Abstract:
We report the clinical, radiologic, and pathologic findings of a case of inflammatory pseudotumor in an otherwise healthy 44-year-old woman, who presented with dysuria and hematuria causing hemodynamic instability. Computed tomography revealed a 4.3-cm by 3.5-cm densely enhancing mass arising from the anterior bladder wall. Pathologic examination showed spindle-shaped cells with mild nuclear pleomorphism, rare mitotic activity, and a strong reaction to vimentin, with focal positivity to alpha-actin and S100 protein. Monokeratin, CK7, and CK20 were negative. After two transurethral resections, the patient underwent partial cystectomy.

Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
