Renal cell carcinoma presenting with upper gastrointestinal bleeding: A case report.

Renal cell carcinoma (RCC) is increasing in incidence as more cross sectional imaging is performed with approximately 20%-30% of cases presenting with metastasis at the time of diagnosis. Small bowel metastatic disease is rare, with RCC to the small bowel being exceptionally rare. We present a case report of metastatic RCC that initially presented as upper gastrointestinal bleeding at time of diagnosis. We also provide a brief discussion of small bowel metastatic RCC disease and literature review.

A case report: Retrograde arterial embolization of locally-injected SpaceOAR hydrogel material into the right common iliac artery bifurcation.

Biodegradable hydrogel-based matrices are becoming more widely utilized for a variety of medical applications, including SpaceOAR which is a hydrogel injected into the recto-prostatic space under ultrasound guidance to protect the rectum during prostate radiation therapy. Although a greater number of these procedures are being performed, there are no case reports on the potential complications which may result. In this report, we present the first case of retrograde embolization of SpaceOAR hydrogel into the right common iliac artery during routine office administration, as well as subsequent interventional angiography, inpatient and outpatient management, and clinical and imaging results at 1.5-month patient follow-up.

A rare case of metastatic uterine lymphoma in a renal transplant patient.

Primary and disseminated lymphoma of the female reproductive tract are rare types of lymphoma. However, in the setting of solid organ transplant, recipients have an approximately doubled risk of acquiring and dying from malignancy. Multiple treatment modalities are available for post-transplant lymphoproliferative diseases (PTLD), including chemotherapy, radiotherapy, surgery, and immunosuppression radiotherapy. We report a case of a 61-year-old female with multifocal nodal diffuse large B-cell lymphoma and a history of a renal transplant secondary to IgA nephropathy who developed metastatic diffuse large B-cell lymphoma to the uterus. While the baseline incidence of PTLD is elevated when compared with lymphoma in the general population, metastatic uterine lymphoma is rare. Awareness of reproductive organ involvement by lymphomas and increased malignancy risk in organ transplant patients are important considerations for diagnostic evaluation, including radiologic assessment.

Fatty-falciform ligament appendage torsion (F-FLAT): Diagnosis and management in a pediatric patient.

Fatty-falciform ligament appendage torsion (F-FLAT) is a rare condition manifested by torsion of the extraperiotoneal fat within the falciform ligament. It is similar to intraperitoneal focal fatty infarctions, including omental infarction and epiploic appendagitis. We report herein the first case of F-FLAT in a pediatric patient that failed conservative management. Ultrasound and CT scan facilitated prompt diagnosis of this rare finding and expedited a quick trial of conservative management. Despite conservative treatment, symptoms persisted for 4 weeks, but resolved after laparoscopic single-site surgical resection. In this report, we discuss the clinical features, key radiographic findings, and treatment options for this unique condition. This is only the third reported pediatric case of F-FLAT in the literature, and the first pediatric case to require surgical resection.
