Low-Grade Urachal Cystadenoma With Abundant Calcification Removed Using Robot-Assisted Laparoscopy: A Case Report

Andrew P Kochvar et al. Cureus. .

Abstract

Neoplasms of the urachus are an extremely rare entity consisting of incompletely obliterated tissue of the urachal canal during embryonic development, which sometimes remains into adulthood in the urinary bladder. The treatment of choice for these entities is surgical excision, which maximizes patient survival should the lesion prove to be malignant. In this case, we describe a 57-year-old female who presented with a one-year history of left lower quadrant pain. The patient underwent robot-assisted surgery to remove the mass, bladder dome, and median longitudinal ligament en bloc without evidence of recurrence to date.

Keywords: abdominal radiology; robotic surgical procedures; urachal cancer; urachal cystadenoma; uro-oncology; urology.

Figure 1. Bladder US in transverse (A) and long (B & C) views demonstrating a well-circumscribed complex cystic lesion attached to the bladder dome. No vascularity is demonstrated within the lesion flow Doppler images (C).
Figure 2
Figure 2. MRI pelvis with and without IV contrast demonstrates the well-circumscribed, multiloculated mass (*)
A and B show sagittal sections of T1-weighted fat-saturated post-contrast images of the T1 hypointense lesion (*), demonstrating thickened nodular walls and enhancement in the posteroinferior aspect. T1 fat saturation without contrast axial section (C) demonstrates T1 hyperintensities. D and E show T2-weighted images, which emphasize the mildly heterogeneous, predominantly high T2 signal cystic lesion, focal areas of low T2 signal, and multiple low-signal septations.

Figure 3. CT chest abdomen and pelvis sagittal (A), coronal (B), and axial (C) slices where the lesion can be visualized
The images demonstrate a heterogeneous complex cystic mass lesion (*) with multiple focal hyperdensities and contrast enhancement most prominent at the anterior bladder dome.
