Which imaging modalities may be used to evaluate a suspected pelvic mass causing bladder compression in interstitial cystitis?

• A. EEG
• B. MRI, CT, and pelvic ultrasound
• C. Chest X-ray
• D. Angiography

Answer: (B)

When a pelvic mass is suspected to compress the bladder, you want imaging that identifies the mass, reveals its origin, and shows how it sits in relation to the bladder and nearby organs. Pelvic ultrasound is usually the first step because it’s readily available, safe, and can determine whether the lesion comes from the ovaries, uterus, or bladder and how it displaces or compresses the bladder. If more detail is needed to characterize tissue and exact origin, MRI provides superior soft-tissue contrast and multiplanar views to map the mass’s relationship to surrounding structures. CT adds rapid, broad cross-sectional assessment of the pelvis and abdomen, useful for evaluating extent, calcifications, and adjacent organ involvement, especially when MRI isn’t feasible or when a quick overall survey is required. Together, these modalities cover the common imaging approaches for evaluating a suspected pelvic mass causing bladder compression. EEG, chest X-ray, and angiography aren’t chosen for this purpose in the typical workup.
