Lipomas of the pineal region

Surgical Neurology

Abstract

Intracranial lipomas are rare lesions, representing 0.02% of operated intracranial lesions. Lipomas of the pineal region are even rarer and are reported occasionally in the literature. This is possibly because of the fact that they may give rise to clinical symptoms rather infrequently. When they become symptomatic, some form of management must be contemplated. Four cases of lipomas of the pineal region observed in our institute during a 5-year period were investigated, and clinical-diagnostic features were studied. Two of the cases were symptomatic and were submitted to direct surgical treatment. Computed tomography (CT) scanning was performed in 3 cases and magnetic resonance imaging (MRI) in all 4. MRI angiography was performed in the last case. The appearance of the lipoma was quite pathognomonic in the neuroimaging diagnostic test. The infiltrative character of the lesion was better defined by MRI. MRI angiography gave evidence of the upward displacement of the deep veins. Direct surgical approach was performed via a right occipital transtentorial approach in one case and supracerebellar route in another. Neither approach appeared to be superior to the other one. Total removal of the lesion seemed to be impossible because ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
