A. Axial FLAIR MR image through the brain shows a subcentimeter, hyperintense, superficial lesion in the left scalp. B. Axial T1-weighted, postcontrast image shows mild heterogeneous postcontrast enhancement. C. Axial diffusion-weighted image indicates restricted diffusion.

T2-hyperintense, mildly enhancing nodule with restricted diffusion in the left occipital scalp (Fig. 1). This was presumed also to represent a metastatic lesion.
A. Axial T2: Hyperintense, T2 infiltrative mass extends into the right gluteus maximus with solid and cystic components and an additional lesion situated within the right pectineus muscle. B. Axial T1 postcontrast: The right gluteus maximus lesion demonstrates rim enhancement around the cystic components and more solid enhancement in the medial aspect of the muscle. The lesion in the pectineus avidly enhances.

Imaging also demonstrated a metastatic implant in the right pectineus muscle (Fig. 2).
A. Coronal, T2-weighted, fat-saturated sequence demonstrates a hyperintense ovoid lesion in the anterior deltoid muscle. B. It is isointense to muscle on the axial T1-weighted sequence. C. Heterogeneous enhancement is demonstrated on the axial, T1-weighted, fat-suppressed, postcontrast image.

T2-hyperintense, avidly enhancing nodules, one in the anterior deltoid muscle and one in the medial head of the triceps (Figure 3, Figure 4). These lesions are presumed to represent further distant metastases, given the already proven metastatic disease.
A. The coronal T2-weighted sequence demonstrates a near-homogeneous, hyperintense lesion in the medial head of the triceps. B. The lesion is predominantly isointense to muscle on the axial T1-weighted sequence. C. It demonstrates heterogeneously avid enhancement on the axial, postcontrast, T1-weighted, fat-saturated image.
