From flank pain to splenic abscess: a complex case of infective endocarditis with literature review

Abstract

Background: Infective endocarditis (IE) is a severe condition characterized by inflammation of the heart endocardium and valves, commonly caused by Gram-positive bacteria. Complications such as embolic phenomena and organ abscesses can arise, necessitating timely diagnosis and intervention. Case presentation: We report the case of a 20-year-old female with a history of cerebral and splenic infarctions due to IE. The patient presented with left-sided flank pain, urinary burning, and fever. Examination revealed mitral and aortic valve involvement, splenomegaly, and neurological deficits. Despite initial antibiotic therapy, the patient developed a splenic abscess and drug-induced neutropenia. She required aortic valve replacement and was successfully managed with a multidisciplinary approach. Conclusion: Multidisciplinary management, including timely surgical intervention and advanced imaging, is essential for favorable outcomes in IE patients. This case underscores the importance of early detection and tailored treatment strategies in managing severe complications associated with IE.
