ABSTRACT
Cemento-ossifying fi broma is a benign rare tumor of mesenchymal origin seen in the third or fourth decade in females. It arises from the mesenchymal blast cells of the periodontal ligament and can mature into cementum, bone, or fi brous tissue or varying proportions of each. Th e lesion is most commonly seen in the jaw. It appears as a well-defi ned circumscribed unilocular radiolucent lesion. Radio-opacity of the lesion depends on the concentration of cement or bone or in the concentration of both. We present the imaging features of cemento-ossifying fi broma in a 73-year-old female patient, involving the left maxilla.
ABSTRACT
Urological pathologies especially stricture urethra are a cause of significant morbidity and hence radiological evaluation of the same is of prime importance to determine the treatment protocol for each disease. A retrospective analysis of the conventional radiographic imaging findings of traumatic and nontraumatic lower urinary tract pathologies was done over a period of 5 years, and the case spectrum included urethral and bladder diverticulum, urethritis, posterior urethral valves, and fistulas (including urethra - perineal, rectourethral and vesicovaginal fistulas). The rarer nontraumatic pathologies were prostatic utricles, urethral polyps, bladder neck obstruction, hypospadias, anterior urethral valve, vesical calculus, etc., The traumatic case spectrum included cases of urethral injuries and intra/extraperitoneal bladder rupture. This pictorial assay reviews the need of retrograde urethrogram–micturating cystourethrogram for the evaluation of the anterior urethral, posterior urethral and bladder pathologies (traumatic and nontraumatic) and also describes each pathology with respect to etiology, diagnosis and imaging findings.
