An asymptomatic 48-year-old woman presented to our hospital with a tumor of the rib incidentally diagnosed on a chest roentgenogram. The patient was investigated and underwent tumor resection of the chest wall. The pathologic study revealed that it was cavernous hemangioma.

Diseases of the Chest, 1962
1. It is suggested that the numerous chest-wall syndromes involving painful costal cartilage be identified by the term "Rib syndrome," to indicate a single entity or process. 2. Selections from 50 cases of the "Rib syndrome" are presented, some of which illustrate the interrelationships of the numerous acute types of chest wall conditions as one ...

A 73-year-old woman evidencing an abnormal shadow on chest X-ray film since 1993 was admitted after a tumor of the left 8th rib was diagnosed in 2001. Computed tomography showed a low-density mass with coarse calcification arising from the left 8th rib and protruding into the abdominal cavity.
