Nodular pulmonary sarcoidosis is a very rare manifestation of thoracic sarcoidosis, varying from 1.6% to 4% of patients with sarcoidosis.
Pathology
They are thought to typically consist of coalescent granulomas.
Radiographic features
CT
There may be distinct nodules measuring from 1 to 5 cm in diameter 1. There may be an overall peripheral predilection and there can be associated mediastinal lymphadenopathy 2.
History and etymology
The first case of nodular sarcoidosis is thought to have been reported by McCord and Hyman in 1952 with multiple bilateral nodules imitating metastatic disease 1.
