Symptomatic spinal osteochondromas are rare occurrences in an individual surgeon's experience. Computed tomography or magnetic resonance imaging are the imaging procedures of choice. In the majority of patients with myelopathy or radiculopathy, surgery results in complete relief of symptoms as demonstrated in this case.
Between the years 1970 and 1997, 112 patients with tumors of the lateral ventricle were operated on at the University of Ankara, School of Medicine, Department of Neurosurgery. Seventy-one patients (63.4%) were male and 41 patients (36.6%) female. Headache (35.7%), nausea and vomiting (22.3%) were the most common presenting complaints. Papilloedema (42.9%), motor and sensory loss (25%) were the most common findings at neurological examination. Complete tumor removal was accomplished in 38.4% of the patients. Histopathologically, the most commonly seen types of the tumor were ependymoma (25%) and astrocytoma (21.4%). Among the various approach, the anterior transcortical (53.6%) and the posterior transcortical (16%) were the most commonly used. Eleven patients were reoperated for tumor recurrence. After surgery, radiation therapy was also performed on fourty-two patients. The morbidity and mortality rates were considerably higher before 1976 when the use of microneurosurgical techniques was introduced. After this, our morbidity and mortality rates decreased dramatically. The overall surgical mortality rate was 7.1% before 1976; during the last 10 years (n:46), it was 6.5%. In this report, our choice of operative approaches and the results will be discussed.
Multiple hydatid cysts of the brain are uncommon and may be either primary or secondary. We report a 12-year-old child with multiple hydatid cysts of the brain occurring 1 year after surgical rupture of a primary large and infected cerebral hydatid cyst. Surgical removal of hydatid cysts was successfully performed. Albendazole (10 mg/kg twice daily for 12 weeks) was administered to the patient in the postoperative stage.
The authors present a rare case of cavernous angioma mimicking a meningioma in a 58-year-old man who presented with a headache and dizziness. There were no neurological deficits or other neurological symptoms or signs. An extra-axial mass lesion thought to be associated with diffusely well-enhanced falx in the postcontrast sections was noted in the posterior interhemispheric fissure near the posterior part of the corpus callosum splenium. Extra-axial cavernous angiomas (cavernomas) are extremely rare lesions. They most commonly occur in the parenchyma but have been occasionally reported to arise from the dura matter. Dural cavernous angiomas arise from dural sinuses, falx cerebri, tentorium cerebelli, cranial base dura, or internal auditory canal dura and convexity. Parenchymal cavernous angiomas classically have a ring of hemosiderin surrounding the lesions observed on magnetic resonance imaging, but dural cavernous angiomas do not display the same magnetic resonance imaging characteristics and occasionally exhibit a dural tail sign due to which they can often be misdiagnosed as meningiomas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
