Splenic artery steal syndrome after liver transplantation: A case series and review of literature.

Splenic steal syndrome (SASS) represents a challenge to interventional radiologists after orthotopic liver transplantation. In this case series, we present three cases of patients who developed SASS after their liver transplants.

Budd-Chiari syndrome treated with direct intrahepatic portocaval shunt: A case report.

Budd-Chiari syndrome is an uncommon disorder characterized by occlusion of hepatic veins. It can lead to portal hypertension. Most common causes of this syndrome are hypercoagulability states. Transjugular intrahepatic portosystemic shunt is often not possible given the portal venous thrombosis. In these cases, direct intrahepatic portocaval shunt, involving the creation of an access between the portal vein and the systemic circulation via the intrahepatic inferior vena cava has proven to be a feasible alternative, and can improve portal hypertension in these patients. Herein, we present a case of a 37-year-old woman diagnosed with Budd-Chiari syndrome that was successfully treated with percutaneous ultrasound (US)-guided direct intrahepatic portocaval shunt.

Review of Breast Imaging in Transgender and Gender-Diverse Patients: Gender-Affirming Care, Histopathologic Findings, Breast Cancer Risk, and Screening Recommendations.

Gender diversity, especially pertaining to transgender and gender-diverse (TGD) populations, is often stigmatized. A small but not insignificant number of adults in the United States identify as TGD, including transgender, nonbinary, and other gender identities than cisgender. Accessing health care remains a significant challenge for TGD individuals because many health care systems adhere to a gender binary model and many TGD individuals experience negative interactions when interfacing with health care. There is also a scarcity of literature addressing their unique health care needs, limiting our current understanding of breast cancer risks and screening recommendations for TGD patients. This article reviews important considerations when providing care to TGD patients. It covers background information on gender identity and sexuality, explores gender-affirming care, discusses histopathologic findings of breast biopsy specimens, examines breast cancer risks, and presents current breast cancer screening recommendations for TGD patients. Education on TGD breast cancer risks and screening and creating a standardized screening protocol for TGD patients who may receive gender-affirming care through hormonal and surgical therapies could help improve their health care equity and access.

Clinical diagnostic and radiographic features of recurrent intracranial malignant triton tumor in an adult: illustrative case.

BACKGROUND: Malignant triton tumors (MTTs) are a rare and aggressive type of malignant peripheral nerve sheath tumor identified histologically by focal rhabdomyoblastic differentiation. OBSERVATIONS: A 37-year-old female with a prior history of Hodgkin lymphoma presented with acute-onset confusion, cognitive deficits, and weakness. Brain magnetic resonance imaging revealed a hemorrhagic intracranial mass later confirmed to be a malignant triton tumor. The patient underwent two resections and several courses of chemoradiation for multiple tumor recurrences and metastases. Unfortunately, despite extensive treatment, she died 2 years after initial presentation from complications of this tumor. Her overall survival (OS) of 26.7 months was double that reported in historical cohorts (OS ∼13 mos). LESSONS: The diagnosis and treatment of central nervous system MTTs are difficult and require a multidisciplinary team of neurosurgeons, radiologists, and oncologists. Histopathological analysis is required for confirmation of diagnosis. Gross-total resection of tumor and adjuvant radiation therapy have been shown to give patients the highest rates of survival and improved outcomes. Further studies and clinical trials are warranted to investigate the efficacy of chemotherapeutic agents like temozolomide, bevacizumab, and abemaciclib.

Meckel's diverticulum: Unusual cause of significant bleeding in an adult male.

Meckel's diverticulum is a common congenital gastrointestinal malformation affecting 2% of the general population. Most affected patients are asymptomatic, and excessive bleeding causing a significant drop in hemoglobin count is an uncommon complication of Meckel's diverticulum, especially in adult patients. Herein, we present an adult case of Meckel's diverticulum that nearly led to hemodynamic instability. Laparotomy and segmental small bowel resection were critical in treating the patient.

PET/CT Imaging in Treatment Planning and Surveillance of Sinonasal Neoplasms.

Sinonasal cancers are uncommon malignancies with a generally unfavorable prognosis, often presenting at an advanced stage. Their high rate of recurrence supports close imaging surveillance and the utilization of functional imaging techniques. Whole-body 18F-FDG PET/CT has very high sensitivity for the diagnosis of sinonasal malignancies and can also be used as a "metabolic biopsy" in the characterization of some of the more common subgroups of these tumors, though due to overlap in uptake, histological confirmation is still needed. For certain tumor types, radiotracers, such as 11C-choline, and radiolabeled somatostatin analogs, including 68Ga-DOTATATE/DOTATOC, have proven useful in treatment planning and surveillance. Although serial scans for posttreatment surveillance allow the detection of subclinical lesions, the optimal schedule and efficacy in terms of survival are yet to be determined. Pitfalls of 18F-FDG, such as post-surgical and post-radiotherapy crusting and inflammation, may cause false-positive hypermetabolism in the absence of relapse.
