Intracranial metastatic mucinous adenocarcinoma with characteristic features on diffusion-weighted imaging and in vivo magnetic resonance spectroscopy.
Intracranial abscesses and metastases are common lesions that might not be differentiated on routine MRI alone. In vivo proton spectroscopy and diffusion-weighted imaging have been used as complementary investigations for improved tissue characterization. In the present report we illustrate the role of mucin and its contribution to signal characteristics on diffusion-weighted imaging in a metastatic mucinous adenocarcinoma.
