Postinfectious COVID-19 Catatonia: A Report of Two Cases.

Neuropsychiatric symptoms are a common complication of COVID-19, with symptoms documented both during acute COVID-19 infection (parainfectious) and persisting or developing after the resolution of respiratory symptoms (postinfectious). Patients have presented with a variety of symptoms such as anosmia, thrombotic events, seizures, cognitive and attention deficits, new-onset anxiety, depression, psychosis, and rarely catatonia. Etiology appears to be related to disruption of regular neurotransmission and hypoxic injury secondary to systemic inflammation and cytokine storm.

A Giant Left Intraventricular Thrombus Associated With Apical Hypertrophic Cardiomyopathy Mimics Cancer.

Hypertrophic cardiomyopathy (HCM) is a common disease that can be acquired due to chronic hypertension or via autosomal dominant inheritance. Several patterns of HCM have been described, of which a rare variant is apical hypertrophic cardiomyopathy (AHCM). Atrial thrombus is a well-recognized complication of HCM especially in the setting of atrial fibrillation (AF).
