SPLENOGONADAL FUSION DIAGNOSED BY SPLEEN SCINTIGRAPHY

Splenogonadal fusion (SGF) is a rare congenital malformation character ized by fusion of the spleen and a gonad (almost always the left one) frequently associated with orofacial and/or limb developmental abnorma lities, Only 125 cases were reported between 1883 and 1994. This repor t concerns a case of SGF in a 20-yr-old woman with an accidental findi ng of a splenic space-occupying lesion protruding into the lower abdom en in ultrasound and CT, Radiocolloid spleen scintigraphy and SPECT pr oved to be the best procedure to establish the correct diagnosis of SG F, As SGF is often asymptomatic, more liberal use of splenic scintigra phy is suggested in patients with congenital limb and/or orofacial ano malies. SGF should be included among the differential diagnoses of lef t abdominal, pelvic or scrotal masses.
