Medial notch of the superior border of the scapula: a rare anatomical variation mimicking a bone tumour.

The scapula is a flat, triangular bone overlying the posterior chest wall and forming the posterior aspect of the shoulder girdle. To the best of our knowledge, there is no previous description of a notch of the medial aspect of the superior border of the scapula in the literature. The imaging findings of a supero-medial scapula border notch mimicking a bone tumour are presented in this case report.
