Diagnosis With Brief Discussion

Diagnosis
Mucoepidermoid carcinoma, bronchus intermedius
Radiologic Findings
Chest radiograph showed combined collapse of RML and RLL with mass in bronchus intermedius. Chest CT after contrast enhancement showed homogeneous well enhancing soft tissue mass within bronchus intermedius associated with complete obstruction of RML and RLL.
Brief Review
Second most common form of tracheobronchial gland tumors, accuring between ages of 3 months to 78 years, half of them, younger than 30 years. Radiologic findings are mostly related to their location and size and may manifest as solitary mass, consolidation and collapse. On CT, they usually consist of a smoothly, lobulated oval to round nodule of 1 cm in size. Mild degree of contrast enhancement is usual and generally with homogeneous pattern. Punctate calcifications can be seen upto 50 %. On FDG PET imaging, they were usually known to show marked uptake, not like this case.
