title: Positive tensilon test and intracranial tumor: a case report.
abstract: OBJECTIVE
  To report a case of intracranial tumor in a patient with positive tensilon test.
  
  
  METHODS
  Interventional case report. A 19-year-old male presented with left 6th nerve palsy and had a tensilon test, which was highly positive and was diagnosed as having myasthenia gravis.
  
  
  RESULTS
  The neurologist scanned the patient, which showed an intracranial tumor in the floor of the temporal fossa on the left side. The patient had surgery and a schwannoma was removed. The VIth nerve palsy did not improve up to two years after surgery.
  
  
  CONCLUSIONS
  A patient with a positive tensilon test can also have an associated intracranial tumor.
