Background: Percutaneous biopsy under computed tomography (CT) guidance is a standard technique to obtain a definitive diagnosis when spinal tumors, metastases or infections are suspected. However, specimens obtained using a needle are sometimes inadequate for correct diagnosis. This report describes a unique biopsy technique which is C-arm free O-arm navigated using microforceps. This has not been previously described as a biopsy procedure. Case description: A 74-year-old man with T1 vertebra pathology was referred to our hospital with muscle weakness of the right hand, clumsiness and cervicothoracic pain. CT-guided biopsy was performed, but histopathological diagnosis could not be obtained due to insufficient tissue. The patient then underwent biopsy under O-arm navigation, so we could obtain sufficient tissue and small cell carcinoma was diagnosed on histopathological examination. A patient later received chemotherapy and radiation. Conclusions: C-arm free O-arm navigated biopsy is an effective technique for obtaining sufficient material from spine pathologies. Tissue from an exact pathological site can be obtained with 3-D images. This new O-arm navigation biopsy may provide an alternative to repeat CT-guided or open biopsy.

Intraosseous Meningioma

Primary intraosseous meningiomas (PIMs) are rare tumors that present with a variable radiological appearance and a clinical behavior that is considerably different from that of intracranial meningiomas. Treatment of PIMs consists of complete resection, which may be difficult to achieve due to the lack of clear tumor margins on conventional imaging studies. PET/CT using 68Ga-DOTA–conjugated peptides has been used for the diagnosis and treatment planning of different types of meningiomas due to these tracers’ affinity to somatostatin receptors, which are found in most meningiomas. However, this imaging modality’s use as an intraoperative adjunct has not been reported for PIMs. In this technical note, the authors describe a [68Ga-DOTA0-Tyr3]octreotide (68Ga-DOTATOC)-PET/CT–guided resection of a PIM. In this case, the area of increased uptake in the 68Ga-DOTATOC-PET/CT study extended well beyond the tumor margins identified on MRI. The patient’s pathology report confirmed the presence of tumor cells within peripheral bone, which macroscopically appeared normal. The authors propose 68Ga-DOTATOC-PET/CT as a valuable adjunct in the surgical management of PIMs and offer a reasonable justification for its use based on current evidence. Its use for intraoperative image guidance may aid neurosurgeons in achieving a complete resection, thus minimizing the risk of recurrence of this complex pathological entity.

Wrong Site

Intraoperative localization in spinal surgery is essential to facilitate the best surgical outcome and to avoid wrong-site surgery. Intraoperative fluoroscopy is generally adequate, but anatomical variation, body habitus, and the inherent difficulties of fluoroscopy at certain levels may lead the surgeon astray. Here, the authors present their technique for preoperative localization that relies solely on fixed anatomical landmarks using CT-guided, percutaneously placed radiopaque markers. In the outpatient setting, low-dose CT scanning of the neuraxis is performed to identify fixed landmarks and, under local anesthesia and CT guidance, a pushable microcoil is inserted through a Chiba needle into the periosteum of the pedicle at the level of interest. The patient returns home with no precautions while the coil is in situ, and then the patient returns sometime later for surgery. Intraoperatively, typically a single lateral radiograph is required to visualize the coil and the level. Preoperative placement of radiopaque markers at the level of interest is an effective tool for avoiding wrong-site surgery, especially in circumstances in which fluoroscopy may be troublesome. The authors’ method is accurate, effective, and expeditious and can be performed easily in the outpatient setting.

Lower Lumbar

Upper lumbar (L1–2, L2–3) disc herniations are distinct in their diffuse presenting clinical symptomatology and have poorer outcomes with surgical intervention than those following mid and lower lumbar disc herniations and disc surgery. The authors present the cases of 3 patients with L1–2 disc herniations and significant stenosis of the spinal canal. The surgical approach used here combined the principles of transforaminal percutaneous endoscopic discectomy and the extreme lateral lumbar interbody fusion procedures with intraoperative CT-guided navigational assistance. The approach provides a safe corridor of direct visualization to the ventral thecal sac with minimal bony resection and could, in principle, reduce neurological injury and biomechanical instability, which likely contribute to poor outcomes at this level.
