We present an interesting case of sacral perineural cyst which caused chronic perineal pain. Perineural cyst is relatively rare, especially the sacral region. Chronic perineural pain is an often encountered problem that is difficult to evaluate and sacral perineural cyst may be the etiology of chronic perineal pain in many instances.

A fetus with severe sacral agenesis and intrauterine growth retardation, ascertained at prenatal diagnosis, was found to be carrying an unbalanced form of a paternal balanced reciprocal translocation (7;19)(q36.1;q13.43), resulting in functional monosomy for 7q36.1-->qter. Necropsy confirmed that the fetus had isolated sacral agenesis type II. A critical region for autosomal dominant sacral age...

PURPOSE Conservative therapy and antimuscarinic agents are first line therapies for overactive bladder. Patients refractory to treatment are candidates for neuromodulation therapy. We estimated the costs and cost-effectiveness of percutaneous tibial nerve stimulation and sacral nerve stimulation. MATERIALS AND METHODS A Markov model was constructed to simulate the total costs and effectivenes...

PURPOSE To report results of sacral decompression and lumbopelvic fixation in neurologically impaired patients with highly displaced, comminuted sacral fracture-dislocations resulting in spino-pelvic dissociation. DESIGN Retrospective clinical study. SETTING Regional level one trauma center. PATIENTS Nineteen patients with highly displaced, comminuted, irreducible Roy-Camille type 2-4 sac...

Previously, a computer-based navigation system has not been used routinely for en-bloc resection of sacral tumors. In order to improve the accuracy of tumor resection, O-arm navigation was used to join anterior and posterior osteotomies during an en-bloc resection of a sacral Ewing's sarcoma. This case study describes the technique for en-bloc resection of a sacral Ewing's sarcoma guided by O-a...

Pr imary intraspinal pr imit ive neuroecto dermal tumors (PNETs) are rare. We report a case of sacral PNET with review the literature. A 15 -yearold boy presented w ith progres sive lumbar area pain, lower leg numbness and neurogenic bladder. Preoperat ive magnet ic resonance imag ing revealed a sacral tumor with epidural, presacral, and sacral bone extensions. An urgent operation was performed...

AIM Sacral stress fractures are rare fractures presenting themselves with low back and groin pain. These fractures can be treated effectively using sacroplasty. MATERIAL AND METHODS The clinical and radiological data of three cases that underwent sacroplasty for sacral stress fractures were reviewed. The pain severity was assessed using the VAS system. The radiological investigation was perfo...

Chordoma is a primary sacral neoplasm of ectodermal origin and makes up %1- 4 of all primary bone tumors. It is usually present on the midline cerebrospinal axis and the most common locations are the spheno-clival region and the sacrum. The treatment of primary sacral tumors represents a challenge because of a large tumor mass at presentation and a hemorrhage risk in surgery. Sacral tumors may ...

Neuromuscular stimulation via the sacral nerve roots is proposed for prevention of ischial pressure ulcers following a spinal cord injury (SCI). Acute effects of sacral functional magnetic stimulation (FMS) on seat interface pressure changes were investigated in five nondisabled volunteers. Similar effects were demonstrated with functional electrical stimulation in people with SCI who used a sa...

Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having...
