A Case of Steroid-Responsive Severe Pneumonia Following a Recent COVID-19 Infection in a Patient With Pediatric Autoimmune Neuropsychiatric Disorders Associated With Streptococcal Infection.

A twenty-two-year-old woman with a history of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) on rituximab presented with fever, abdominal pain, and worsening shortness of breath requiring supplemental oxygen via nasal cannula one month after a severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection from which she was minimally symptomatic and had recovered. Radiographic studies revealed bilateral patchy consolidations interspersed with ground-glass opacities (GGO). She was started on antibiotics for presumed community-acquired pneumonia with no improvement.

An Unusual Case of Posterior Reversible Encephalopathy Syndrome.

A 21-year-old pregnant female with no significant past medical history presented with acute onset headache and nausea as well as tonic-clonic seizures, then rapidly decompensated into a coma with complete absence of brainstem reflexes. The patient was ultimately diagnosed with hemolysis, elevated liver enzymes, and low platelets (HELLP syndrome) and subsequent posterior reversible encephalopathy syndrome (PRES) with brainstem involvement. Emergent delivery and blood pressure control resulted in rapid and complete neurologic recovery.
