| description | The sternalis muscle, an uncommon anatomical variant of the chest wall musculature, though perhaps well known to anatomists, is quite
unfamiliar to clinicians and radiologists despite attempts to highlight its clinical importance in recent years. During routine dissection for
undergraduate medical teaching, in the department of anatomy, we came across two cases of sternalis muscle. The first was a unique
case of unilateral right sternalis with contralateral insertion on the left sternocleidomastoid, and the second case where bilateral presence
of the muscle was noted with ipsilateral insertion. The former was supplied by medial pectoral nerve and the latter by lower intercostal
nerves. Usually present between the pectoral and superficial fasciae, wide ranging prevalence and morphology have been attributed to
this muscular variant. Opinions differ on its development and nerve supply. Its presence can be misdiagnosed as a wide range of benign
and malignant anterior chest wall lesions and tumours, but it is also of great use as a pedicle flap or flap microvascular anastomosis in
reconstructive surgeries of anterior chest wall, head and neck and breast. In this paper, two cases of sternalis muscle which presented
very differently from each other are discussed. |
