Primary central nervous system lymphoma.

Primary central nervous system lymphoma (PCNSL) is a rare type of non-Hodgkin lymphoma (NHL) manifesting in the brain, spinal cord, cerebrospinal fluid and/or eyes, in the absence of systemic manifestations. With an increasing incidence and a 30% 5-year overall survival if promptly treated, timely diagnosis and subsequent treatment is paramount. The typical MRI appearance for PCNSL is a solitary or multiple T2-hypointense, homogeneous gadolinium-enhancing lesion with restricted diffusion.

A Comprehensive Grading System for a Magnetic Sentinel Lymph Node Biopsy Procedure in Head and Neck Cancer Patients.

A magnetic sentinel lymph node biopsy ((SLN)B) procedure has recently been shown feasible in oral cancer patients. However, a grading system is absent for proper identification and classification, and thus for clinical reporting. Based on data from eight complete magnetic SLNB procedures, we propose a provisional grading system.

A complete magnetic sentinel lymph node biopsy procedure in oral cancer patients: A pilot study.

Objectives: To assess the feasibility and merits of a complete magnetic approach for a sentinel lymph node biopsy (SLNB) procedure in oral cancer patients.

Materials And Methods: This study included ten oral cancer patients (stage cT1-T2N0M0) scheduled for elective neck dissection (END). Superparamagnetic iron oxide nanoparticles (SPIO) were administered peritumorally prior to surgery.

[A man with a dell over the symphysis pubica].

A 46-year-old man was referred to our emergency room after minimal trauma. He was diagnosed with symphysiolysis, which was based on a congenital variant instead of a traumatic injury.

What's new in MRI of peripheral nerve entrapment?

New developments in clinical peripheral nerve imaging with MRI over the past few years, primarily those related to nerve entrapment syndromes, are reviewed. The basic principles of peripheral nerve imaging are described briefly. Relevant current or forthcoming technical innovations are described, and then recent work describing novel findings, organized by anatomic location (brachial plexus, upper extremity, and lower extremity), is reviewed.
