The Sudden Development of Multi-Organ Lesions in a Patient With Pulmonary Sarcoidosis: A Case Report

Abstract

Introduction. Sarcoidosis is a systemic granulomatous inflammatory disease that can involve almost any organ system in the human body. It most frequently presents with pulmonary infiltrates, hilar lymphadenopathy, and skin lesions. Clinical and subclinical involvement of other organ systems is not uncommon. However, the simultaneous development of clinically apparent multisystem sarcoidosis is very rare. Case Description. This 44-year-old Caucasian man presented to an outpatient clinic with a 2-month history of fatigue, night sweats, weight loss, loss of appetite, and mild abdominal discomfort. Initial laboratory finding showed elevated liver enzymes. Imaging studies revealed cirrhotic liver with steatosis, few enhancing hepatic masses, and multiple enlarged periaortic and portocaval lymph nodes. Liver biopsy revealed scattered necrotizing granulomatous hepatitis. Positron emission tomography scan showed extensive hepatic uptake, diffuse lymphadenopathy, as well as numerous fluorodeoxyglucose-avid osseous lesions. After extensive workup to rule out malignancy and infectious etiologies, a diagnosis of diffuse multi-organ sarcoidosis was made. He was ultimately treated with methotrexate and steroids, resulting in marked improvement in symptoms and liver function, with stable disease on repeat imaging. Conclusion. Diffuse multi-organ sarcoidosis is often associated with widespread lymphadenopathy and osseous lesions, which appear indistinguishable from malignancy on imaging. The angiotensin converting enzyme levels and inflammatory markers may be normal. Clinicians should be aware of the possibility of diffuse systemic sarcoidosis in any patient with a remote sarcoidosis history and the simultaneous development of multi-organ–related symptoms.
