Four cases of echogenic breast lesions: a case series and review

Abstract

Echogenic breast lesions are generally thought to be benign. We herein report four cases of echogenic breast lesions that were seen at our centre over 38 months. One patient had a prior history of wide excision and radiotherapy for breast cancer and was imaged as part of routine cancer surveillance, while the other three were recalled for further assessment following an abnormal screening mammogram. All four patients were assessed on ultrasonography, which demonstrated an echogenic lesion in each patient. All four lesions underwent ultrasonography-guided core biopsy, followed by excision biopsy. The indications for biopsy were interval increase in the size of lesion or indeterminate features demonstrated in the lesion. Three lesions were benign, while the lesion from the patient who had received previous radiotherapy was angiosarcoma. Not all echogenic lesions are benign and lesions with suspicious features on ultrasonography should undergo biopsy.

Radiation‐induced myofibroblastoma within the nasal sinus requiring maxillectomy and ethmoidectomy: A case report and literature review

“…Radiation‐induced myofibroblastomas have been reported in the literature, most commonly concerning the breast. 14 , 15 An instance of radiation‐induced, low‐grade myofibroblastic sarcoma in the maxillary sinus was reported with a patient receiving radiotherapy for nasopharyngeal carcinoma, with the median radiation dose at the cancer site being 66 Gy during previous radiotherapy. 16 The reported latency in this case was approximately 60 years, which is a larger time duration when compared with reported solid tumor induction times 10 and for the case of reported myofibroblastic sarcoma in the maxillary sinus found in literature.…”
