Giant anterior sacral meningocele presenting as bacterial meningitis in a previously healthy adult.

Meningocele may be asymptomatic and incidentally discovered. Presenting as a retrorectal mass, sacral meningocele may produce urinary, rectal, and menstrual pain. Anterior sacral meningocele may be the cause of tethered cord syndrome. This article presents a case of a previously healthy 39-year-old man with large meningeal herniation that occupied the entire pelvis who developed symptoms of bacterial meningitis. A 39-year-old man was admitted with fever, chills, headache and photophobia. Escherichia coli was isolated from cerebrospinal fluid culture. Moderate improvement regarding meningeal symptoms was noted due to intravenous antibiotic therapy, but intense pain in the lower back associated with constipation, fecal and urinary incontinence, and saddle anesthesia developed. Abdominal ultrasound was negative. Plain radiographs and computed tomography demonstrated sacral bone defect and retrorectal expansive mass. MRI confirmed anterior sacral meningocele with cord tethering. After posterior laminectomy and dural opening, communication between meningocele and intrathecal compartment was obliterated. Computed tomography-guided percutaneous drainage through the ischiorectal fossa was performed to treat residual presacral cyst. Delayed diagnosis in our patient was related to misleading signs of bacterial meningitis without symptoms of intrapelvic expansion until the second week of illness. In our patient, surgical treatment was unavoidable due to resistive meningitis, acute back pain, and symptoms of space-occupying pelvic lesion. Neurosurgical approach was successful in treatment of meningitis and neurological disorders. Computed tomography-guided evacuation of the residual retrorectal cyst was less invasive than laparotomy, resulting in normalization of defecation and miction despite incomplete evacuation. Further follow-up studies may provide insight into the most effective treatment of such conditions.

Ultrasonographically guided percutaneous dilatational tracheostomy after anterior cervical spine fixation.

Patients with anterior cervical spine fixation (ACSF) after acute spinal cord injury often require tracheostomy for prolonged ventilatory support and upper respiratory tract clearance. The authors report two patients with ACSF who underwent a successful ultrasonographically guided percutaneous tracheostomy with dilatation forceps technique. Possible advantages of the ultrasonographically guided method with dilatation forceps in patients with ACSF are discussed.

The role of interfascicular nerve grafting after gunshot wounds. A report of 44 cases.

In this study the authors present the results of 44 patients with 49 interfascicular nerve grafting procedures necessitated by gunshot wounds. The aim was to establish the effectiveness of microsurgical interfascicular nerve grafting for war injuries. The 49 interfascicular nerve grafting procedures were performed between July 1991 and January 1993. All but one were performed within 6 months of injury. Nerve recovery was assessed independently by a neurologist. The M/S scale was used for median, ulnar and radial nerves, and the grading scale recommended by Millesi was used for the sciatic, tibial and peroneal nerves. Follow-up was for between 2.5 and 3.5 years. Patients scoring at least M3/S3+, or Grade 2 on the Millesi scale, were considered to have useful functional recovery which occurred in high median (0 out of 1), low median (4 out of 9), high ulnar (0 out of 2), low ulnar (5 out of 11), high radial (4 out of 6), low radial (2 out of 2), sciatic (5 out of 9), peroneal (4 out of 7), and tibial (2 out of 2). The extent of recovery correlated inversely with the patient's age and the length of the graft, but was independent of the time between injury and surgery and of presumed projectile energy. Our results suggest that microsurgical interfascicular nerve grafting is of value in the management of wartime nerve injuries.

Anatomical variations of the median nerve in the carpal tunnel.

The median nerve was explored in 100 hands and the variations classified by the Lanz system. Only 47.7% of hands showed the standard anatomy described in textbooks. Rare variations were also found. Knowledge of the variable anatomy of the nerve could help to avoid incomplete decompression at operations for carpal tunnel entrapment and injury to the thenar branch of the nerve. The possibility of double thenar innervation must be considered in preoperative evaluation and in the follow up of median nerve injuries.
