It measured approximately 3.0 x 3.0 x 3.5 cm in size on T1 postcontrast images  [Figure 1].
(a) In many areas, the tumor showed the classic appearance of intramuscular myxoma, characterized by a hypocellular tumor with prominent myxoid background, stellate - shaped cells and poorly developed vascularity. (b) In contrast, many foci of increased cellularity and vascularity (arrows) were identified. Note the lack of nuclear atypia, necrosis, and mitotic activity. (H and E, x20 objective)

Routine hematoxylin and eosin stains were performed on formalin-fixed, paraffin-embedded sections and showed a relatively well-circumscribed tumor composed of prominent myxoid stroma with a distinct presence of stellate-shaped bland cells with pyknotic nuclei and virtual absence of blood vessels [Figure 2a]. In approximately 20% of the tumor specimen, areas of increased cellularity and vascularity were noted [Figure 2b].

To date, 42 months after the surgery, the patient remains neurologically intact, feels well and no recurrence has been observed on sequential imaging [Figure 3a-f].
