Preoperative Diagnosis of a Torsioned Accessory Spleen.

We report a case of a 12-year-old boy with an accessory spleen torsion. He presented with left-sided abdominal pain after trauma. A 4 cm oval mass without contrast enhancement was detected on contrast-enhanced computed tomography (CT), and ultrasound (US) showed a 4 cm oval mass below the spleen.

Diagnosing uterine cervical cancer on a single T2-weighted image: Comparison between deep learning versus radiologists.

Purpose: To compare deep learning with radiologists when diagnosing uterine cervical cancer on a single T2-weighted image.

Methods: This study included 418 patients (age range, 21-91 years; mean, 50.2 years) who underwent magnetic resonance imaging (MRI) between June 2013 and May 2020.

Carcinosarcoma of the ovary: MR and clinical findings compared with high-grade serous carcinoma.

Purpose: To clarify imaging and clinical characteristics of ovarian carcinosarcoma (CS) compared with high-grade serous carcinoma (HGSC).

Methods: We retrospectively reviewed MR imagings of 12 patients with CS and 30 patients with HGSC and evaluated tumor size, shape, appearance, nature of cystic and solid components, hemorrhage, and necrosis. Age, premenopausal or postmenopausal, histologic subtype, presence of endometriosis, tumor markers, and stage were also evaluated.

Location of major vessels in prone-positioned patients undergoing percutaneous lumbar sympathectomy.

Introduction: The topographic relationship between major vessels and the sympathectomy target is not identical across patients and may not be clear, especially in patients in the prone position. The aim of this study was to provide anatomic data regarding the location of the major vessels (i.e.
