A Case of Sarcoidosis Masquerading as Right Middle Lobe Consolidation.

Sarcoidosis is a multisystem granulomatous disorder that is characterized histologically by noncaseating granulomas. Typically, it presents clinically in young adults with initially one or more of the following: hilar lymphadenopathy, pulmonary reticular opacities, and skin, joint, and/or eye lesion. Radiographic findings commonly include bilateral hilar and mediastinal lymphadenopathy and pulmonary reticular opacities but may resemble pneumonia with airspace consolidation and opacities.
