Post-trauma inguinal seroma formation in the cat

Seven cats presented with large caudoventral abdominal or inguinal swellings following road traffic accidents. No case had evidence of disruption to the body wall or inguinal ring and the inguinal swellings may have been the result of either shear or compressive injury to soft tissues of the inguinum or disruption of the regional lymphatics. Six cases resolved completely following strict rest or simple Penrose drain placement with no recurrence reported. Recurrence of seroma was seen in one case but which then fully resolved following omentalisation of the inguinum.
