retrotrochleare Eminenz

Pseudotumoural
soft tissue lesions of the foot and ankle: a pictorial review. Accessory muscle: peroneus quartus. Axial T1-WI at the level of the subtalar joint (a) and slightly below (b). Peroneus quartus (long arrow) positioned posteromedial to tendons of the long (short arrow) and short (arrowhead) peroneal muscle. Several types of peroneus quartus are described based on the distal insertion, which can be onto the peroneal tubercle or the retrotrochlear eminence of the calcaneus, and less frequently the cuboid, the peroneus longus or the inferior peroneal retinaculum

The retrotrochlear eminence is located posterior to the peroneal tubercle and the peroneal tendons.

It is one of two bony projections or protuberances that may be seen arising from the lateral wall of the calcaneum, the other being the peroneal tubercle.

It is seen to be prominent in individuals with a hypertrophied peroneus quartus muscle, the most frequently reported accessory peroneal muscle. The muscle arises from the inferolateral aspect of the fibula and has variable insertions, one of them being the retrotrochlear eminence.
