RESUMEN
Venous malformations and hemangiomas of the skeletal muscle are separate entities with different clinical presentation, histology, and imaging findings. Recent advances in the field of vascular anomalies and current efforts in the unification of terminology by the International Society for the Study of Vascular Anomalies are pivotal in understanding and differentiating intramuscular venous malformations and intramuscular capillary-type hemangioma. Fibroadipose vascular anomaly is another recently defined vascular anomaly affecting the skeletal muscle, with a distinct clinical presentation, histology, and imaging appearance. These 3 distinct vascular anomalies are reviewed and their histologic features, clinical presentation, imaging appearance, and treatment are discussed.

Background: Median arcuate ligament (MAL) syndrome is a rare cause of chronic abdominal pain in adults and children. Release of the MAL has traditionally been performed open or laparoscopically. There have not been any published cases to our knowledge of robotic-assisted MAL release in pediatric patients. Patients and Methods: Two adolescent patients, aged 12 and 15 years, at our institution underwent robotic-assisted MAL release. The procedure involved dissecting the MAL muscle fibers and overlying scar tissue. Patients stayed inpatient postoperatively overnight and with an average outpatient follow-up of 10 months. Results: Both patients had immediate pain relief postoperatively and at 10-month follow-up had no recurrent symptoms. No complications were associated with the procedure. Conclusion: The increasing role of robotic surgery as a new surgical technique is gaining momentum for many procedures. This new approach for MAL release in the pediatric population was explored by our institution. It was found to be successful, safe, and reproducible for future patients.

Discoid meniscus (DM) is currently considered as a spectrum of disorders in meniscal shape and stability. Diagnosing DM on MR imaging has clinical and surgical implications. When diagnosing a DM on MR imaging, identification of tears and signs of instability is of utmost importance. The literature has focused on the diagnosis of DM based on morphology as complete, incomplete, and Wrisberg type, the latter lacking posterior attachments. This article reviews the relevant anatomy, histology, and clinical presentation of DM in the pediatric population.
