Prolapsed Uterine Smooth Muscle Tumor of Uncertain Malignant Potential: A Case Report and Review of Radiologic Findings.

Introduction: Uterine smooth muscle tumor of uncertain malignant potential (STUMP) is a rare tumor that arises in the myometrium of the uterus. It is regarded as an intermediate malignant tumor according to the recent World Health Organization classification. Few studies have reported the radiologic findings of STUMP, and the differentiation of STUMP from leiomyoma remains controversial.

Huge Primary Clear Cell Hepatocellular Carcinoma: a Case Report and Review of Radiologic Findings.

Introduction: Clear cell hepatocellular carcinoma (HCC) is a rare subtype of HCC. Histologically, clear cell HCC is characterized by the cytoplasmic accumulation of glycogen with a clear cell appearance, constituting > 80% of tumor cells. Radiologically, clear cell HCC demonstrates early enhancement and washout similar to conventional HCC.

Value of threshold growth as a major diagnostic feature of hepatocellular carcinoma in LI-RADS.

Background & Aims: The Liver Reporting and Data System (LI-RADS) version 2018 simplified the definition of threshold growth to '≥50% size increase in a mass in ≤6 months'. However, the diagnostic value of threshold growth for hepatocellular carcinoma (HCC) remained unclear. We evaluated the value of threshold growth, as defined by LI-RADS v2018, in diagnosing HCCs.

Simplified LI-RADS for Hepatocellular Carcinoma Diagnosis at Gadoxetic Acid-enhanced MRI.

Background Although various modifications to the Liver Imaging Reporting and Data System (LI-RADS) at gadoxetic acid-enhanced MRI have been suggested, LI-RADS shows suboptimal sensitivity for hepatocellular carcinoma (HCC) and is perceived to be too complex. Purpose To evaluate clinical usefulness of a simplified LI-RADS for diagnosing HCCs of 30 mm or smaller at gadoxetic acid-enhanced MRI. Materials and Methods Patients who underwent gadoxetic acid-enhanced MRI examination and subsequent resection, transplantation, or biopsy for focal solid nodules of 30 mm or smaller between January 2019 and December 2020 at a single tertiary referral institution were retrospectively analyzed.

Uterine Angiolipoleiomyoma with US, CT, and MRI Findings: A Case Report.

Introduction: Angiolipoleiomyoma (ALLM) is a rare hamartomatous tumor of mesenchymal origin composed of smooth muscle, mature adipose tissue, and blood vessels in various proportions. Because of its histologic similarity to renal Angiomyolipoma (AML), it is also called uterine angiomyolipoma. Preoperative diagnosis of uterine ALLM is very challenging due to its uncommon incidence and absence of established characteristic imaging findings.

Gangliocytic Paraganglioma of the Gastrointestinal Tract: A Case Report of Cecal Origin.

Introduction: Gangliocytic paraganglioma is an extremely rare tumor that is composed of epithelioid, ganglion, and spindle cells. It has a predilection site in the duodenum, especially the periampullary region. The clinical course is usually benign, but a few cases of metastasis to lymph nodes or distant sites have been noted.

Embolization of Inferior Pancreaticoduodenal Artery Aneurysm with Celiac Stenosis or Occlusion: A Report of Three Cases and a Review of Literature.

True pancreaticoduodenal artery aneurysms are relatively rare, approximately 50% of which are associated with stenosis or occlusion of the celiac axis. It is imperative to treat the condition immediately after diagnosis, considering that its rupture has a mortality rate of approximately 50%. The current most commonly used method to treat pancreaticoduodenal artery aneurysms is transcatheter arterial embolization.
