Aphasia hemiplegia with abdominal pain in a female patient caused by Staphylococcus lugdunensis infection: a case report

Abstract

Objective: to describe the clinical features of a case of infective endocarditis caused by Staphylococcus lugdunensis, followed by cerebral embolism, spleen embolism and tendon rupture. Methods: the clinical data of a 22-year-old female patient with aphasia hemiplegia and abdominal pain were collected. Relevant examinations such as routine blood test, myocardial enzyme spectrum, electrocardiogram (ECG), cardiac color Doppler ultrasound, brain magnetic resonance, abdominal computed tomography (CT) and blood culture were completed, and anti infection treatment was carried out according to the drug sensitivity test. Results: brain magnetic resonance imaging (MRI) showed cerebral infarction in the left basal ganglia, cardiac color Doppler ultrasound showed mitral valve vegetation and abscess formation, and abdominal CT showed splenic infarction. After anti infection treatment, the patient’s condition gradually improved, but the patient had sudden arrhythmia in the recovery period. Color Doppler ultrasound showed rupture of the mitral tendinous cord and valve prolapse. The condition was improved after surgical treatment. Conclusion: the first manifestation of Staphylococcus lugdunensis infection is cerebral infarction, which is relatively rare in the clinic setting. The main manifestation of this case is aphasia hemiplegia with abdominal pain. Blood culture and identification show Staphylococcus lugdunensis, which is rare in adolescent patients. The infection has a rapid onset, rapid progress and causes serious valve damage. Timely strain identification and drug sensitivity test are conducive to accurate diagnosis and treatment. Valve surgery is often necessary.
