Abstract

Spontaneous regression of intra-abdominal cystic tumors in adults is unusual. Here, we present the case of an apparently spontaneous regression of a large intra-abdominal cystic mass found in the postpartum period of an 18-year-old woman. The regression was demonstrated using serial computed tomography (CT) examinations over a two-year period.

Figure

• 

  Fig. 1 Coronal (A) and axial (B) view of contrast enhanced CT scan demonstrating a large, multilobulated, multilocular, heterogeneous cystic mass with internal septa in the right upper quadrant abdomen. On axial T2-weighted spin echo image (8000/105) with fat suppression (C) and axial T1-weighted incoherent gradient-echo (SPGR) images (230/4.2) (D), the signal intensity of the upper portions of the fluid within the cysts showed high signal intensity, and the area of the lower portions of fluid showed low signal intensity.

• 

  Fig. 2 Follow-up CT scan two years after initial examination shows marked regression of the mass with a tiny remaining cystic lesion in the right upper quadrant abdomen.
