THE TRIGEMINAL NERVE

Ancient Schwannoma of the Trigeminal Nerve Mimicking High Grade Lesion

  Ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. A seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. Imaging findings were suggestive of left temporal high grade lesion. During surgery there was well...

Experimental trigeminal nerve injury.

The successful reinnervation of peripheral targets after injury varies with the axonal population of the nerve that is injured and the extent of the dislocation of its central component from the peripheral endoneurial tube. Larger-diameter axons such as those supplying mechanoreceptors recover more readily than narrower axons such as those supplying taste. A complex, bi-directional interaction ...

trigeminal pain and its distribution in different trigeminal nerve branches

Endoscopic vascular decompression of the trigeminal nerve.

BACKGROUND Microvascular decompression is an effective method of treatment in trigeminal neuralgia. It may fail if a compressing vessel is overlooked during surgery. The endoscope has an edge over the microscope in visualizing such conflicts. MATERIALS AND METHODS This is a prospective study of 51 patients. Preoperative computed tomography and magnetic resonance imaging scans were performed i...

Primary lymphoma isolated to the trigeminal nerve.

included computed tomography (CT), magnetic resonance imaging (MRI) (Figure 1A and B), and cerebrospinal fluid analysis. Medical treatment for trigeminal neuralgia was started, however this proved to be unsuccessful. His pain worsened, and repeat MRI showed an enlarged, non-enhancing lesion at the root entry zone of the trigeminal nerve (Figure 1C). A neoplastic etiology was suspected, and the ...
