Abstract
Primary pleural rhabdomyosarcoma is an extremely rare intrathoracic malignancy. We present a case of a previously healthy 2-year-old male complaining of cough and shortness of breath. The plain film, CT and MRI descriptions of this pleural tumor are presented. This is a fast growing tumor that is indistinguishable radiographically from other large intrathoracic tumors such as pleuropulmonary blastoma.
Highlights
Rhabdomyosarcoma is the most common malignant soft tissue tumor in the pediatric age group and usually arises in the head and neck region
Four more cases have been listed in the Intergroup Rhabdomyosarcoma Study (IRS) but without documentation of its imaging characteristics [5]
We present a case of a primary pleural embryonal rhabdomyosarcoma describing its characteristics on plain radiography, CT and MRI
Summary
Rhabdomyosarcoma is the most common malignant soft tissue tumor in the pediatric age group and usually arises in the head and neck region. Only 5 cases of pleural rhabdomyosarcoma have been reported in the English literature. A single case report 20 years ago documented an intrathoracic mass, histology-proven to be a primary pleural rhabdomyosarcoma [4]. They failed to demonstrate a tumor aside from the 5 mm pleural thickening with associated pleural effusion and were not able to characterize the radiologic image of this lesion. Four more cases have been listed in the Intergroup Rhabdomyosarcoma Study (IRS) but without documentation of its imaging characteristics [5]. We present a case of a primary pleural embryonal rhabdomyosarcoma describing its characteristics on plain radiography, CT and MRI
