A 56-year old man, originally from Pakistan, presented with bilateral avascular necrosis of the hips on a background of emphysema, pulmonary fibrosis, coronary artery disease, diabetes type 2 and psoriasis. The cause of the avascular necrosis was unclear, with no recent trauma or steroid use. During his preoperative consultation, he presented dysautonomia requiring an inpatient investigation; the surgery was canceled. He reported a thirty-pound weight loss and a three-week history of night sweats and shortness of breath. While hospitalized, this gentleman presented subacute confusion and fluctuation of his sensorium, compatible with limbic encephalitis. Furthermore, he developed diffuse myokymia involving the axial and appendicular musculature, confirmed by EMG.
