Case in brief
A woman in her late 40s underwent bilateral skin-sparing mastectomy and immediate autologous breast reconstruction. During the procedure, bilateral sternalis muscles were unexpectedly identified. Preoperative imaging was retrospectively reviewed, confirming their presence. The recognition of these muscles facilitated safe exposure of the internal mammary vessels during reconstruction.
What made this case unusual
The discovery of bilateral sternalis muscles during breast surgery is noteworthy, as this anatomical variant is uncommon and often overlooked.
Diagnostic / clinical pearl
Clinicians should be aware of the sternalis muscle as an anatomical variant that may impact surgical planning and interpretation of imaging in breast surgery.
Why it matters
Understanding the presence of the sternalis muscle can enhance surgical orientation and prevent complications during breast reconstruction.
