Cervical sympathetic schwannoma simulating a thyroid nodule

Med J Malaysia. 2002 Jun;57(2):218-20.


Schwannomas are rare tumours arising from peripheral nerve linings. A case of a schwannoma arising from cervical sympathetic chain is presented. The clinical presentation was that of a right solitary thyroid nodule. Intra-operatively, a 3 x 3 cm encapsulated lesion was seen arising posterior to the vagas nerve and attached to the cervical sympathetic trunk. The lesion was excised together with part of the nerve. Post-operatively, the patient developed Horner’s syndrome that persisted. Unitil 2000, less that 50 cased of cervical sympathetic schwannoma have been described in the Englidh literature. A brief description of the pathology, presentation, diagnosis and treatment of this condition is presented.
