A CT scan of her abdomen and pelvis was obtained, which demonstrated a 5.3 x 8.8 x 12.6 cm rim-enhancing, loculated soft-tissue mass extending from the anterior dome of the bladder to the lower anterior abdominal wall and invading the rectus abdominis muscles, concerning for urachal carcinoma vs. urachal cyst abscess (Figure 1).
Ultrasonography of the upper pelvis, transverse (left) and sagittal (right) views. The heterogeneous mass (arrows) lies superficial to the bladder, which is decompressed with a Foley catheter.

Ultrasonography further characterized the mass as heterogeneous with both cystic and solid components, and revealed that there was not a drainable pocket (Figure 2).
CT scan (left) and Ultrasound (right) of the pelvis. These studies demonstrate a smaller, heterogeneous mass (arrows) with a solid superior compartment and a walled-off, phlegmon-filled inferior compartment.

More distinct regions were seen within the mass; the superior aspect had the heterogeneous appearance of a solid tumor with central liquefactive necrosis while the inferior region was consistent with a mature abscess (Figure 3).
