RESUMO

Hemophilic pseudotumor (HP) is a rarely encountered cystic mass that forms as a result of repeated bleeding from extra-articular soft tissues. HP cases have been previously documented in several locations in the body, most commonly in the femur and pelvis. To date, no upper extremity case involving the bilateral forearms has been reported. The current case involves an adult male with uncontrolled hemophilia who presented with diffuse enlargement of the bilateral forearms with associated pain. Radiographs and magnetic resonance imaging (MRI) were subsequently performed revealing variable aged hemorrhagic, expansile, lytic intramedullary lesions. In keeping with the history, a subsequent radiologic diagnosis of HP was favored, among other differentials, including benign and malignant processes with biopsy confirming the diagnosis. The hemorrhagic masses were surgically excised after initial management with factor VIII replacement. This case details a unique presentation of this pathology in the bilateral forearms and highlights the diagnostic value of radiographs and MRI in diagnosis and management.

RESUMO

With the rapid spread of coronavirus disease 2019 (COVID-19) starting in early 2020, there has been much interest in the applicability of radiologic imaging in managing affected patients. From the initial screening to addressing the extent of pulmonary involvement, CT scans provide great value to hospitals overwhelmed by an influx of patients, including those with suspected COVID-19. Because CTs come at a high financial cost, lower cost real-time polymerase chain reaction (RT-PCR) COVID-19 tests are critical due to their ability to identify asymptomatic carriers and properly handle patients during the ongoing pandemic. However, unlike RT-PCR, CT scans can also provide insight into the progression of the virus. The signs of acute COVID-19 infection include unique patterns of ground-glass opacities (GGO) with vascular thickening, enabling radiologists to diagnose COVID-19 with a high specificity. Additionally, there may be a significant value in the use of CT scans in predicting the outcomes.

RESUMO

Fibroepithelial lesions of the breast are commonly encountered tumors comprised of stromal and epithelial components. Fibroadenoma and phyllodes tumor are both fibroepithelial lesions, but their management differs. Phyllodes tumor requires surgical excision, whereas fibroadenoma requires no further workup. Both have many overlapping histological features making it difficult to distinguish between a benign fibroadenoma versus the more aggressive phyllodes tumor. This case details a breast mass that was initially believed to be a fibroadenoma, but interval growth at one year follow up resulted in surgical excision with final pathology revealing phyllodes tumor.

RESUMO

Radiologic imaging techniques, such as F-18-fluorodeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT), provide diagnostic value in a variety of diseases. In cases of suspected infection, FDG PET/CT can find areas of fluorodeoxyglucose metabolism, correlating with local acute inflammation. The following case involves a man with end-stage renal disease (ESRD), who presented with symptoms of infection and positive blood cultures with high suspicion of arteriovenous fistula as the source of infection. The patient also had two central lines that could be a site of infection. Concerns for patient's persistent positive blood cultures necessitated FDG PET/CT to confirm site of infection. Confirming active infection and the source of infection guides therapeutic measures and eliminates concern for other disease etiologies common in patients with ESRD.
