A case of continuous-type splenogonadal fusion

Abstract

Splenogonadal fusion is a rare developmental anomaly in which an abnormal connection between the splenic tissue and gonads or mesonephric derivatives is present. Less than 200 cases have been reported since it was first described in 1883. Preoperative misdiagnosis is common and may lead to unnecessary orchidectomy if testicular neoplasm is suspected. To avoid such outcomes, it is important to be aware of the features of splenogonadal fusion. We report the case of a five-month-old male infant with continuous-type, left-sided splenogonadal fusion, which was discovered during groin exploration for a scrotal mass. Although the lesion was first noted during an episode of nonspecific viral fever, such an association is uncommon. Preoperative ultrasonographic evaluation favoured a diagnosis of a large haemangioma. This is the first reported case of splenogonadal fusion from Sri Lanka.
