Recurrent neurotropic chloroma of the right ulnar nerve on (a) pretreatment Positron Emission Tomography (PET) outlined in red demonstrating resolution (b) of hypermetabolic activity after treatment to 24 Gy to (c) the field outlined in red. Biopsy proven recurrent neurotropic chloroma on high power view with Heamtoxylin-Eosin staining (d) along the right psoas muscle outlined in red on (e) pretreatment PET demonstrating resolution (f) of hypermetabolic activity after treatment to 24 Gy to (g) the field outlined in red.

Biopsy of the right psoas lesion was consistent with chloroma (Figure 1); CSF analysis and bone marrow biopsy were negative and polymorphism analysis did not detect any host cells. All sites demonstrated a clinical and radiographic response (Figure 1) on followup.
Recurrent neurotropic chloroma of the right femoral nerve outlined in red on (a) pretreatment Positron Emission Tomography (PET) and (b) coronal Computerized Tomography (CT) imaging with the (c) CT-based treatment field outlined in red.

MRI, computerized tomography (CT), and positron emission tomography (PET) were consistent with a right femoral nerve chloroma extending into the right inguinal canal (Figure 2).
