title: Panda sign due to severe coughing.
abstract: We present the case of a patient who developed periorbital ecchymosis (panda sign) following an exacerbation of asthma with severe coughing. There was no history of cranial trauma. Investigations for a structural or haematological cause were negative. The panda sign is typically seen following a base of skull fracture, but rarely reported due to severe coughing.
