    Anomalous portal venous connection to the suprahepatic vena cava: sonographic demonstration (1989)
    Springer
    Pediatric radiology 20 (1989), S. 115-117

    Notes: Abstract The authors report a congenital portosystemic shunt which was detected with ultrasound in an infant with a fatal congenital hypertrophic cardiomyopathy. An aberration in primitive vitelline venous development may have contributed to the formation of this unusual vessel.

    Computed tomography in neuronal ceroid lipofuscinosis (1980)
    Springer
    Neuroradiology 19 (1980), S. 35-38

    Notes: Summary The computed tomography (CT) findings in a verified case of neuronal ceroid lipofuscinosis (NCL) are presented. CT revealed diffuse and severe cerebral atrophy, reflected by generalized subarachnoid space enlargement and symmetric ventricular dilation. There was no evidence of abnormalities of the white matter. The CT features in our case of NCL correspond perfectly with the neuropathologic changes of the disease mentioned in the literature. Furthermore, CT is of considerable help in differentiating between those inherited metabolic brain diseases characterized primarily by white matter involvement and those presenting predominantly with changes of grey matter.

    CT of meningiomas on the posterior surface of the petrous bone (1981)
    Springer
    Neuroradiology 22 (1981), S. 111-121

    ISSN: 1432-1920
    Keywords: Meningioma, posterior fossa ; Computed tomography ; Cerebellopontine angle

    Notes: Summary A detailed analysis of the CT findings in 16 surgically verified cases of meningioma of the posterior surface of the petrous bone is presented. The results indicate that a correct preoperative diagnosis is possible in almost every case. Frequently occuring specific CT criteria for meningioma of the posterior surface of the petrous bone include: hyperdense, homogeneously enhancing, extra-axial, CPA mass; inverse relationship between precontrast attenuation value and degree of contrast enhancement of the tumor; oval shape; obtuse angle between lateral tumor border and posterior surface of petrous bone, and evidence of transcisternal supratentorial tumor extension. Infrequently occuring specific CT criteria include: tumor calcification; hyperostosis or exostosis of the posterior surface of the petrous bone; a comma-shaped tumor configuration in cases with transcisternal tumor extension and evidence of transtentorial tumor extension. Oxygen CT cisternography is the most sensitive and reliable technique for detecting small tumors. The CT differential diagnosis of meningioma of the posterior surface of the petrous bone is discussed.

    Functional diagnostics of the cervical spine using computer tomography (1988)
    Springer
    Neuroradiology 30 (1988), S. 132-137 
    Details
    ISSN: 1432-1920
    Keywords: Cervical spine ; Functional CT-scan ; Instability ; Fusion
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary 35 healthy adults and 137 patients after cervical spine injury were examined by functional CT. The range of axial rotation at the level occiput/atlas, atlas/axis and the segment below were measured in all subjects. A rotation occiput/atlas of more than 7°, and C1/C2 more than 54° could indicate segmental hypermobility, a rotation at the segment C1/C2 less than 29° to hypomobility. According to the postulated normal values based upon a 98% confidence level, out of 137 patinets examined after cervical spine injury and with therapyresistant neck pain, 45 showed signs of segmental hypermobility of the upper cervical spine, 17 showed hyper- or hypomobility at different levels, 10 patients presented segmental hypomobility at C1/C2 level alone. In all patients, according to the clinical assessment, functional pathology was suspected in the upper cervical spine. Surgical correction of rotatory instability should be considered as a possible therapeutic procedure after successful diagnostic stabilisation of the cervical spine by minerva cast.

    The value of functional computed tomography in the evaluation of soft-tissue injury in the upper cervical spine (1994)
    Springer
    European spine journal 3 (1994), S. 98-101 
    Details
    ISSN: 1432-0932
    Keywords: Functional CT scan ; Upper cervical spine ; Whiplash ; Axial rotation ; Alar ligaments
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary A functional rotatory computed tomography (CT) study of 423 whiplash patients with cervical spine soft-tissue injury was undertaken to determine its diagnostic value. The results are correlated with previous CT studies on normal subjects, and an evaluation of paradox motion, in which the lower vertebra rotates more than the vertebra immediately superior to it, is given. Asymmetrical left/right rotation reached the pathological value in 36% of the patient population at the level of CO-1. Twice as many patients had hypermobile rotation to the left as compared with the right, perhaps indicating that the right alar ligament is more often damaged in injuries involving the whiplash mechanism. A higher percentage of pathological values for hypermobile rotation was found at the level of CO-1 than at Cl-2. Patients exhibiting paradox rotation had a significantly higher amount of rotation to the contralateral side than did those who exhibited no paradox rotation. These findings validate the use of functional rotatory CT in the evaluation of soft-tissue damage of the upper cervical spine resulting from whiplash injury.
