[A case of intercostal neuropathy (Th 2-9) due to sarcoidosis]

Neurosarcoidosis is a disorder which presents in 5 percent of cases of general sarcoidosis, in only 10% of which the peripheral nerves are involved. A patient who complained of numbness of the abdomen and back associated with paralytic motion of intestines was admitted. The patient was diagnosed as having neurosarcoidosis of the intercostal nerves (Th2-9) on the basis of abnormality of somatosensory evoked potentials (SEP) and reduced conduction velocity, and evident disease of intrathoracic lesions confirmed by biopsy. Corticosteroid was administered, with relief of symptoms and active response on SEP. Somatosensory evoked potentials and VC were of great value in the diagnosis and follow up of peripheral neuropathy due to sarcoidosis.
