9-year-old male with ALL on steroids, rule out AVN Right ankle: Confluent increased T2 and decreased T1 signal within the proximal aspect of the cuboid without discrete fracture line may represent a healing nondisplaced fracture or stress reaction. Multiple additional scattered foci of increased STIR signal within the marrow of the distal tibia, talus, calcaneus, and tarsal bones as well as the visualized portions of the metatarsals are normal for the patient's age. The tibiotalar joint is normal. The medial and lateral collateral ligaments are intact. The extensor and flexor tendons appear normal.Left ankle: Scattered foci of mildly increased STIR signal within the marrow are normal for the patient's age. There is no evidence of fracture or malalignment. The tibiotalar joint is normal. The medial and lateral collateral ligaments are intact. The extensor and flexor tendons appear normal.
Signal abnormality involving the right cuboid, which may represent a healing nondisplaced fracture or stress reaction. Right foot radiographs may be considered to evaluate for healing if clinical warranted.
