Radiological aspects of medisatino-pulmonary sarcoidosis

Problem: Mediastino-pulmonary sarcoidosis is the most common form of the disease. Its radiological presentation is variable. Our aim is to study the presentation of the disease on standard radiographs and CT scans. Materials and methods: This is a retrospective, descriptive study covering a period of 20 years, collecting the records of patients followed up for confirmed mediastino-pulmonary sarcoidosis. Results:There were 35 patients with a mean age of 56.69 ± 14.42 (19-83 years). The most frequent parenchymal lesions were micronodules (71.4%), nodules (51.4%) and peribronchovascular thickening (40%). The lobes most affected were the LSD (77.1%) and middle lobe (74.3%). The most frequent lymph node involvement was hilar adenopathy (71.4%), followed by paratracheal adenopathy (60%) and the aorto-pulmonary window (54.3%). Conclusion: Sarcoidosis phenotypes are highly variable. CT scans play a major diagnostic and prognostic role.
