Imaging spectrum in tropical breast infections

Abstract

While breast carcinoma is the most feared pathology in women with breast lumps, infections continue to be an important aetiology, especially in countries with low to middle socio-economic status. The breast infections or mastitis can present as acute painful breast or recurrent episodes of breast lumps with or without pain. The common causes include puerperal, non-puerperal, and idiopathic mastitis whereas uncommon causes like tuberculosis, filariasis, hydatid and other parasitic infections are still seen in developing countries. Imaging with digital mammography may be difficult due to pain or inadequate due to increased breast density. Ultrasound serves as the modality of choice for detailed assessment in these patients. Since the imaging features are often overlapping with malignancy, biopsy is almost always indicated. However, there are certain imaging findings that may point to the diagnosis of mastitis and can help in accurate radiologic-pathologic correlation. This article aims to illustrate the varied clinico-radiological features of patients with tropical breast infections.
