Medical imaging, including MR imaging [1], is playing an increasingly important role in the
diagnosis of disorders affecting the peripheral nerves and muscles [2, 3]. In the past, the …

Peripheral nerve tumors are not frequent, but due to their association with a nerve they are
somewhat special. They may be encountered incidentally during evaluation of a soft-tissue …

The natural history of intraneural perineurioma has been inadequately studied. The aim of
this study was to characterize the clinical presentation, electrophysiologic and imaging …

Patients with signs and symptoms of focal neuropathy are often referred for nerve imaging,
which may consist of regional magnetic resonance (MR) imaging of different areas of the …

Context.—Intraneural perineurioma may be confused with other “onion bulb” Schwann cell

Background Intraneural perineurioma is a rare peripheral nerve sheath tumor characterized
by localized proliferation of perineurial cells. The literature consists predominantly of case …

Peripheral nerve entrapments are frequent. They usually appear in anatomical tunnels such
as the carpal tunnel. Nerve compressions may be due to external pressure such as the …

The development of MR imaging has revolutionized soft tissue imaging. With its multiplanar
capability and ability to discriminate not only between different soft tissues but also …
