Transcatheter arterial embolization for a symptomatic Tarlov cyst with hemorrhage due to an underlying arteriovenous fistula.

Symptomatic sacral perineural cysts (Tarlov cysts) accompanied by intra-cyst hemorrhage are rare. The treatment strategies have not been established. We report a 57-year-old woman with severe back pain due to a Tarlov cyst accompanying intracyst hemorrhage.

Timing of Uterine Artery Embolization for Leiomyoma during the Menstrual Cycle.

Purpose: To investigate differences in outcomes of uterine artery embolization (UAE) for leiomyoma when performed during different phases of the menstrual cycle.

Materials And Methods: In this single-institution retrospective analysis, 111 premenopausal patients (median [range] age, 44 [33-52] years) undergoing UAE for symptomatic leiomyoma between June 2014 and February 2020 were included. Twenty-one patients underwent UAE in the menstrual phase (the early follicular phase), 27 in the late follicular phase, and 63 in the luteal phase.

Ice Ball Cracks on CT During Cryoablation for Renal Tumors: A Retrospective Analysis.

Purpose: To evaluate the frequency of ice ball cracks on CT during cryoablation of renal tumors and assess the severity of hemorrhagic complications associated with this finding.

Materials And Methods: Between March 2014 and March 2019, 130 patients underwent CT-guided cryoablation using cryoprobes with a diameter of 1.5 mm for 138 renal tumors (mean diameter, 23.
