We have reported three cases of iatrogenic lumbar meningocoeles after surgery for herniated lumbar intervertebral discs. We reject the term spurious, pseudo, or false as given by earlier writers. We feel that, in reality, these sacs are true meningocoeles, with complete arachnoidal lining and freely communicating with the intraspinal subarachnoid space. We have also given a brief outline of the...

Intracranial ependymal cysts are rare, congenital, benign lesions. These commonly occur in the supratentorial regions and usually generate no symptoms. The cerebellopontine angle (CPA) is an extremely rare site for ependymal cysts. Furthermore, there are no previous reports of CPA ependymal cysts related to syncope. We report a case of ependymal cyst in the left CPA with syncope. The patient un...

In three cases of subdural haematoma which resembled primary subarachnoid haemorrhage the diagnosis was made only by cerebral angiography. Angiography should be done whenever the diagnosis is in doubt.

Cerebrospinal fluid leaks pose a serious threat to patients as they represent an unchecked communication between the subarachnoid space and the extracranial environment. Accurate localization of the leakage site is essential for treatment planning. We describe the novel utilization of dual-energy computed tomography technology in cisternography in the evaluation of a patient with a cerebrospina...

To clarify the contribution of cerebral amyloid angiopathy (CAA) to subarachnoid haemorrhage (SAH) in the elderly, relationships between SAH and CAA were investigated in 997 necropsy cases aged 60 years or older. Primary SAH (bleeding from subarachnoid vessels) was found in 15 cases (1.5%). There was no case in which primary SAH was clearly attributed to CAA. Secondary SAH [secondary rupture of...

INTRODUCTION Vitreous or retinal hemorrhage occurring in association with subarachnoid hemorrhage is known as Terson's syndrome. In Terson's syndrome, intracranial hemorrhages are followed by intraocular hemorrhage, classically in the subhyaloid space, but may also include subretinal, retinal, preretinal, and vitreal collections. Vitreous hemorrhage recovery is usually spontaneous in six to 12 ...

Two groups of patients were allowed to self-administer morphine (n = 17) or pethidine (n = 15) extradurally after abdominal surgery, for a mean period of 16 h. Bolus increments of morphine 1 mg or pethidine 20 mg were administered by programmable pump. Pain relief from extradural patient-controlled analgesia (PCA) was excellent in all but two patients in the morphine group. Pain relief was not ...

Pain due to malignancy can be controlled through simple means in most patients. In certain refractory cases, however, the chronic delivery of analgesics to the epidural or subarachnoid space may be appropriate. This review will discuss criteria for patient selection for neuraxial drug delivery, the technologic systems available for neuraxial drug delivery, and criteria for selection of the appr...
