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

    Notes: 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.

    Primary hepatic pheochromocytoma (1996)
    Springer
    European radiology 6 (1996), S. 82-85

    Notes: 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.

    MR findings in mannosidosis (1990)
    Springer
    Neuroradiology 32 (1990), S. 485-487 
    Details
    ISSN: 1432-1920
    Keywords: MRI ; Brain ; Sella turcica ; Mucolipidoses ; Mannosidosis

    Notes: Summary MR findings are reported in three patients presenting mannosidosis. Among a family of 8 children, 4 presented typical clinical and biological abnormalities related to mannosidosis. Brain MR examinations including sagittal T1 and axial T2 sections were obtained in three patients of this family (one 25-year-old male, one 34-year-old female, and one 35-year-old female). MR scans demonstrate seven types of modifications: (1) brachycephaly, (2) thick calvaria, (3) verticalization of the chiasmatic sulcus, (4) poor pneumatization of the sphenoid body, (5) partial empty sella turcica (6) cerebellar atrophy, and (7) white matter signal modifications. High signal abnormalities involving the parieto-occipital white matter are identified on axial T2-weighted scans in the three patients and are probably related to demyelination and associated gliosis as described previously by several authors on specimens.
