Torsion of a wandering spleen with whorled appearance of the splenic hilum in CT scan.

An eight-year-old boy admitted for acute abdominal pain was diagnosed to have torsion of the spleen (TS) based on contrast enhanced computerised tomography (CECT) of the abdomen. CECT showed whorled appearance in the splenic hilum. Whorl sign' refers to the presence of a twisted splenic pedicle intermingled with fat, resulting in alternating circular bands of radiodensity and radiolucency and is considered diagnostic of TS. This is the fourth reported case of whorl sign in children with TS and the first from Malaysia.
