“Dot in Circle” Sign in Actinomycotic Mycetoma on MRI and Ultrasound − A Case Series

Abstract

Mycetoma, a chronic granulomatous disease more common in tropical countries such as India, has been conventionally diagnosed by invasive and time-consuming modalities like biopsy and microbiological culture. This case series aims to stress on the benefits of leveraging magnetic resonance imaging and ultrasonography in the early diagnosis of mycetoma, avoiding the invasive techniques and preventing debilitating complications that may develop from delay in diagnosis.
