Bilateral parotid enlargement following snake bite: A rare sign

Bilateral Parotid Enlargement Following Hematotoxic Snake Bite: A Unusual Sequelae of the Venomous Sting

“…4 Bilateral parotid swelling is an unusual clinical feature of viper bite. A similar case of bilateral parotid swelling after Russel viper bite was reported by Chakraborty et al and Deepak et al 2,5 Their patient developed parotid swelling about 8 hours and 6 hours after snake bite respectively.…”

Our patient travelled 25 km from his village to a local hospital where he was treated with four vials of antivenom and was then shifted to our hospital, which is another 45 km.…”

“…Viper envenomation presentation varies from minor localized signs to life threatening systemic manifestations in up to 92% of cases, as Russell's viper is both a large and highly aggressive snake . Apart from unusual complications such as ventricular tachycardia, myocardial infarction, and hypopituitarism , there is evidence that bilateral parotid swelling may occur and is associated with poor prognosis .
