Third ventricular tumors vary in etiology. Treatment and surgical approach usually depends on preoperative diagnosis. Colloid cysts are the most common tumors of the third ventricle and the occurrence of two colloid cysts in the ventricular system is rare. ⋯ This is the third reported patient with dual or paired colloid cysts. It is the second report of a lateral and third ventricular cyst, and to our knowledge the first to be successfully managed with purely endoscopic techniques obviating the need for a craniotomy. This report illustrates the importance of a wide differential when investigating intraventricular lesions and provides another example of a purely endoscopic transcortical approach for the resection of colloid cyst.

Subarachnoid blood has been reported as a cause of chronic spinal arachnoiditis. Although syringomyelia has been thought to be caused by spinal arachnoiditis, reports of syringomyelia following aneurysmal subarachnoid hemorrhage (SAH) are very rare. We describe two patients with syringomyelia associated with chronic spinal arachnoiditis following SAH. ⋯ MRI revealed syringomyelia from the medulla oblongata to C6, and an enlargement of the lateral and fourth ventricles. After foramen magnum decompression and C1 laminectomy, a fourth ventricle-subarachnoid shunt was placed by insertion of a catheter. Spinal arachnoiditis and spinal syringomyelia are rare but important chronic complications after SAH.

Percutaneous vertebroplasty (PVP) has played an increasing role in the treatment of osteoporotic compression fracture. The number of prior vertebral fractures and prior vertebroplasties are important risk factors for future fractures. We prospectively evaluated the effectiveness of teriparatide therapy for 28 patients who had repeated and multiple new-onset vertebral compression fractures (VCF). ⋯ Teriparatide therapy significantly decreased visual analogue scale pain scores, increased Japanese Orthopaedic Association function scores, increased spinal bone mineral density, and prevented new-onset VCF. Teriparatide can be used in patients who have repeated and multiple new-onset painful VCF to avoid repeated vertebroplasty. Therapy should continue for at least six months to ensure it is effective.
