Ultrasound is a well-proven imaging modality for showing peripheral nerve disorders and guiding perineural injections. The aim of this review is to focus on small peripheral nerve abnormalities, which are usually not recognized by sonologists. In fact, most of these small nerves have a tiny diameter (<2 mm), and their anatomy is less familiar. We describe the most common causes of small peripheral nerve disorders, providing an accurate description of their anatomic locations and relationships with adjacent structures; we also focus on technical hints that may help in their evaluation.

Calcific tendinopathy (CTe) is a frequent disorder related to the deposition of calcium hydroxyapatite crystals within tendons. Ultrasound has been shown to be an excellent imaging modality for the evaluation of CTe. During the resorptive phase of CTe, calcium deposits may migrate inside the tendons or in neighboring tissues and lead to local inflammation and severe pain. In this pictorial essay, we describe the ultrasound appearance of a spectrum of CTe migrations. Knowledge of the different migration patterns can help sonologists in their detection and in establishing the correct diagnosis.

Calcific tendinopathy of the shoulder is a common condition caused by calcium hydroxyapatite crystals, affecting the tendons of the rotator cuff. Among uncommon complication, one is the migration of the calcium in the subacromion-subdeltoid bursa. More rare is the intraosseous migration. We present four cases of an even more rare condition, not well described in literature yet, the intramuscular migration of calcium.
