Hematuria in the ER patient: optimizing detection of upper tract urothelial - A pictorial essay.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.

The Utility of Cardiac Computed Tomographic Angiography in Differentiating Between Papillary Fibroelastoma, Infective Endocarditis, and Degeneration of the Aortic Valve.

Purpose: Cardiac computed tomography angiography (CCTA) has significantly advanced the visualization of cardiac structures, particularly valves. We assessed the diagnostic performance of CCTA in diagnosing the most common disorders affecting the aortic valves requiring surgery-papillary fibroelastoma, infective endocarditis, and degeneration.

Methods: This retrospective study included patients who underwent aortic valve resection between 2016 and 2023 and had a preceding CCTA.

Cinematic rendering of pleural solitary fibrous tumor.

Solitary fibrous tumors are rare and typically benign fibroblastic neoplasms with a mean age of onset ranging from 60 to 70 years. Solitary fibrous tumors may arise anywhere within the body, however the pleura is the most common site of origin for these tumors, with approximately 30% of tumors arising from the pleura. In this report we highlight the case of a 62-year-old woman who presented with gradually progressive left sided chest pain that was eventually diagnosed as a pleural SFT.

Nodular expression of seminoma in the neck: An unusual case presentation.

Seminoma is a malignant germ cell tumor that primarily develops in the testis but can occur in other extragonadal areas, most commonly the mediastinum and retroperitoneum. While generally offering a favorable prognosis, seminomas can sometimes clinically present with misleading characteristics resulting in delayed diagnosis. In this article, we report the case of a 31-year-old male diagnosed with grade IIIC intermediate risk testicular seminoma cTxN3M1bSx, who presented initially with a palpable cervical mass.
