Erector Spinal Muscular Schwannoma of the Dorsal Ramus Nerve: A Case Report
نویسندگان
چکیده
We present a rare case of intramuscular schwannoma originating from the dorsal ramus nerve in a 62-year-old woman. The mass grew slowly, with pain developing upon touch five years prior. No neurological deficit was detected. The mass was observed in the erector spinae muscles in magnetic resonance imaging (MRI), and surgical excision was performed. The mass was well encapsulated with clear margin. The lesion appeared to originate from the cranial side. We completely removed the mass including the origin. Histopathology confirmed a schwannoma diagnosis. This is the first report, to our knowledge, of a dorsal ramus-nerve schwannoma within the erector spinae muscles.

متن کاملThoracic Nerve Root Schwannoma Filling the Spinal Canal Almost Entirely Without any Neurological Deficits
INTRODUCTION Spinal tumours may be classified in three groups: 1) extradural, 2) intradural extramedullary and 3) intramedullary spinal cord tumours. Intradural extramedullary tumours arise from the leptomeninges or nerve roots and include schwannomas. A schwannoma is usually a firm grey-whitish tumour growing near a nerve trunk or ramus. It can be separated from the nerve without damaging neur...

At about the 20-30 day of embryonic life "Somites" start to appear. In the middle of the fourth week the dorsal portion of each Somite differentiates into an epitheliallyarranged mass of cells called dermomyotome (from which the skin and muscles originate). The lateral part of the sermomyotome then proliferates to form dermatome (from ·which originates the derm and Hypoderm). The medial ...

Schwannoma is a rare benign neural neoplasm derived from Schwann cells of the peripheral nerve sheath. Schwannoma accounts for 25% to 48% of all neoplasm cases in the head and neck region. Oral Schwannoma is an uncommon soft tissue tumor comprising of 1% of all Schwannomas. Tongue is the most common location for oral schwannoma. Occurrence of gingival schwannoma is very rare and less than 10 ca...
