Multimodality Imaging for the Diagnosis and Evaluation of Pulmonary Sarcoidosis.

Sarcoidosis is a multisystem inflammatory disorder characterized by noncaseating granulomas. The diagnosis of sarcoidosis is based on three criteria: clinical history, consistent imaging findings, and histopathology. Radiologists play an important role for the diagnosis and follow-up evaluation of patients with sarcoidosis, which often require a multimodal approach.

Imaging Findings in Aspergillosis: From Head to Toe.

The clinical presentation is dependent on organism and host specifics, with immunodeficiency, allergies, and preexisting pulmonary disease constituting the most important risk factors.
