RT Journal Article SR Electronic T1 Overwhelming cryptococcosis complicated by cryptococcal endocarditis JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e247310 DO 10.1136/bcr-2021-247310 VO 15 IS 3 A1 Elkhatib, Wiaam A1 Kwon, Joshua Y A1 Phillips, Michael B YR 2022 UL http://casereports.bmj.com/content/15/3/e247310.abstract AB Cryptococcal species endocarditis is infrequently described, carries high mortality and nearly always occurs in immunocompromised states or on prosthetic valves. We report the case of a man in his 70s with multiple recent hospitalisations for pneumonia, hypercalcaemia and septic tank exposure who presented with intermittent fevers, progressive weakness,and worsening encephalopathy, manifested as confusion and word-finding difficulties for 3 weeks. Workup revealed cryptococcal species on blood serum gram stain, native aortic valve endocarditis and meningitis. Cerebrospinal fluid analysis demonstrated lymphocytosis, ultimately found to be secondary to chronic lymphocytic leukaemia. Surgical valve replacement was deemed medically contraindicated and antifungal therapy was initiated. Though poorly understood with very few documented cases, management of cryptococcal endocarditis relies on prompt diagnosis, early surgery when indicated, long-term antifungal therapy and treatment of underlying immunocompromising states where possible.
