Neurosarcoidosis Diagnosis & Tests
An examination may indicate single nerve dysfunction (mononeuropathy) or dysfunction of multiple peripheral nerves (sensorimotor polyneuropathy). Signs may mimic diabetes insipidus, hypopituitarism, optic neuritis, meningitis, space-occupying lesions such as tumors, or other neurologic disorders.
A history of sarcoidosis followed by neurologic symptoms is highly suggestive of neurosarcoidosis. Blood tests are nonspecific. A lumbar puncture may show signs of inflammation. Elevated levels of angiotensin converting enzyme may be found in the blood or cerebrospinal fluid (CSF).
If sarcoidosis is suspected but not already known, a chest X-ray often reveals lesions typical of the disorder. Nerve biopsy of affected nerve tissue confirms the disorder.
