Breast Imaging Spiculated Lesions

Mammographic screening for breast carcinoma has resulted in the detection of an increased number of nonpalpable lesions. One mammographic pattern suggestive of malignancy is the spiculated lesion, although it can also be produced by benign processes. Unfortunately, there are no radiographic criteria to reliably distinguish benign from malignant lesions. Hook wire-guided biopsy is of value in the management of the spiculated lesion and can permit the diagnosis of small or in situ breast cancers that have not yet spread to the axillary lymph nodes or beyond, thus improving the prognosis.
