Diagnosis With Brief Discussion

Diagnosis
Chest wall schwannoma (neurilemmoma)
Radiologic Findings
Fig 1. Chest PA shows well-defined nodular opacity in the right upper lung field.
Fig 2-6. CT scans of the right side of the chest wall depict a homogeneously enhancing extrapleural nodule (precontrast: 30 HU, postcontrast: 50 HU) that originated from intercostal soft tissue along the course of an intercostal nerve.
Brief Review
Neurogenic tumors, although common in the mediastinum, rarely occur in the chest wall. A schwannoma is a benign, encapsulated, neurogenic tumor arising from the Schwann cells of the nerve sheath. It is a type of peripheral nerve sheath tumor. These tumors often occur in the spinal nerve roots. Most benign tumors of the chest wall, including schwannomas, manifest as slow-growing, painless, and palpable masses. Several thoracic neurogenic tumors tend to arise in the posterior mediastinum. A chest wall schwannoma is a rare entity that arises from the intercostal nerves. Men and women are equally affected in the third and fourth decades of life.
