    CSF drainage in patients with posterior fossa tumours (1992)

    Notes: Summary The management of hydrocephalus secondary to a posterior fossa tumour is controversial. We audited recent practice with a retrospective analysis of 287 consecutive patients undergoing posterior fossa exploration for tumour. 85 shunts and 112 external ventricular drains (EVD) were placed. The overall CNS infection rate in the series was 6%. There was a significantly higher (p 〈 0.01) infection rate in patients who had a drainage procedure, and a trend towards higher infection rates in patients with two drainage procedures. Early infection rates with EVDs and shunts were the same (7%). One third of patients with hydrocephalus had pre-operative drainage, a third had per-operative drainage but only a quarter required a permanent shunt. The majority of patients will not require a permanent shunt and where temporary CSF diversion is required EVD is reasonable.

    “Dural tail” adjacent to a giant posterior cerebral artery aneurysm: case report and review of the literature (1997)
    Springer

    Notes: Abstract The “dural tail” sign on gadolinium (Gd-DTPA)-enhanced MRI has been described in association with meningiomas. Various series with histopathological correlation have shown that in some cases there is tumour invasion into the dura mater, but in the majority of cases it represents a hypervascular, non-neoplastic reaction. While this sign was originally thought to be specific for meningioma, subsequent case reports have described the presence of a dural tail in other intra- and extra-axial lesions. We present a patient with a giant aneurysm arising from the P2 segment of the right posterior cerebral artery, adjacent to the tentorium, with a prominent dural tail on Gd-DTPA-enhanced MRI. In this location, differentiation of an aneurysm from a meningioma was critical.

    MRI in children receiving total parenteral nutrition (1996)
    Springer
    Neuroradiology 38 (1996), S. 680-683 
    Details
    ISSN: 1432-1920
    Keywords: Key words Parenteral nutrition ; Manganese ; Basal ganglia ; Magnetic resonance imaging

    Topics: Medicine
    Notes: Abstract Cranial MRI was obtained in 13 of a group of 57 children receiving long-term parenteral nutrition, who were being investigated for hypermanganasaemia. Increased signal intensity on T1-weighted images has been reported in adult patients on long-term parenteral nutrition and with encephalopathy following chronic manganese exposure in arc welding. It has been postulated that these changes are due to deposition of the paramagnetic trace element manganese. In excess manganese is hepato- and neurotoxic and we present the correlation of whole blood manganese levels with imaging findings. The age range of our patients was 6 months to 10 years, and the duration of therapy 3 months to 10 years. In 7 children we found characteristic increased signal intensity on T1-weighted images, with no abnormality on T2-weighted images. All patients had elevated whole blood manganese levels, suggesting that the basis for this abnormality is indeed deposition of manganese within the tissues.

    Intraosseous vertebral haemangioblastoma: MRI (1996)

    Notes: Abstract A 30-year-old man with low back pain and gradual onset of cord compression was found to have a highly vascular extradural tumour in the lower thoracic region. Involvement of the right pedicle and a large part of the body of T9 suggested a vertebral haemangioma, but histology revealed haemangioblastoma. One case of an intraosseous haemangioblastoma has been described previously; we present the features of another case shown by MRI and discuss the differentiation between haemangioma and haemangioblastoma.
