Case Study

Introduction Invasive aspergillosis is a life-threatening , opportunistic infection that occurs most often in immunocompromised patients . Myocardial abscess is a rare and potentially fatal condition . Metastatic myocardial abscess , in the setting of infective endocarditis , has been infrequently reported . Herein , we report a case of disseminated aspergillus infection with vertebral body osteomyelitis , renal aspergillosis , myocardial abscess , and endocarditis in a liver-transplant patient . A high index of clinical suspicion is required to make a prompt diagnosis . Final diagnosis may need a combination of serological tests and imaging , particularly in instances where biopsy is non-yielding or cannot be performed .

Disseminated Aspergillus of the Heart : A Case Report of Intracavitary , Myocardial , and Valvular Fungal Involvement

Case Description A 64-year-old female underwent liver transplantation for fulminant Hepatitis A liver failure six months earlier . She presented to the hospital with pain radiating down her right lower extremity . She complained of chronic lumbosacral back pain that had persisted ever since her transplant , however progressively worsened . She denied any numbness , tingling , or loss of sensation . MRI of the spine was ordered , which revealed osteomyelitis and discitis of L2 / 3 with an epidural phlegmon ( Figure 1 ). Incidentally , she was found to have a new hypodense right kidney lesion ( Figure 2 ). Biopsy of the epidural phlegmon and right kidney lesion revealed aspergillus ( Figure 3 ). Serum aspergillus
galactomannan antigen was positive at that time . She was started on Amphotericin B and eventually transitioned to Isavuconazole as her QT prolongation on EKG did not allow for Voriconazole . Chest CT performed for new onset hypoxia revealed a filling defect in the left atrium ( Figure 4 ) and an additional low density myocardial mass arising from the free wall of the left ventricle felt to represent a myocardi-
