Solitary Bone Plasmacytoma: The Unusual Case with Involvement of Adjacent Disc Space

Background: Solitary plasmacytoma of the bone (SPB) is a rare manifestation of plasma cell tumor that usually presents as a osteolytic lesion mainly localized within the axial skeleton and the back pain is a common clinical feature.Case presentation: This case report discussed a 57-year-old male presented with low back pain caused by SBP. In this case, there is an even rarer phenomenon presented as osteolytic destruction in T7 to T9 vertebral bodies with involvement of adjacent disc spaces. This case report provided a comprehensive description of the radiographic assessment, medical management, and differential diagnosis.Conclusions: This is the first discussion focusing on differential diagnosis between spinal neoplasm and infectious diseases about SBP with involvement of adjacent disc space.

Spontaneous Healing of Brown-Sequard Syndrome Caused by Cervical Disc Herniation

Brown-Sequard syndrome (BSS) is most commonly seen in patients with spinal trauma and extramedullary spinal neoplasm. Pure BSS caused by cervical disc herniation is extremely rare. Operative treatment is generally recommended those patients with BSS to improve neurological function. Here, we report a rare case of spontaneous healing of BSS caused by cervical disc herniation. Two years follow-up showed complete disappearance of symptoms without recurrence. To our knowledge, no similar cases have been reported before. Therefore, for appropriate patients, conservative treatment can be considered for a few months before deciding on surgical treatment.

Percutaneous Endoscopic Removal of Cervical Foraminal Schwannoma via Interlaminar Approach: A Case Report

BACKGROUND AND IMPORTANCE Cervical foraminal schwannomas commonly originate from spinal nerves that pass through the intervertebral foramen of the cervical vertebrae. Because of the proximity of this type of tumor to the vertebral artery and spinal nerves, surgical management remains a major challenge. Conventional open spine surgery usually requires the removal of the articular process and is supplemented by a simultaneous posterolateral spine fusion surgery. To decrease the associated risks of surgical complications by further reducing invasiveness, percutaneous spinal endoscopy may be used for resection of foraminal spinal neoplasm. CLINICAL PRESENTATION A 52-yr-old female who presented with neck pains with duration of 1 yr was admitted to our hospital. Physical examination revealed moderate rigidity in the neck and grade 5 muscle strength in both upper and lower limbs. Preoperative magnetic resonance imaging (MRI) scans demonstrated a left-sided lesion at the C3-C4 intervertebral foraminal area. Under C-arm fluoroscopy navigation and neuromonitoring, the endoscope was properly positioned on the same side of the tumor, and a small part of the left C3 inferior and C4 superior lamina were first removed by an endoscopic drill to enlarge the interlaminar space. Next, through an endoscopic working canal, the left intervertebral ligamentum flavum was removed to fully expose the tumor. The tumor mass was finally resected in a piecemeal approach. Postoperative MRI confirmed complete tumor resection. CONCLUSION This is the first case report of a total removal of a cervical foraminal schwannoma with a percutaneous spinal endoscopic procedure.

Cervical disc herniation manifesting as a Brown-Sequard syndrome

ABSTRACTBrown-Sequard syndrome is commonly seen in the setting of spinal trauma or an extramedullary spinal neoplasm. The clinical picture reflects hemisection of the spinal cord. We report a rare case of Brown-Sequard syndrome caused by a large cervical herniated disc. A 63-year-old man presented with progressive right hemiparesis and disruption of pain and temperature sensation on the left side of the body. Magnetic resonance imaging showed large C3-C4 disc herniation compressing the spinal cord at that level, with severe canal stenosis from C4 through C7. Decompressive cervical laminoplasty was performed. After surgery, complete sensory function was restored and a marked improvement in motor power was obtained.
