Spontaneous intracranial hypotension (SIH) is a rare disease which is associated with variety of symptoms and signs including cranial neuropathies. Though diplopia occurred reportedly in about one fourth of SIH cases, trochlear nerve palsy has been reported only one case in the literature. A 71-year-old previously healthy male developed postural headache and nausea. After 15 days, he began to have diplopia caused by right trochlear nerve palsy. He consulted our hospital 2 months later because only diplopia was not recovered. Magnetic resonance imaging (MRI) showed bilateral thin chronic subdural hematoma (CSDH), brain sagging and downward brain stem displacement, but not ischemic change in brain stem. We suspected SIH for right trochlear nerve palsy, and he had symptomatic therapy. Two months later, he had burr hole surgery because of disturbance of consciousness and right hemiparesis due to progressive bilateral-CSDH. To say nothing of disturbance of consciousness and right hemiparesis, his trochlear nerve palsy was completely recovered after surgery at once. Follow-up MRI showed brain sagging and downward brain stem displacement were recovered.

The method of treatment for acute spontaneous subdural hematoma in aged patients is controversial. Three cases of acute spontaneous subdural hematoma in aged patients, treated by single burr hole drainage without irrigation, were reported. The first case, an 80-year-old male was admitted with complaints of headache and stupor without any history of head trauma. CT revealed a left subdural hematoma with mixed density. Intractable facial convulsion occurred three days after admission. Single burr hole drainage was performed to remove the hematoma, and facial convulsion disappeared one week after the surgery. The second case, a 70-year-old male was admitted with complaints of consciousness disturbance without any history of head trauma. CT showed a right subdural hematoma with mixed density. The next day, he recovered consciousness and CT demonstrated shrinkage of the hematoma. However, his consciousness deteriorated again 11 days after admission, and CT revealed progression of the hematoma. We performed single burr hole drainage, and the next day, his neurological condition recovered. The third case, an 84-year-old female was admitted with complaints of consciousness disturbance without any history of head trauma. CT revealed a left subdural hematoma with mixed density. Single burr hole drainage was performed to remove the hematoma. She recovered completely and was discharged and return home 1 month after the surgery. Single burr hole drainage is less invasive than craniotomy. Our three cases indicate that this method may be one of the best methods for aged patients with acute spontaneous subdural hematoma which manifests mixed density in CT.

We describe a case of spontaneous intracranial hypotension in a 36-year-old woman. This condition shares many of the features of post dural puncture headache, but without a dural puncture having been performed. The aetiology and management of this rare condition are discussed. We believe from experience within our own unit that most anaesthetists are unaware of spontaneous intracranial hypotension. Highlighting this condition is important, as anaesthetists are often involved in its management. In our case, radiological investigation involved the use of spiral computerised tomography to identify the site of the hole in the dura. Spiral computerised tomography is a relatively recent innovation, which may also be useful in the investigation of post dural puncture headache when the level of the puncture is unknown.

A 59-year-old male presented with a left organized subdural hematoma. The hematoma appeared as a homogeneous low density area on brain computed tomography and as hyperintense and isointense area on both fluid-attenuated inversion recovery and T2-weighted magnetic resonance (MR) imaging. Echo-planar diffusion-weighted MR imaging showed a crescent hyperintense area under the dura mater and an irregular hypointense area over the brain surface in the left subdural space. The apparent diffusion coefficient (ADC) values of the solid and liquid hematoma were 0.86 +/- 0.32 x 10(-3) and 2.56 +/- 0.39 x 10(-3) mm2/sec, respectively. The ADC value of the solid hematoma was similar to acute subdural or intraparenchymal hematoma, and that of the liquid was similar to cerebrospinal fluid. Burr-hole surgery failed to remove all the hematoma, and he complained of persistent headache. The hematoma was removed through a craniotomy without further neurological deficits. Organized subdural hematoma often requires craniotomy for evacuation because of its solid content. Diffusion-weighted MR imaging and measurement of ADC values can differentiate solid from liquid hematoma, so are useful for selection of the surgical procedure.

A 56-year-old man treated with anticoagulants complained of a gradually worsening headache. A left chronic subdural hematoma (CSH) was shown by head computed tomographic (CT) scans and the operation, one burr hole surgery under local anesthesia, itself was performed uneventfully. However, immediately after we began draining the hematoma at the patient's bedside, the patient complained of a sudden headache. CT scans showed a subarachnoid hemorrhage (SAH). Cerebral angiography was immediately performed, but the source of hemorrhage could not be found. The next day, a CT scan showed that most of the SAH had disappeared. To our knowledge, there are no previous reports of SAH of unknown origin following surgery for CSH. The likely mechanism for the occurrence of the SAH, in addition to a coagulopathy due to anticoagulant therapy, could include the possibility that the drainage of the hematoma produced a movement of the hemisphere along with hyperperfusion that resulted in the rupture of a weak subarachnoid vessel, such as a perforating artery.

We report a case of a 43-year-old man treated by craniotomy for chronical subdural hematoma (CSH) due to spontaneous intracranial hypovolemia. The patient complained of sudden onset severe headache. Initial CT scan showed normal brain structure, and his headache improved with bed rest in a few days. However, MR images obtained for vertigo one month later demonstrated bilateral subdural hygroma extending to the supracerebellar space and diffuse dural enhancement after gadolinium infusion. We diagnosed bilateral subdural hygroma due to spontaneous intracranial hypovolemia, and observed him conservatively. Four months after onset, he complained of severe headache again and MR images revealed enlargement of bilateral CSH with mass effect, which had heterogenous intensity on the right convexity. We evacuated hematoma on the right by craniotomy and aspirated the left side hematoma using a burr hole. His headache improved 2 weeks after the operation with strict bed rest. The follow-up MR images showed disappearance of abnormal meningeal enhancement and improvement of brain sagging.

Forty patients in whom the dura had been punctured accidentally and 10 patients who had received spinal anaesthesia required epidural blood patching for relief of severe postdural puncture headache (PDPH). Before injecting blood, the epidural pressure was measured, using an epidural catheter as a manometer. Mean epidural pressure in the left lateral position was 6.4 cm H(2)O (range 0.5-12 cm H(2)O). Epidural pressure was not related to the size of needle hole or prophylactic infusion of saline into the epidural space. In 5 patients with inadvertent dural tap, there was a statistically significant decrease (P<0.02) in epidural pressure from 14.9 cm H(2)O (range 11-22 cm H(2)O) before PDPH to 6.9 cm H(2)O (range 5-8.5 cm H(2)O) when they developed PDPH. The benefits of performing an epidural blood patch through a catheter placed in the epidural space are discussed.

Epidural anesthesia is the most versatile and widely used of the techniques for regional anesthesia. The most common complication of epidural or spinal anesthesia is postdural puncture headache. The loss of cerebrospinal fluid through the hole can be an important causative factor of this cephalalgia. Of the many methods recommended for preventing and treating postdural puncture headache, one is bolus administration or infusion of saline solution into the epidural space, by which both epidural and subarachnoid pressures are increased. We have reviewed the literature evaluating the effectiveness of this technique from 1967 to 2004, using the following search terms: anesthesia, spinal; anesthesia, epidural; analgesia, epidural; headache; postdural puncture treatment or prophylaxis; epidural injection; epidural saline. Few articles were found. The studies had small samples and most did not include a control group. The doses and methods of epidural administration of saline solutions were highly variable and the results were often contradictory. We conclude that using this technique to prevent and/or treat postdural puncture headache is difficult to justify.

More than 100 years have passed since the initial description of the postdural puncture headache (PDPH). However, this unique clinical entity still continues to fascinate anesthesiologists, and numerous studies on its pathophysiology, prevention, and treatment, have been published. There is considerable variability in the incidence of PDPH, which is affected by many factors such as age, gender, pregnancy, and needle type and size. The obstetric patient is at particular risk of dural puncture (and the subsequent headache) because of sex, young age, and the widespread application of regional anesthesia. The incidence of epidural needle-induced PDPH in parturients following dural puncture with a large bore needle has been reported to range 76-85%. Although a few measures have been proposed to prevent PDPH (intrathecal injection of saline, insertion of the epidural catheter into the subarachnoid space through the dural hole), none have been shown to work with certainty to date. This article reviews the latest developments (maintaining cerebrospinal fluid volume) aimed at prevention of PDPH.

Total removal of spheno-orbital fibrous dysplasia was achieved through intraoperative CT-assisted surgery via a burr hole. A 32-year-old man had persistent headache. Radiological studies demonstrated a small osteolytic lesion in the sphenoidal bone underneath the superior orbital fissure. Intraoperative serial CT scans showed the depth and width of the tumor within the complicated structure of the skull base. The lesion was successfully removed by CT-guided minimally invasive surgery.
