A boy with growth disturbance caused by hypothalamic damage associated with intracranial hypotension syndrome following a motor vehicle accident: case report.
(42/87)
We examined the endocrine profile of a boy aged 10 years and 4 months with intracranial hypotension syndrome (IHS) following a motor vehicle accident. His complaint was growth disturbance. GH secretion gradually decreased and finally was lost in spite of an epidural blood patch procedure. His height velocity was restored by GH replacement therapy. MRI and SPECT revealed damage to the hypothalamic and pituitary gland. We concluded that growth disturbance is an important sign in pediatric patients with hypothalamic damage associated with IHS.

Rapid reduction of syrinx associated with traumatic intracranial hypotension by direct surgery: case report.
(45/87)
A woman in her early twenties presented with cerebellar tonsillar herniation with syrinx in the cervicothoracic spinal cord manifesting as postural headache after suffering trauma to the hip. She was treated under a diagnosis of traumatic intracranial hypotension. Cranial magnetic resonance (MR) imaging demonstrated tonsillar herniation to the upper rim of the C1 lamina, associated with effacement of the basal cisterns and flattening of the pons against the clivus, sagging of the optic chiasm, and protrusion of the pituitary gland into the suprasellar cistern. Spinal MR imaging and computed tomography (CT) myelography showed cervicothoracic syrinx and arachnoid diverticulum. Three applications of epidural blood patches produced no improvement. Surgery identified cerebrospinal fluid leakage from two small holes in the spinal dural sac, slightly proximal from the origin of the left L1 root sleeve, and arachnoid diverticulum. These two holes were sutured and a few sheets of gelatin sponge were placed around the arachnoid diverticulum and sealed with fibrin glue. The cervicothoracic syrinx was reduced significantly and tonsillar herniation disappeared within 10 days. Simple surgical repair of the dural tears may rapidly improve symptoms and imaging findings in patients with tonsillar herniation caused by traumatic intracranial hypotension. (+info)
Allogeneic epidural blood patch in the setting of persistent spinal headache and disseminated coccidioidomycosis.
(46/87)
In most cases of post-dural puncture headache, the positional symptoms will resolve spontaneously within 2 weeks. Conservative therapies include oral analgesics and hydration, bed rest, and abdominal binders. For refractory cases, an autologous epidural blood patch remains the treatment of choice. However, in certain cases the use of autologous blood for the blood patch may place the patient at risk for infectious or malignant contamination of the central nervous system. Coccidioidomycosis results from inhalation of the arthroconidia (spore) stage of the fungal lifecycle. The most common manifestation of coccidioidomycosis is acute pulmonary symptoms, while the most feared complication is meningitis. Immunocompromised patients are at increased risk of fungemia; therefore, introduction of fungal elements into the central nervous system can occur if autologous blood is used for an epidural blood patch. We report a case of persistent dural-puncture headache in the setting of disseminated coccidioidomycosis. An autologous blood epidural blood patch was considered but deferred due to risk of coccidioidomycosis meningitis. Other epidural space interventions such as fibrin glue injection or saline infusions were judged to be too imprecise or ineffective. The patient was successfully treated with allogeneic blood donated by his wife, but only after testing of her blood as is required for any directed blood donation. Allogeneic epidural blood patches are an option for refractory dural puncture headaches when autologous blood may cause meningitis or malignant seeding of the central nervous system. (+info)
Hemorrhage in regions remote from the site of initial intracranial operations is rare, but may be fatal. Postoperative cerebellar hemorrhage as a complication of supratentorial surgery, with a radiological appearance known as zebra sign, is an increasingly recognized clinical entity and is associated mainly with vascular neurosurgery or temporal lobe resection. The pathophysiology remains unclear. Three cases of remote cerebellar hematoma occurred after neck clipping of anterior communicating artery aneurysms. All patients had similar clinical findings and underwent pterional craniotomy with the head in accentuated extension. One patient died and the two were discharged without symptoms. Cerebellar hemorrhage probably has a multifactorial origin involving positioning associated with abundant cerebrospinal fluid drainage causing cerebellar sag with resultant vein stretching and bleeding, and use of aspirin or other antiplatelet agents.

Tension pneumocephalus as a complication of lumbar drainage for cerebral aneurysm surgery--case report.
(48/87)
A 66-year-old man developed tension pneumocephalus after failed lumbar drainage before clipping surgery for a ruptured anterior communicating artery aneurysm. After puncture with a Tuohy needle, the spinal catheter could not be inserted into the spinal dura, so surgery proceeded without the catheter placement. The patient's neurological status deteriorated suddenly into coma within 15 hours after uneventful clipping of the aneurysm. Computed tomography revealed tension pneumocephalus with marked brain shift. Intracranial hypotension was probably caused by continuous cerebrospinal fluid leakage from the iatrogenic spinal dural tear, resulting in air entry and accumulation into the cranium from an unidentified opening of the cranial dura. The patient was immediately treated with autologous epidural blood patch administration in the lumbar spine, followed by reopening of the craniotomy incision and flap to evacuate the accumulated air. The patient made a quick and uneventful neurological recovery after the rescue procedure. (+info)
