Accessory muscle

Musculus

sternalis als anatomische Variante rechts neben dem Sternum vor dem M. pectoralis major. Computertomographie links axial und rechts in Volumen rendering - Rekonstruktion. Der Muskel kann gerade in axialen Bildern als Pathologie fehlinterpretiert werden.

Pseudotumoural

soft tissue lesions of the foot and ankle: a pictorial review. Accessory muscle. Sagittal T1-WI. An accessory soleus (black asterisk) is seen anterior-inferior to the soleus muscle (white asterisk), arising from the tibia (origin not shown) and with a tendinous insertion onto the superior surface of the calcaneus anteromedial to the Achilles tendon (arrow). This is just one of the five types of accessory soleus that have been described on the basis of insertion characteristics

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

Levator

claviculae muscle: a normal variant that may be misidentified as pathology.. Axial CT images in cranio-caudal direction show a left lipoma (arrowhead). The right levator claviculae muscle is seen (thin arrow) originating from the trapezius (thick arrow) and lying antero-laterally to the levator scapulae muscle (*).
