Disseminated cryptococcosis with adrenal and lung involvement in an immunocompetent patient

Diffuse Adrenal Gland and Pancreas Necrosis in a Patient with Disseminated Cryptococcosis-Case Report

(1) Background: Cryptococcus neoformans is mostly known for causing meningitis, with or without disseminated disease. (2) Case presentation: An immunocompromised 75-year-old gentleman presented post renal transplant with generalized weakness, altered mental status, hypoxemia, and hyponatremia, and was found to have disseminated cryptococcal infection. After an initial improvement, the patient became suddenly hypotensive, and passed away soon after. The autopsy revealed widespread cryptococcal involvement, with the most severely affected organs being the brain, lungs, pancreas, adrenal glands, and spleen. The pancreas and one of the adrenal glands revealed diffuse granulomatous cryptococcal infection, with large areas of necrosis. The spleen also showed a large area of cryptococcal necrosis. In addition, the patient had chylous ascites, without histologically identifiable organisms. (3) Conclusions: This is a rare case of disseminated cryptococcal infection with severe necrotizing adrenalitis and pancreatitis, in addition to significant spleen, lung, and central nervous system involvement. The early recognition and treatment of the adrenal gland and pancreas cryptococcosis with surgical interventions may lead to better outcomes in affected patients. Furthermore, steroid treatment and diabetes mellitus may be risk factors for adrenal gland involvement. Additionally, clinicians should keep cryptococcal infection in their differential diagnosis for isolated adrenal gland and pancreas lesions.

Normalization of Bilateral Adrenal Gland Enlargement after Treatment for Cryptococcosis

Cryptococcosis usually occurs in immunocompromised patients and can cause enlargement of the adrenal glands, although the morphologic changes after treatment have not been reported in detail. We report the case of 24-year-old man with fevers, headaches, and impaired consciousness who had been treated with glucocorticoids for a protein-losing gastroenteropathy. The cerebrospinal fluid analysis revealed cryptococcal meningitis. Computed tomography showed bilateral adrenal enlargement. A retrospective analysis revealed that the enlargement had been detected 5 months before admission and gradually increased. The enlargement was improved with antifungal therapy and normalized 6 months later. This is the first report describing morphological changes in the adrenal glands associated with cryptococcal meningitis. Adrenal enlargement by cryptococcosis can be improved without any abnormal findings, including calcifications, which may be a unique characteristic from other diseases, including tuberculosis.

Disseminated Cryptococcosis with Adrenal Insufficiency and Meningitis in an Immunocompetent Individual

We present a case of cryptococcosis with adrenal insufficiency and meningitis in a healthy host without any risk factors. Antifungal therapy did not reduce the cryptococcal antigen titers of the cerebrospinal fluid and serum or the bilateral adrenal gland enlargement. It was suggested that the adrenal glands were the focus of persistent fungemia. Removal of both adrenal glands brought about a response to antifungal therapy. We conclude that if antifungal therapy is ineffective, bilateral adrenalectomy is an effective measure for treatment of such patients. Cryptococcosis is a possible cause of primary adrenal insufficiency in immunocompetent patients.
