Catatonia is a psychomotor syndrome predominantly associated with mental illness disorders, most commonly bipolar disorder and schizophrenia. Catatonia is classified as malignant when, in addition to catatonic symptoms, dysautonomia is present. Autonomic abnormalities can include changes in temperature, labile blood pressure, and changes in heart and respiratory rates. Because malignant catatonia is life-threatening, prompt recognition and management are essential to prevent mortality. We present a severe case of catatonia with malignant features that highlight the importance of early diagnosis and treatment.
