The chronic subdural haematomas in this patient may have been due to rupture of bridging veins caused by a very mild trauma not noticed by the patient and possibly aggravated by the anticoagulation therapy. Infratentorial chronic subdural haematoma should at least be a part of the differential diagnosis in elderly patients with cerebellar and vestibular symptomatology even without a history of trauma.
The Neurovent-P ICP measuring system is a safe and reliable tool for ICP monitoring. Handling of the Neurovent-P system is safe when performed properly.
We describe a subacute intracranial subdural haematoma following lumbar myelography. This rare but potentially life-threatening complication has been reported both after lumbar myelography and following lumbar puncture for spinal anaesthesia. We review 16 previously reported cases of intracranial haemorrhage following lumbar myelography, and discuss the pathogenesis. In all reported cases post-puncture headache was the leading symptom and should therefore be regarded as a warning sign.
3.0T TOF-MRA offers superior characterization of AVM angioarchitecture compared with 1.5T TOF-MRA. The image quality of MRA at both 3.0 and 1.5T is still far from equal to DSA, which remains the gold standard for characterization of AVM.
With the new diagnostic tools now available, microsurgical removal of spinal hemangioblastomas has a low morbidity rate, suggesting that surgical treatment should be considered even for asymptomatic sHBs in certain circumstances.
The results encourage further use of biodegradable materials for the described applications. Additional studies will be performed to investigate the usefulness of biodegradable devices in neurosurgery and to obtain long-term results.
This paper reports on a 55-year-old female who had undergone middle ear surgery 12 years previously and was admitted with a 6-months history of unilateral hearing loss and facial weakness. MRI and CT demonstrated a space-occupying lesion arising from the temporal bone and extending into the posterior fossa. Treatment consisted in complete tumour removal. Temporal and mastoid bone destruction associated with typical histological features led to the diagnosis of neoplasm of endolymphatic sac origin. Clinical, histological, radiological and intra-operative features of these rare tumours are described and discussed. The pertinent literature is reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
