[Pancoast's syndrome secondary to neck metastasis with normal radiography of the thorax]

Servicios de Neumología, Hospital Universitario Germans Trias y Pujol, Badalona, Barcelona.

Pancoast's syndrome is characterized by pain in the shoulders and upper extremities, Horner's syndrome, bone loss and hand muscle atrophy. Bronchogenic carcinoma is the most common cause, although other neoplasms or lung infection are occasionally responsible. An apical mass on the chest film can be seen in over 90% of cases, although apical pleural thickening is sometimes the only radiographic finding. We describe a patient whose clinical picture was highly suggestive of Pancoast's syndrome but whose chest film was normal. Magnetic resonance imaging disclosed a cervical mass adjacent to the brachial plexus that proved to be cervical metastasis from an unknown primary tumor. We emphasize the need to consider the possibility of a metastatic cervical tumor compromising the brachial plexus in patients with a normal chest X-ray but clinical signs highly suggestive of Pancoast's syndrome.
