Necrotic intramuscular chloroma with infection: magnetic resonance imaging features.
We recently experienced the case of an intramuscular chloroma with infection in a 7-year-old boy diagnosed with acute myeloid leukemia. Conventional magnetic resonance imaging (MRI) showed that the lesion mimicked an abscess, but diffusion-weighted imaging showed no diffusion restriction. These results suggested that the interior cystic portion was serous. On histopathological findings, a chloroma was diagnosed on the wall of a mass. Culture of the interior fluid revealed that Klebsiella pneumoniae was present. MRI differentiation is difficult even with diffusion-weighted images.
