“…In ultrasound, a traumatic neuroma may appear as a homogenous circumscribed hypoechoic oval mass with no or even mild internal vascularity, however, it could appear as a mass with suspicious features including irregular shape, indistinct margins, and nonparallel orientation. [35][36][37][38] Al-Sharif et al reported the "tail sign" in ultrasound imaging of 50% of patients with traumatic neuroma which represents the fusiform growth of tissue along nerve fibers. 39 Due to the rare occurrence, the mammographic presentation has not been described accurately.…”

Breast conservative treatment (BCT) is currently accepted as the standard treatment option for breast cancer. Targeted ultrasound helps detect recurrent lesions, postoperative changes, and scarring tissue. In this pictorial essay, we review the ultrasound features of benign (seroma, hematoma, fat necrosis, traumatic neuroma, fibrosis/scarring) and malignant (recurrence, new primary cancer) causes of palpable lumps after BCT and provide images from our patients to illustrate some typical findings of common pathologies. Ultrasound, especially as an adjunct to mammography, can make a specific diagnosis in most cases.

Traumatic neuroma at the mastectomy site, unusual benign lesion, mimicking tumor recurrence: A report of two cases

Traumatic neuroma is not a true neoplasm but a reparative proliferation of axons, Schwann cells, and fibroblasts at the proximal end of transected or injured nerves resulting from trauma or surgery. Breast traumatic neuroma after breast surgery, with or without clinical symptoms, has rarely been reported. Once found, it should be differentiated from tumor recurrence, and tissue confirmation is necessary, although it is small in size and demonstrates a benign appearance in imaging studies. Herein, we present two cases of traumatic neuroma at the mastectomy site. They were incidentally encountered during ultrasound evaluation of mastectomy beds given concerns for potential recurrence or malignancy, and pathologic confirmation by ultrasound-guided core needle biopsy was sufficient for the diagnosis.

Rationale: Traumatic neuroma is a reparative proliferative response of the nerve after trauma or surgery, which rarely occurs in the breast. However, it must be distinguished from tumor recurrence. Patient concerns: A 78-year-old woman underwent left-sided modified radical mastectomy for invasive carcinoma, 7 years before this case. Two painless nodules near the mastectomy scar were discovered in regular follow-up physical examination. A 62-year-old woman had received right-sided modified radical mastectomy for intraductal carcinoma, 4 years before this case. An asymptomatic nodule near the mastectomy scar was detected during follow-up ultrasound (US) examination. Diagnosis: The lesions in both patients were diagnosed as traumatic neuroma. Interventions: The first patient underwent excisional biopsy. The second patient underwent US guided core-needle aspiration, followed by conservative therapy. Outcomes: Neither patient complained of any discomfort, nor both exhibited normal physical and US findings during follow-up examinations. Lessons: Newly discovered nodules with the benign imaging features near the mastectomy site of a patient, especially with the tail sign, traumatic neuromas should be taken into consideration. Routine US examination is important for follow-up of breast cancer patients who have undergone mastectomy.
