Hydroxyurea chemotherapy in the treatment of meningiomas

Herbert B. Newton

WHO Grade III tumor. Each patient was treated with hydroxyurea (20 mg/kg/day; equivalent to 1000, 1500, or 2000 mg/day) and was then monitored every 3 months. Significant enlargement was not noted in any of the tumors during the course of treatment. Two of the patients with Grade I meningiomas had 60 to 75% shrinkage over a 6- to 10-month follow-up period, as documented on serial MR images. In addition, one patient with tumor-related trigeminal neuralgia and abducens nerve paresis noted significant improvement in neuralgic pain and extraocular muscle function after

Operative management of brainstem cavernous malformations

would be expected given the presence of these tracts along the entire axis of the brainstem. 9 , 36 Oculomotor abnormalities are more common with lesions of the mesencephalon compared with other portions of the brainstem. 36 Ataxia, meanwhile, has been reported more commonly with lesions situated toward the medulla—although this is not always the case, as cerebellar long tracts and cerebellar peduncles are present in all segments of the brainstem. 22 , 36 Vertigo and nausea have been noted in conjunction with pontine lesions. 36 Trigeminal neuralgia has been

Öke published all of his neurosurgical cases in 14 manuscripts in various medical journals. 11 , 12 Among Turkish surgeons who visited western neurosurgical centers, Capt. Mustafa Sakarya was the first to visit the US. 10 He was trained in general surgery, and was then sent to the US for additional neurosurgical training in 1938. Capt. Sakarya was the fellow of Dr. Walter E. Dandy and worked for 9 months at Johns Hopkins Hospital. He
