Diagnostic imaging of injuries caused by venomous and traumatogenic catfish

Abstract

Injuries caused by fi sh are common in marine and freshwater environments. Catfi sh of the Ariidae and Pimelodidae families cause about 80% of those injuries. One of the complications of injuries caused by fi sh is the retention of fragments of the stinger in the wounds. Here we report fi ve cases (of a total of 127 injuries caused by catfi sh in the Brazilian coast) in which the retained fragments were detected by radiological examination. Retained fragments should be considered in patients stung by catfi sh. A simple X-ray is suffi cient to detect fragments of stingers in the wounds.

Catfish spine injury to the hand with transient lymphangitis

“…Imaging can identify catfish spines. Plain radiographs often are sufficient and have been reported to have high sensitivity in identifying catfish spines 14. CT and MRI have been used in more complicated cases 6.…”

“…CT and MRI have been used in more complicated cases 6. Ultrasound may have a role in identifying catfish spines 14. Ajmal described a case in which plain radiographs were not obtained and a retained spine fragment led to the patient presenting with swelling and infection 13 months after the initial injury 13…”
