Cervical Lymph Node Metastasis From Recurrent Glioblastoma Detected by MRI and 2-[18F]FDG PET/CT.

A 53-year-old man diagnosed with recurrent glioblastoma after multimodal treatment on a follow-up brain MRI. Because of a palpable mass in the neck, the patient underwent a whole-body 2-[18F]FDG PET/CT, which revealed hypermetabolic laterocervical confluent lymphadenopathies. A nodal cervical biopsy indicated distant metastases from glioblastoma.

Current role of imaging techniques in cardiac amyloidosis.

Cardiac amyloidosis (CA) is an underdiagnosed disease and, if left untreated, rapidly fatal. Emerging therapies for CA increase the urgency of developing non-invasive diagnostic methods for its early detection and for monitoring therapeutic response. Classic imaging features on echocardiography and cardiac magnetic resonance, although typical for cardiac amyloidosis, are not specific enough to distinguish light chain amyloidosis from transthyretin.
