Following the bite of Philodryas olfersii latirostris Cope, 1862, a 29-year-old male herpetologist developed localized and burning pain, and minimal bleeding from the puncture marks of posterior maxillary teeth, which subsided rapidly. The victim developed no other local signs or symptoms. After few days the victim presented persistent severe rotatory dizziness, nausea, and vomiting. On examination his hearing was normal. Neurological exam was otherwise normal. The patient had acute vertiginous symptoms but had no associated neurological signs. Computed tomography did not show abnormality. A diagnosis of labyrinthine syndrome was made. It was treated conservatively, and the patient recovered uneventfully. It was assumed as an effect of ophitoxemia. This case may be regarded as an unusual presentation of systemic envenoming following a human bite by Philodryas olfersii latirostris.
