Intraosseous schwannomas are benign tumours composed of nerve sheath cells, most commonly affecting the mandible and sacrum. Such intraosseous schwannomas in the vertebra can result in spinal instability causing deformity, pain and even neurological compression. Vertebral involvement in the lumbar spine is extremely rare. A case of a schwannoma of the lumbar spine at the level of L3/L4 is presented. It resulted in progressive lower back pain and right lower limb radiculopathy. The clinical findings, radiological reports and histological diagnosis of this case, along with a review of the literature, are presented. The rationale for non-surgical management of this rare benign tumour is also explored.

“…Dumbbell tumors can not only cause the compression of cervical cord and nerve root, but also invade the important structures and the surrounding organs, causing great harm to the patient [21] [22] [25] [26]. However, although useful in clinical practice, Toyama's classification system shows its low reliability and reproducibility in the study published by Mengchen et al (2017) [27].…”

Purpose: To report two quite rare cases of giant schwannomas of the cervical and thoracic spine. Surgical resection is usually the treatment of choice for these neoplasms. Methods: The first patient is a 48-year-old male that came to our department, complaining about weakness and paresthesia of both lower extremities and upper left extremity, and a considerably big dorsal palpable lump. MRI and CT scan were used to diagnose giant cervical schwannoma. Because of the intensity of symptoms, he was subjected to surgery. Multidisciplinary resection involving neurosurgical and oncosurgicalteamn was performed for intravertebral and extravertebral approaches. The second patient is a 55-year-old female that came to the hospital complaining about incapacitating pain and dysesthesia involving T6, T7, and T8 dermatomes, with no other deficits. MRI and CT scan were used to diagnose giant thoracic schwannoma. Because of the intensity of the pain, surgery was decided as the treatment of choice. Video assisted thoracoscopic surgery was performed and total resection was achieved, with improvement of the symptoms. Results: Both patients showed complete remission of the symptoms, with no major deficits after surgery. Conclusion: Although infrequent, giant spinal schwannomas may be the cause of visible lumps in the back with radicular symptoms. When asymptomatic, conservative treatment could be viable, but when they present symptoms, surgery offers good results.

“…Intramedullary schwannomas and intraosseous schwannoma (IOs) are quite rare tumors representing, respectively, less than 1% and less than 0,5% of all schwannomas. IOs usually present as osteolytic lesions that can mimic other aggressive tumors [3]. Relevant literature available about IOs is mostly represented by single case-reports of neoplasms [4].…”

Introduction: Schwannomas are the most frequent extramedullary intradural spinal tumors, accounting for approximately 24% of all nerve sheath tumors in adults. In a lower percentage of cases they may be extradural or transdural (1-19%). Intramedullary schwannomas and intraosseous schwannoma are quite rare tumors representing. Case Description: A 74-year-old woman presented intense low back pain for a few months, associated with left cruralgia and dysesthesia spread to both lower limbs. Magnetic resonance and computed tomography examination demonstrated an extramedullary intradural osteolytic lesion located in the posterior part of the vertebral body and pedicles of L1. The patient underwent a first surgery 4 years earlier with complete removal of the tumor but after about two years she had a recurrence. She was then subjected to a new intervention of decompression, removal of the tumor and arthrodesis. The histological findings were compatible with a classical schwannoma characterized by intraosseous growth and multifocal bone infiltration. Conclusion: We reported a rare case of intraosseous schwannoma presenting as a recurrence four years after radical surgical removal of a classic lumbar schwannoma. Only 25 cases of these tumors have been previously reported and none of them as an intraosseous recurrence.
