Coronary circulation anomalies are the uncommon cause of chest pain when hemodynamically significant. Multidetector computed tomography (CT) of coronary arteries is rapidly replacing conventional angiography, nowadays, as the first line of investigation for the imaging of coronary artery disease due to its noninvasive nature. CT coronary angiography in addition to diagnosing anomalies of coronary arteries is especially good in the delineation of ostial origin and proximal course. Superdominant right coronary artery (RCA) with absent left circumflex artery (LCx) is such a rare congenital coronary artery anomaly which can mimic atherosclerotic disease clinically with very few case reports in the literature which can be diagnosed and evaluated with accuracy by CT angiography.

Renal replacement lipomatosis also known as fibrolipomatosis is a rare chronic pathological condition of the kidney characterized by atrophy and damage to renal parenchyma with excessive proliferation of fat beginning from renal sinus and gradually replacing entire kidney by a fatty pseudotumor. We are presenting a case report of renal replacement lipomatosis in an elderly male with the long-term history of renal stones and coexistent psoas abscess on imaging mimicking as xanthogranulomatous pyelonephritis. Role of (computed tomography) CT imaging is described as preferred modality of investigation to describe unique features of this disease, to differentiate it from xanthogranulomatous pyelonephritis and as a roadmap to surgery.

A 32-year-old female presented with complaints of recurrent urinary tract infections, tender vaginal swelling and painful intercourse. She underwent repeated aspirations of anterior vaginal wall swelling by gynecologist considering it as primary vaginal cyst but the swelling was recurrent after short course of time. MRI imaging of pelvis was performed after the opinion of urologist considering the possibility of the infected urethral diverticulum. MRI examination revealed multiloculated fluid containing lesion around urethra appearing like saddle bag and spoke wheel on axial images and mimicking like enlarged prostate on sagittal images with submucosal enhancement and diffusion restriction of contents suggesting infected urethral diverticulum. Objective: We are discussing role of MRI imaging with the help of radiological signs in the accurate diagnosis of urethral diverticula in symptomatic patients to avoid painful and complicated interventional imaging procedures and narrow down the possibility of alternate diseases in the same territory.
