case_images: MRI revealed an 8x27x29-mm contrast-free soft-tissue formation in the midpalmar space and another 6x8-mm lesion in the third and fourth metacarpal base region, which was contrast enhanced [Figure 1].

case_images: A 0.8x1.2-cm vascular mass was identified proximal to the third and fourth metacarpal base region just above the carpal tunnel causing compression to the tunnel [Figure 2].

case_images: An encapsulated mass was found to originate distal to the division of the nerve, spreading the fibers of the median nerve [Figure 3].

case_images: Histological examination revealed the midpalmar mass as a lipomatous tumor composed of mature adipocytes without intermingling nerve fibers and the vascular mass was diagnosed as an arteriovenous malformation [Figures 4 and 5].
