1. Non-CNS lesions can occur anywhere, most commonly in the limbs and pelvis. Radiology plays a crucial role in detection, work-up, and management. 2. Complex tortuous anatomy must be delineated for proper management. 3. Ultrasound provides easy confirmation of suspected AVM and quantitative analysis. 4. Appropriate MR sequencing and proper CT and MR contrast timing vary based on location and size of AVM. 5. Angiography historically gold-standard for diagnosis, however currently reserved for management.

1. Initial presentation: patient characteristics; symptoms; dermatologic findings; syndromes- von Klippel- Trenaunay-Weber & Osler-Weber-Rendu. 2. Definition and classification: AVM vs. hemangioma vs. venous angioma vs. other vascular anomalies; Hamburg classification. Depicted with imaging and illustrations. 3. Diagnosis and Work-up: ultrasound including velocity waveform analysis and duplex doppler; MRA and CTA including sequencing, contrast timing, and 3-D reconstructions; Angiography; Radionucliotide-labeled microsphere shunt study; work-up algorithm. Depicted with imaging, video, 3-D reconstructions, and illustrations.
