چکیده
Diagnosis of intraneural conditions can be revealed by a combination of clinical examination, electrophysiology, magnetic resonance imaging (MRI), and targeted fascicular biopsy with subsequent microscopic analyses.

Nerve ultrasound and 3D-MR neurography suggestive of intraneural perineurioma.
An 8-year-old girl presented with progressive painless right peroneal and tibial nerve palsy. A 20-year-old woman had insidious weakness of the left wrist and fingers extension. Both underwent neurophysiology (tables e-1 through e-4 on the Neurology® Web site at Neurology.org) and nerve ultrasound that showed enlargement of sciatic (figure, A) and radial nerve (figure, D–E). A 3D–magnetic reson...
متن کاملIntraneural perineurioma affecting multiple nerves: a case report and literature review.
Intraneural perineurioma is a neoplasm of perineurial cells, corresponding to WHO grade I. We present a case of intraneural perineurioma affecting multiple nerves, which usually involved one or two of major nerve trunks in one patient. We describe the clinical presentation, magnetic resonance (MR) neurography characteristics, and pathological characteristics. The differential diagnosis with oth...
متن کاملMRI of intraneural perineurioma of the brachial plexus
Intraneural perineurioma is an uncommon benign tumor of the perineurium of peripheral nerve sheaths occurring primarily in adolescents or young adults. MRI is a valuable tool in suggesting this diagnosis and in surgical planning. We report an 18-year old female with progressive right-hand weakness, numbness, and severe atrophic changes of the hand secondary to an intraneural perineurioma involv...
متن کاملIntraneural reticular perineurioma of the hypoglossal nerve.
BACKGROUND Intraneural perineurioma or reticular perineurioma, which is 1 variant of extraneural perineurioma, has been rarely reported in the head and neck region. METHODS We report a case of a 52-year-old woman who wasseen with a swelling in the neck. A mass was found located on the medial aspect of the left submandibular gland and was palpated with a sponge-like texture. The mass was seen ...
متن کاملIntraneural malignant perineurioma: a case report and review of literature.
The great majority of malignant peripheral nerve sheath tumors (MPNSTs) exhibit Schwann differentiation. Few MPNSTs with perineurial differentiation are also named malignant perineuriomas. Benign perineurioms were classified as intraneural, extraneural (soft tissue), sclerosing, and reticular variant. Histopathological features of intraneural perineurioma are individual nerve axons surrounded b...
