Sarcoid


Frontal (image 1) and lateral (image 2) chest radiograph show innumerable small pulmonary nodules scattered throughout both lungs. These nodules are confirmed on maximum intensity projection from chest CT (image 3). Right hilar adenopathy (arrow) is also evident on chest CT (image 4). Abdominal CT (image 5) displays abnormal kidney morphology. Sarcoidosis, a multisystem granulomatous disorder, typically presents with pulmonary nodules, effusions, and hilar adenopathy. Renal involvement is rare but can manifest as granulomatous interstitial nephritis.


Chest x-ray shows innumerable, small calcified pulmonary nodules consistent with prior granulomatous infection. Histoplasmosis is endemic in the Ohio River Valley. Findings include calcified pulmonary nodules, calcified hilar lymph nodes, and splenic calcifications. #ThoraxThursday

80YO male. Follow up chest CT for 'nodules' on an abdominal CT. No significant pulmonary history.

Axial (image 1) and coronal (image 2) CT images of the chest in a patient with granulomatosis with polyangiitis show large thick wall pulmonary cysts. Granulomatosis with polyangiitis commonly affects the lungs, the kidneys, and the sinuses. In the lungs, pulmonary nodules with cavitation, pulmonary hemorrhage, and reticular nodular opacities may be present. On CT there are multiple nodules of variable size in a peribronchial vascular distribution.

A 40-year-old man presented to his general practitioner with a persistent non-productive cough of six months' duration and progressive development of raised, discolored skin lesions on the anterior surfaces of both lower legs. He reported no significant past medical history and denied fever, night sweats, or weight loss. Physical examination revealed multiple tender, erythematous nodules over the pretibial regions bilaterally. Initial investigations included a chest radiograph, which revealed bilateral hilar lymphadenopathy with prominent perihilar shadowing and reticulonodular infiltrates in the mid and upper zones.


A 52-year-old man presented with a 20-minute history of chest pain radiating to the left shoulder and neck, associated with dyspnea and diaphoresis.
