Isolated fallopian tube torsion (IFTT) is a rare form of adnexal torsion. A 2024 review described fewer than 150 cases over several decades. The clinical presentation of IFTT is highly variable and nonspecific, which may result in delayed diagnosis. Most patients present with acute unilateral abdominal pain with nausea and/or vomiting, while other patients may present with more gradual symptoms. Risk factors for IFTT include adnexal lesions, hydrosalpinx, previous pelvic surgery, and pelvic inflammatory disease. Ultrasound is particularly useful in identifying the imaging signs of IFTT, which include normal ovarian size and flow, a distended cylindrical structure that tapers to a “beak” adjacent to the ovary, thickened endosalpingeal folds resulting in a “cogwheel” appearance, and, lastly, a twisted vascular pedicle. We present an imaging-focused case in which the diagnosis of IFTT using ultrasound, following equivocal CT, resulted in prompt and confirmatory surgical management. Our goal is to raise awareness of IFTT as a possibility in females with abdominal pain and to discuss ultrasound characteristics that may increase clinical suspicion and diagnostic confidence. Prompt recognition and surgical management may prevent tubal necrosis and loss of fertility.

This cohort study examines trends in patient access of radiology imaging results after implementation of the 21st Century Cures Act in different clinical settings.

Risk factors include exogenous estrogen or androgen use, and genetic and metabolic syndromes. Management of HCA is delineated by sex assigned at birth; Observation is recommended in an HCA less than 5 cm in an individual assigned female at birth, while resection of an HCA in an individual assigned male at birth is recommended no matter the size due to risk of malignant transformation. What is not known is whether risk is different for individuals with gender incongruence on gender affirming hormone therapy (GAHT). There is limited data on the risk of HCA in this population. One case report of a transgender man who continued GAHT after diagnosis of an HCA though no follow-up information was available. We present follow-up on a transgender man assigned female at birth with multiple hemorrhagic HCA that was re-initiated on GAHT after stabilization of adenomas off GAHT. Unlike prior cases, the molecular profile showed ß-catenin negative, estrogen and androgen receptors positive. This is the first case report to our knowledge reporting detailed follow-up after restarting masculinizing GAHT after diagnosis of HCA. A 24-year-old transgender man presented to the emergency department with right upper quadrant pain. Initial labs were notable for ALT of 239 units per liter (U/L) and AST 165 U/L. Magnetic resonance imaging (MRI) of the abdomen and liver elastogram revealed multiple bilobar hepatic masses, the largest measuring 9.9 cm concerning for hemorrhagic HCA which was subsequently confirmed on liver biopsy. Immunostains were positive for estrogen and androgen receptors. The patient had no history of alcohol or illicit drug use, tattoos, or family history of liver disease. The patient had been treated with 100 mg of intramuscular testosterone cypionate weekly for the past six years for gender incongruence locally. No testosterone concentrations were available from prior to or during acute presentation. Discontinuation of hormone therapy was recommended along with conservative management with frequent MRI. Over the next 19 months, monitoring revealed improvement/resolution of the auto infarcting adenomas with the last MRI noting two stable HCA measuring 2.1 cm and 0.8 cm without new or enlarging liver lesions. Due to gender dysphoria off GAHT, reinitiation of hormone therapy with low dose AndroGel 1.62% topically was prescribed at 18 months after presentation. The patient has been monitored with labs monthly and plans to obtain MRI abdomen every three months. To date, the patient has tolerated reinitiation of therapy. This case demonstrates that patients on masculinizing GAHT who develop HCA can be conservatively managed and monitored based on pathology and that testosterone does not necessarily explain sex differences in the presentation/malignant transformation of HCA cisgender men as opposed to cisgender women.

ABSTRACT The management of hepatic adenoma in transgender individuals undergoing gender-affirming hormone therapy remains unclear, especially whether treatment should be based on sex assigned at birth or therapy patient received. We presented a transgender man, female at birth, with hepatic adenomatosis with molecular profile differed from typical adenomas in cisgender males on testosterone. Discontinuing testosterone led to autoinfarction of the adenoma, allowing the avoidance of invasive treatments and resumption of gender-affirming hormone therapy. This case underscores the necessity for personalized care in the growing transgender population and challenges current consensus of treatment based on sex assigned at birth, emphasizing a tailored approach.

ABSTRACT Mpox is a rare infection caused by the zoonotic orthopoxvirus. We present the case of a 44-year-old man with HIV and a history of kidney transplant who presented with mpox and developed proctitis-associated bowel obstruction, urinary retention, and eosinophilia. Our case highlights potential gastrointestinal manifestations of severe mpox infection.
