Summary

A rare epidermoid tumor in Meckel's cave caused facial numbness. Surgical removal via a subtemporal approach successfully resolved the patient's trigeminal nerve symptoms.

Area of Science:

  • Neurosurgery
  • Neurology
  • Skull Base Tumors

Background:

  • Epidermoid tumors are rare congenital tumors that can occur in the skull base.
  • Meckel's cave is a dural invagination containing the trigeminal ganglion and is a rare location for epidermoid tumors.

Observation:

  • A 27-year-old female presented with a 2.5-year history of right-sided facial hypesthesia.
  • Clinical examination revealed partial loss of touch sensation in the distribution of the right trigeminal nerve.
  • Magnetic resonance imaging identified a tumor at the right petrous apex and cavernous sinus.

Findings:

  • The tumor was diagnosed as an epidermoid tumor.
  • Surgical excision was performed using a lateral basal subtemporal approach.
  • Post-operative recovery showed complete resolution of facial hypesthesia.

Implications:

  • This case highlights the importance of considering rare locations like Meckel's cave for epidermoid tumors presenting with trigeminal nerve symptoms.
  • The lateral basal subtemporal approach is a viable surgical option for accessing and removing tumors in this region.
  • Complete resection of epidermoid tumors can lead to excellent neurological recovery.
