An Unusual Presentation of Neurosarcoidosis in a 64-Year-Old Man: A Case Report.

Sarcoidosis is a multisystem granulomatous disorder with an unknown etiology that typically involves the lungs, skin, and lymph nodes, with neurological involvement being relatively rare. We discuss a case of neurosarcoidosis in a 64-year-old man who initially presented with unexplained cognitive impairment, insomnia, hyponatremia, paresthesias, and weight loss and later developed uveitis, diplopia, and dysphagia. Ultimately, findings of hilar and mediastinal lymphadenopathy on chest computed tomography (CT) resulted in bronchoscopy, which led to the diagnosis.

The Clinical Course of a Severe Case of Malignant Catatonia.

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.
