Sarcoidosis is a multisystemic disorder of unknown cause that is characterized pathologically by noncaseating granulomas. Diagnosis is based on the exclusion of other infectious, interstitial, and neoplastic diseases and on the typical pathology. Although the lungs and mediastinal lymph nodes are almost involved, endobronchial nodular lesions of sarcoidosis with lung involvements are rare. We report a case of sarcoidosis with lung involvements and endobronchial nodules as confirmed by bronchial biopsy.
Invasive aspergillosis typically occurs in immunocompromised patients and results in fatal complications. Musculoskeletal involvement of aspergillosis is extremely rare, therefore, when it occurs, its diagnosis and treatment could be delayed. In this paper, we report a rare case of primary invasive aspergillosis with radiologic findings in a patient with rheumatoid arthritis. A 57-yearold woman presented a palpable mass on the right hand with a previous medical history of long-term use of immunosuppressive agents due to rheumatoid arthritis. Magnetic resonance imaging showed a multilobulated and multiloculated cystic lesion with an enhancing wall. The wall of the cystic lesion showed low signal intensity on T2 weighted images and intermediate to high signal intensity on T1 weighted images. The mass was confirmed as chronic granulomatous inflammation with multiple acute branching and septated fungal hyphae, consistent with invasive aspergillosis. When a superficial multicystic mass in the hand of especially immunocompromised patients is encountered, invasive aspergillosis should be included in the differential diagnosis, although it is rare.
A 57-year-old woman with no significant past medical history and normal immunity presented with a slowly growing mass on her finger. MR imaging showed a low signal intensity soft tissue mass on both T1-and T2-weighted images with peripheral contrast enhancement. The mass was diagnosed as chronic granulomatous inflammation with caseous necrosis histopathologically and also Mycobacterium tuberculosis by a polymerase chain reaction about the tissue specimen. Authors thought that it was tuberculous gumma presented in an immunocompetent patient. This paper reports a rare case of tuberculous gumma with radiologic findings in an immunocompetent patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
