Successful Treatment of Pulmonary Cryptococcosis in a Liver Transplant Recipient Before and After Liver Transplant: Case Report and Literature Review.

Cryptococcosis is the third most common invasive fungal infection in solid-organ transplant recipients. Patients with cirrhosis are susceptible to pretransplant cryptococcosis infections. Outcomes and optimal treatment of patients with cirrhosis who develop pulmonary cryptococcosis before and after liver transplant are still not defined. Here, we describe a case of cholestatic cirrhosis in a 50-year-old woman with a pretransplant asymptomatic pulmonary nodule. She had taken steroids for more than 1 year before she was admitted to our hospital. This asymptomatic case with a lung nodule was detected via an abnormal chest computed tomography. Cryptococcal pneumonia was diagnosed according to lung biopsy results. Testing for cryptococcal antigens was negative in the serum. The patient received antifungal therapy with amphotericin B followed by oral fluconazole, which was then followed by liver transplant. After antifungal therapy with fluconazole posttransplant, a sustained clinical response was achieved. After literature review of patients with pulmonary cryptococcosis before and after liver transplant, we identified previously reported cases with pulmonary cryptococcosis that resembled lung nodule on imaging. In this report, we aimed to raise the awareness of unrecognized pretransplant cryptococ-cosis infections in patients with cirrhosis who are waiting for liver transplant and showed the successful management of a patient with pretransplant pulmonary cryptococcosis.
