The differential diagnosis includes- Vascular wedges – pulmonary infarct, invasive aspergillosis Bronchial wedges – consolidation, atelectasis An enhancing mass lesion arising from the right postero–lateral chest wall with a larger intrathroracic and a smaller extrathoracic component [Figure 2a]... Considering the patient's age and site of the lesion, the most likely diagnosis is primitive neuroectodermal tumor (PNET) of the chest wall... Further evaluation with CT scan however revealed a wedge-shaped mass lesion arising from the chest wall... Histopathology of the biopsied tissue confirmed the lesion to be a PNET... Some of the tumors that belong to this group are Ewing's sarcoma (ES), PNET, rhabdomyosarcoma, lymphoma and neuroblastoma... PNET and ES share same chromosomal translocations... PNET commonly affects children and young adults in the first three decades of life... It commonly affects the central nervous system and rarely involves the peripheral sites... The chest wall is the most common peripheral site for PNET, where it is also known as Askin's tumor... Thus, another “wedge” that should be considered in the differential diagnosis of wedge-shaped peripheral lung opacity in young patients is the neoplastic wedge of Askin's tumor.
