“…The ICBN is at risk during mastectomies, axillary lymphadenectomies, or any other surgical procedure that involves the axillary region, and severing this nerve has been found to cause postoperative numbness, significant paresthesia, and pain [ 4 ]. In general, axillary surgery in breast tumors can damage or lacerate this region's peripheral nerves.…”

“…As a result, patients have an increased risk of complications such as lymphedema, limited shoulder motion, and neuropathic pain [ 8 ]. The most common neuropathic complication of axillary dissection is intercostobrachial nerve syndrome due to an iatrogenic injury [ 4 ]. The present case describes an atypical anatomical variation of the ICBN found in a Puerto Rican elderly cadaver.…”

There are multiple treatment options for breast cancer (BC), including lumpectomy, chemo-and radiotherapy, complete mastectomy, and, when indicated, an axillary lymph node dissection. Such node dissections commonly lead the surgeon to encounter the intercostobrachial nerve (ICBN), which, if injured, leads to significant postoperative numbness of the upper arm. To assist in identifying the ICBN, we report a unilateral variation of a dual ICBN. The first ICBN (ICBN I) originates from the second intercostal space, as classically described in human anatomy. On the contrary, the second ICBN (ICBN II) originates from the second and third intercostal spaces. The anatomical knowledge of ICBN origin and its variations are crucial for axillary lymph node dissection in BC and other surgical interventions that involve the axillary region (e.g., regional nerve blocks). An iatrogenic injury of the ICBN has been associated with postoperative pain, paresthesia, and loss of upper extremity sensation in the dermatome supplied by this nerve. Therefore, maintaining the integrity of the ICBN is a worthy goal during axillary dissections in BC patients. Increasing the awareness of ICBN variants among surgeons reduces potential injuries, which would contribute to the BC patient's quality of life.
