Case Discussion

This is a case of the angiographic spot sign, which may indicate active hemorrhage.

The patient was admitted to the neurological intensive care unit where his course was complicated by worsening mental status, multiple failed videofluoroscopic swallowing studies, and MSSA pneumonia. After some time, the patient began to improve and was admitted to the stepdown unit and, eventually, to a rehabilitation facility.
