An Atypical Case of Pulmonary Sarcoidosis

Abstract Sarcoidosis is a multisystem, granulomatous, inflammatory disease, of uncertain aetiology, ubiquitous, much more common in the female population. The age at onset is usually between 30 and 50 years, also having a second peak of incidence in the immediate post-menopausal period. Respiratory system or lymphatic system involvement is present in about 90% of sarcoidosis cases, usually being short-lived and self-limiting, but sometimes the disease can become chronic and less often it can progress to irreversible pulmonary fibrosis, complicated with pulmonary hypertension followed by chronic pulmonary heart disease with cardio-respiratory failure and death. We present the case of a patient presenting a rare, nodular form of sarcoidosis, in which multiple calcifications, both parenchymal and lymphatic, were identified by imaging, most likely with a long-term evolution of the disease beforehand, but with a completely preserved pulmonary function.
