This article describes a case of prominent emissary veins of the hypoglossal canal protruding into the cerebellomedullary cistern mimicking disease, such as a nerve sheath tumor. The diagnosis and differentiation in this instance were confirmed by MR angiography and a review of alternative imaging planes. A diagnosis of hypoglossal canal lesions should be made with caution, as these lesions are...

Dear Editor, Young adults are frequently presented with headaches due to various causes. Atypical facial pain, renamed as persistent idiopathic facial pain (PIFP) is a poorly understood condition with the pain described as a persistent facial pain that does not have the characteristics of cranial neuralgias and which is not attributable to another disorder.1 PIFP must be differentiated from oth...

=Abstract=The first Korean case of a symptomatic Rathke's cleft cyst in a 14-year old boy is described. His chief complaint was headache of 2 months' duration and he had diabetes insipidus, hypopituitarism and decreased visual acuity on both sides. The computerized tomography scannng revealed an isodense small round mass at the suprasellar cistern with partial enhancement. The cyst was removed ...

T technology of building aqueducts carrying the water in near and distant watersheds together with giant cisterns that store the water to meet the water need of the public in big settlements is a gift of Rome to the history of architecture. The most beautiful example of engineering science and water architecture in İstanbul is Yerebatan Palace that has also become famous as a large basilica cis...

We present a case of a 28-year-old woman with a cerebellopontine angle and prepontine cistern epidermoid cyst with unusual signal intensity. She presented with cranial nerve neuropathy and unsteady gait. MR imaging showed a tumor mass with central area of hemorrhage and a focal area of heterogeneous signal intensity with spotty enhancement, which correlated histologically to old blood in a cyst...

The PComA arises as a branch of supraclinoid part of ICA and passes backwards and medially, medial to occulomotor nerve and joins the PCA at the junction of P1 and P2 segments of PCA. Surgically the PCA is divided into three segmentsP1, P2 and P3 and supplies occipital lobe and inferomedial surface of temporal lobe. P1 is the precommunicating segment and P2 is lateral to junction of PComA exten...

The case of a rare, mature teratoma of the oculomotor nerve manifesting as an interpeduncular cistern mass is presented. A basilar tip aneurysm initially was suspected on the basis of lesion location and MR imaging appearance. Subsequent CT and catheter angiography studies were atypical for aneurysm, leading to surgical biopsy. Pathologic analysis revealed a well-circumscribed mass composed of ...

Two cases of intracranial penetration of a plastic or wooden chopstick via the optic canal are described. CT scans showed the chopsticks as linear hypodense structures in the suprasellar cistern contiguous with the optic canal. In one case, MR imaging was performed, which clearly depicted the foreign body and adjacent brain structures. Although they are extremely rare, transorbital intracranial...
