to differentiate typical and atypical meningiomas in vivo. MATERIAL AND METHODS Seventeen patients with pathologically confirmed typical meningiomas and six with atypical meningiomas were(More)
BACKGROUND Antifibrinolytic therapy is effective in preventing rebleeding in cases of aneurysmal subarachnoid hemorrhage (SAH). The major disadvantage of this therapy is the increase in ischemic complications, which is supposed to be due to cerebral vasospasm. In this study the effect of short-term antifibrinolytic therapy on arterial vessel narrowing after(More)
OBJECT Chronic subdural hematomas (SDHs) are a local inflammatory process that causes the formation of a granulation tissue often referred to as the external or outer membrane. This membrane has abnormally permeable macrocapillaries. Therefore, exudation from the macrocapillaries in the outer membrane of chronic SDH may play an important role in the(More)
Intracranial chondromas are uncommon intracranial tumours that most frequently arise from the skull base. They can, however, arise from the calvarium or the meninges. In these cases their neuroradiological features may mimic other intracranial tumours. We present two cases of intracranial chondroma, one that originated from the convexity and the other from(More)
Epidermoid cysts are uncommon, benign and slow-growing lesions. They may often reach an enormous size without producing neurological symptoms. Intradiploic epidermoid cysts are nearly 25% of all epidermoids. They are derived from ectodermal remnants that stay within the cranial bones during embryonic development. Intradiploic epidermoid cysts can be located(More)
