T2 of the abductor digiti minimi and flexor digitorum brevis, diffuse muscular edema in short T1 inverse recovery (STIR), and heterogeneous enhancement of post gadolinium with no wall enhancement. There were no bony changes. This MRI reading together with the clinical picture was indicative of acute muscle infarction, indicative of myonecrosis (Figures 2-5).
Short T1 inverse recovery (STIR) showing enlargement of the muscle with diffuse heterogeneous increase in signal intensity, with no drop of signal on fat-saturated image and normal signal intensity of the bone.

T2 of the abductor digiti minimi and flexor digitorum brevis, diffuse muscular edema in short T1 inverse recovery (STIR), and heterogeneous enhancement of post gadolinium with no wall enhancement. There were no bony changes. This MRI reading together with the clinical picture was indicative of acute muscle infarction, indicative of myonecrosis (Figures 2-5).
Axial T2 showing abnormally high T2 signal intensity along the muscle fibers with involvement of the adjacent muscle (flexor digitorum brevis).

T2 of the abductor digiti minimi and flexor digitorum brevis, diffuse muscular edema in short T1 inverse recovery (STIR), and heterogeneous enhancement of post gadolinium with no wall enhancement. There were no bony changes. This MRI reading together with the clinical picture was indicative of acute muscle infarction, indicative of myonecrosis (Figures 2-5).
Axial T1 images post contrast demonstrating ill-defined heterogeneous enhancement of the abductor digiti minimi muscle, with no wall (ring) enhancement.

T2 of the abductor digiti minimi and flexor digitorum brevis, diffuse muscular edema in short T1 inverse recovery (STIR), and heterogeneous enhancement of post gadolinium with no wall enhancement. There were no bony changes. This MRI reading together with the clinical picture was indicative of acute muscle infarction, indicative of myonecrosis (Figures 2-5).
