Case Reports
Intramedullary spinal cord metastasis of renal cell carcinoma 6 years following the nephrectomy.
Intramedullary spinal cord metastasis is an uncommon manifestation of systemic tumor. We present a case of metastatic mass inside the thoracic spinal cord 6 years after nephrectomy because of renal cell carcinoma. ⋯ The case shows that renal cell carcinoma has the possibility of metastasis into spinal cord even several years after nephrectomy. Any symptom of neurological deficit should alert to a possible intramedullary spinal cord metastasis.

Piriformis syndrome is a rare neuromuscular disorder that occurs when the piriformis muscle compresses or irritates the sciatic nerve. The treatment of piriformis syndrome includes injections into the piriformis muscle around the sciatic nerve. These invasive approaches have been used with various techniques to increase the safety of the procedure. Computed tomography (CT)-guided injection of the piriformis muscle and the clinical outcome of the patients are discussed. ⋯ CT-guided piriformis injection is a safe and effective method in the treatment of piriformis syndrome.

To evaluate the feasibility of this novel surgical approach for treatment of cervical discitis and vertebral osteomyelitis. ⋯ The described technique using AI-PMMA offers immediate structural stability and local delivery of high concentration of antibiotics. Use in two patients has demonstrated a cost effective, long-term biomechanically stable construct and infection control.

To demonstrate the incidence of screw misplacement and revision rates in a group of 72 patients that underwent pedicle screw fixation for spinal pathologies using the conventional, fluoroscopy-guided open technique. ⋯ Conventional open technique in pedicle screw placement is a safe and sound method with its low and acceptable complication rates.

We set out to investigate the optimal timing for shunt placement in patients with hydrocephalus after decompressive craniectomy (DC). ⋯ Cranioplasty and ventriculostomy followed by a second stage placement of a ventriculoperitoneal shunt are associated with fewer complications in the treatment of hydrocephalus after DC.
