Nocardiosis is an uncommon infection, however it needs to be included in the differential diagnosis, especially in immunocompromised hosts. Central nervous system (CNS) nocardiosis, in particular, is an even rarer entity with a higher mortality. This is a case of CNS Nocardia infection with an atypical presentation that was initially concerning for metastatic disease. In an immunocompromised patient with CNS findings, atypical infectious processes need to be considered. In a patient with concomitant pulmonary findings, an evaluation for Nocardia should be pursued as the lungs are the primary route of entry for this organism. Treatment typically involves a sulfonamide with secondary antibiotic agent, however a combination using meropenem has proved effective here.
Purpura fulminans (PF) is a rapidly fatal disorder predominantly encountered in patients with an acquired deficiency of physiologic anticoagulants due to severe sepsis and septic shock with disseminated intravascular coagulation (DIC). This consumptive process eventually leads to widespread thrombosis, hemorrhagic necrosis, and gangrene. Rapid identification followed by aggressive management of the underlying etiology with a multidisciplinary team is critical to prevent long-term organ dysfunction, disability from amputation, and death. While bleeding is a common finding in DIC, anticoagulation must be considered if PF is present. We report a case of Escherichia coli-associated emphysematous pyelitis leading to bacteremia, septic shock, and PF with small-and medium-sized vessel thrombosis and acral ischemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
