Intraparenchymal Brain Abscess in an Adult Male With Underlying Ebstein Anomaly and Cor Triatriatum Dexter.

A 21-year-old man presented with new-onset seizures and brain abscess. Echocardiography and cardiac magnetic resonance imaging revealed underlying Ebstein anomaly, secundum atrial septal defect, and cor triatriatum dexter. The elevated right heart pressures shunting through the septal defect and transient bacteremia were the likely mechanisms for his presentation. (Level of Difficulty: Intermediate.).

Multiple organ dysfunction syndrome and death secondary to Cyberlindnera fabianii.

Cyberlindnera fabianii is a yeast present in soil rarely associated with invasive infection. Due to advanced diagnostic and therapeutic techniques, pathogenicity is increasingly recognized. A 37-year-old male with B cell lymphoma on rituximab developed multiple organ dysfunction syndrome secondary to C. fabianii bacteremia. Specialized species identification techniques were required after failure of standard methods. Despite extracroporeal membrane oxygenation (ECMO) the patient died on day 26 after admission.
