We present 2 elderly patients who developed lung infiltrates associated with eosinophilia during intravenous daptomycin treatment. Both patients improved quickly after daptomycin was stopped and steroid treatment was initiated. However, complete recovery did not occur, and both patients became chronically steroid dependent.

Transesophageal echocardiography (TEE) is a commonly used procedure in patients with suspected endocarditis. A rare but dreadful complication of this procedure is perforation of the esophagus. We report the case of an elderly female with multiple comorbidities, who presented with polyarticular septic arthritis. TEE was performed to rule out endocarditis. Though the standard procedure protocol was followed, she developed esophageal perforation. It was managed with esophageal stenting but she developed multiorgan failure and did not survive. This case highlights the potential of severe morbidity and mortality associated with TEE. Appropriate screening must be done and high-risk individuals must be identified before such procedures are attempted.

Murine typhus is an endemic infectious disease caused by Rickettsia typhi and is transmitted by fleas. It typically causes a mild illness with symptoms of fever, rash, headache, chills, and non-specific gastrointestinal complaints. However, there have been no reported cases in the literature of murine typhus infection causing symptoms of acute psychosis and disseminated intravascular coagulation (DIC). A 30-year-old female with a history of gastric bypass and chronic pain syndrome presented to the emergency department with altered mental state and fever. She developed vivid visual hallucinations, DIC, and hypoxia with pulmonary opacities, ultimately requiring intubation. Magnetic resonance imaging (MRI) showed leptomeningeal enhancement with unremarkable cerebrospinal fluid (CSF) studies. Serum murine typhus serology came back positive. Doxycycline therapy was initiated, which resulted in complete patient recovery. This case shows that murine typhus infection may present with acute psychosis and can mimic DIC, leading to diagnostic confusion. MRI sequences may show leptomeningeal enhancement, which has never been reported before in patients with typhus. Early neurological imaging using advanced MRI sequences for patients presenting with altered sensorium, visual hallucinations, and symptoms similar to thrombotic thrombocytopenic purpura (TTP) may help with early diagnosis, decreased hospital stay, and better prognosis.
