    Evaluation of Blalock-Taussig shunts in newborns: value of oblique MRI planes (1991)
    Springer

    Notizen: Abstract Eight infants with systemic-pulmonary Blalock-Taussig shunts were evaluated by spin-echo ECG-gated MRI. Contrary to Echocardiography, MRI using coronal oblique projections successfully visualized all palliative shunts entirely in one single plane (including one carried out on a right aberrant subclavian artery). MRI allowed assessment of size, course and patency of the shunt, including pulmonary and subclavian insertion. The proximal portion of the pulmonary and subclavian arteries were also visualized. We conclude that MRI with axial scans completed by coronal oblique planes is a promising, non invasive method for imaging the anatomical features of Blalock-Taussig shunts.

    Notizen: Abstract. Recurrence of traditionally treated appendicitis is rarely reported but known to surgeons and is probably underestimated. We described a case, illustrated by CT, of stump abscess 2 years after laparoscopic appendectomy. Sonography and CT are helpful in detecting pericecal changes, but diagnosis is confirmed by laparotomy.

    Primary hepatic pheochromocytoma (1996)
    Springer
    European radiology 6 (1996), S. 82-85 
    Details
    ISSN: 1432-1084
    Schlagwort(e): Extra-adrenal pheochromocytoma ; Liver tumor ; CT ; MRI

    Thema: Medizin
    Notizen: Abstract Pheochromocytomas are uncommon tumors that represent a potentially curable cause of hypertension. They are usually located in the adrenal glands, but 10% arise from extra-adrenal sites, located along the paravertebral sympathetic chains. We report a case of primary hepatic pheochromocytoma responsible for a severe hypertension in a 24-year-old man. Echotomography showed a lightly heterogeneous mass located in the segment 8 of the liver. Iodine 131 — metaiodobenzylguanidine scintigraphy showed a large hepatic concentration of the tracer and no other localization. This tumor appeared highly vascularized on enhanced CT scan and on aortic angiography. Magnetic resonance imaging revealed a hepatic tumor with a high signal intensity on T2-weighted images and with a signal isointense to the liver on T1-weighted images. The hepatic venous sampling contained the highest catecholamine level, whereas the adrenal venous sampling was normal. After surgical resection of the hepatic tumor, the tension level and catecholamines plasmatic level normalized. No recurrent symptoms appeared during a 3-year follow-up.

    Notizen: Summary Five anatomical and radiological observations of a spine protruding into the pituitary fossa are reported. This osseous spine, about 4 mm long, arises in the midline from the inferior part of the anterior aspect of the dorsum sellae and extends upward and forward. The possible origins of this malformation are discussed.

    Frontal horn coarctation: CT demonstration (1979)
    Springer
    Neuroradiology 18 (1979), S. 217-219 
    Details
    ISSN: 1432-1920
    Schlagwort(e): CT ; Ventricular coarctation ; Ependymal fusion
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary The CT aspects of frontal horn coarctation by ependymal fusion in two cases are described with post-mortem verification. These ependymal fusions in the lateral ventricles are seen frequently on air ventriculograms, especially in the occipital horns. Ependymal fusions in the frontal horns are rare and not very well known. These fusions are clearly seen on CT and post-mortem examinations. The frontal horns appear asymmetrical on CT and this asymmetry evokes frontal horn compression (by an isodense tumour for instance), or contralateral frontal horn dilatation. Some CT details of ventricular coarctation make it easy to differentiate tumoural compression from controlateral subcortical atrophy.

    Percutaneous puncture of spinal cysts in the diagnosis and therapy of syringomyelia and cystic tumors (1982)

    Thema: Medizin
    Notizen: Summary The experience with percutaneous puncture of intraspinal cystic lesions is reported in four cases: an extradural cyst demonstrated with air, a spinal cord tumor with lipiodol and two cases of syringomyelia with metrizamide. Percutaneous puncture of cystic lesions makes possible an accurate delineation of the lesion and a histological approach through biochemical and cytological analysis of the aspirated cystic fluid, while aspiration of the fluid of cystic tumors decompresses the spinal cord and thus plays a therapeutic role.

    Notizen: Summary A case of metastasis to the thoracic spinal subdural space is reported. Metrizamide myelography showed narrowing of the upper thoracic subarachnoid space. A tumor in the spinal subdural space is unusual; only a few cases have been reported. The myelographic appearance is not specific; an epidural metastasis can produce the same myelographic picture.

    CT follow-up of microprolactinomas during bromocriptine-induced pregnancy (1983)
    Springer
    Neuroradiology 25 (1983), S. 133-138 
    Details
    ISSN: 1432-1920
    Schlagwort(e): Prolactinoma ; CT ; bromocriptine ; pregnancy
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary In the last few years complete or partial regression of prolactinomas has been demonstrated in nonpregnant women treated by bromocriptine. Thus bromocriptine therapy appears as an attractive alternative to surgery for management of infertility related to hyperprolactinemia. However, numerous reports emphasized the possibility of an excessive growth of the pituitary adenoma with visual field defects during the last 3 months of pregnancy. To avoid these complications, the authors followed with serial CT scans the growth of microprolactinoma at the 5th or 6th month of pregnancy. Among six pregnant women, one patient presented a marked upward extension of the adenoma. Bromocriptine was then reintroduced and the effectiveness in reducing tumor growth was proved by CT scan at the 7th month. Regarding low risk of using intravenous iodinated contrast medium in pregnant women and of fetal radiation damage, the authors emphasize the value of CT in the follow-up of bromocriptine-induced pregnancies.

    Multiple sclerosis and corpus callosum atrophy: Relationship of MRI findings to clinical data (1988)
    Springer

    ISSN: 1432-1920
    Schlagwort(e): Multiple sclerosis ; Magnetic resonance imaging ; Corpus callosum atrophy

    Thema: Medizin
    Notizen: Summary Among 110 patients (45 men, 65 women), aged 15 to 66, with clinical and/or biological diagnosis of multiple sclerosis (MS), severe to moderate corpus callosum (CC) atrophy was observed in 67 (60%) patients. Correlation between CC atrophy, brain atrophy, duration and severity of clinical symptoms, and high signal white matter areas, was carried out in 90 patients. Mean age was 46 years for those with severe CC atrophy, and 33 years for those without atrophy. Mean duration of the disease was 14 years in patients with severe atrophy, and 5 years in patients without atrophy. Severity of clinical symptoms is more pronounced in patients with severe CC atrophy. Numerous or large white matter high signal areas are observed in patients with severe CC atrophy on T2-weighted images. CC atrophy appears earlier than brain atrophy in the course of MS.
