Angiolipoma: a review of 778 lesions in 344 patients.

Background: Angiolipomas are benign subcutaneous nodules that are commonly multifocal and easily overlooked by those not familiar with their appearance. The objective of this study was to identify the spectrum of the clinical and imaging features of this lesion, to include MR, CT, and US features.

Methods: A retrospective review of our institutional pathology database for biopsy-proven cases of angiolipoma between January 1, 2019, through December 31, 2021, was done.

PET/CT Imaging of Hemorrhagic Pseudotumor Arising From Treated Plasmacytoma.

Hemorrhagic pseudotumor occurs in approximately 1% to 2% of patients with hemophilia. This lesion is exceptionally rare in nonhemophiliac individuals. The authors present a case of treated right ischial plasmacytoma with a progressively enlarging expansile hemorrhagic pseudotumor, documented on 18 F-FDG PET/CT and MRI and confirmed by histology.

Sonography of the Post-Operative Rotator Cuff: Normal Postoperative Findings, Postsurgical Complications and Common Artifacts.

This review sets forth an approach to performing and interpreting shoulder ultrasound in patients with prior rotator cuff repair and presents a comprehensive review of normal expected findings, postsurgical complications and common artifacts encountered in clinical practice.

Woven collagen biotextiles enable mechanically functional rotator cuff tendon regeneration during repair of segmental tendon defects in vivo.

Despite advancements in surgical techniques and materials for rotator cuff repair procedures, primary repair failures remain common. This study examines the use of electrochemically aligned collagen (ELAC) threads woven into biotextile scaffolds as grafts to repair critical infraspinatus tendon defects in New Zealand White rabbits. Three surgical treatment groups were evaluated: rabbits undergoing direct repair as operative controls, rabbits receiving ELAC scaffolds alone, and rabbits treated with mesenchymal stem cell (MSC)-seeded ELAC scaffolds.
