50-year-old man with a history of hepatitis C and cirrhosis Axial in-phase and out-of-phase 2D SPGR images (Figure 5.17.1) show a cirrhotic liver with moderate splenomegaly. The spleen contains multiple hypointense nodules that show signal loss on in-phase images relative to out-of-phase images. The low-signal-intensity lesions are also seen on axial fat-suppressed FSE T2-weighted image (...

We present a case of a solitary neurofibroma of the floor of the mouth protruding into the submandibular region. A 51-year-old female presented with a 2-year history of swelling of the floor of the mouth. MRI revealed that the mass measuring  mm showed a homogenous, low signal intensity on a T1-weighted image and high signal intensity on a T2-weighted image. The tumor was completely removed through a cervical approach. Cases of a solitary neurofibroma originating from the floor of the mouth are extremely rare.

Note also geographic decreased signal intensity in the left hepatic lobe, likely representing fibrotic changes from previous radiotherapy. Many of the lesions are more difficult to visualize on equilibrium phase images obtained 20 minutes after gadoxetate disodium (Eovist) administration (...
