TI inversion recovery hyperintense signal was noted in the head and body of the metatarsal associated with significant surrounding myofascial edema [Figure 1]. The MRI findings hinted toward an infective etiology rather than of traumatic antecedence.

On extending the incision, two long, coiled, ivory-colored, nonmotile parasites were discovered [Figure 2].

Institute (IVRI), Izatnagar, Uttar Pradesh, for further examination and final identification. It was communicated by the IVRI that the specimen forwarded was in all probability sparganum of spirometra because no cuticle was seen in any of the histological sections examined, but the outer wall greatly resembled with tegument of the plerocercoid larva [Figure 5]. It was also reported that although the anterior end was damaged, the morphological details and histology of the specimen submitted confirmed and compared well to the probability of sparganum of Spirometra spp.
