The @entity808 is thought to arise from the schwann cells of the nerve sheath. This @entity5 is usually solitary and may arise from any @entity1897 . It is encapsulated and appears to arise focally on a nerve trunk so that the nerve itself is stretched over the @entity5 rather than running through it as in @entity3292 . This report is unusual as the @entity5 started as a cervical swelling which subsequently grew into the mediastinum simulating a @entity5651 . The @entity1 , a 25 year-old female was referred to the University College Hospital, Ibadan, 24 hours after an attempted thyroidectomy at a private hospital. The history was of a @entity4 of 4 years duration devoid of symptoms of @entity1378 with associated @entity1282 and @entity425 of the left hand. Examination showed an asthenic young @entity1 . Her voice was hoarse but there were no eye signs suggestive of @entity2743 . On the anterior neck was a sutured skin-crease scar over a @entity4 which one could not get below. The left hand showed wasting of the thenar and hypothenar eminences. Thyroid function test results were within normal limits, indirect laryngoscopy showed a left @entity3746 , packed cell volume was 38%. Her chest x-ray showed a huge left retrosternal and apical soft tissue mass displacing the @entity825 to the right (figure 1). A fine needle aspiration cytology was reported as a @entity2621 . A presumptive diagnosis of @entity259 with retrosternal extension was made. At surgery, manipulation of the mass was difficult as the tissue was soft, slimy and @entity397 easily. Severe @entity548 was encountered necessitating a median sternotomy to control the bleeding vessels. Her post-operative period was stormy, however she thereafter made gradual progress to warrant her discharge six weeks post surgery.
