    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.

    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.

    Percutaneous puncture of spinal cysts in the diagnosis and therapy of syringomyelia and cystic tumors (1982)
    Springer
    Neuroradiology 24 (1982), S. 59-63 
    Details
    ISSN: 1432-1920
    Keywords: Spinal cord ; Neoplasms ; Myelography ; Metrizamide ; Syringomyelia ; Cysts ; Computed tomography ; Chiari malformation

    Topics: Medicine
    Notes: 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.

    MR findings in mannosidosis (1990)

    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.

    CT findings in malignant meningiomas (1982)
    Springer
    Neuroradiology 23 (1982), S. 207-209 
    Details
    ISSN: 1432-1920
    Keywords: Computed tomography ; Meningiomas ; Brain neoplasms
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Recurrent meningiomas are due usually to incomplete removal as in the case of basal meningiomas where the tumour surrounding vessels and nervous structures cannot be completely excised. Recurrent meningiomas of the convexity are rare after resection. In most recurrent cases histological changes are noted which may explain the rapid growth, the aggressive nature and also the malignancy of the tumour. These changes include increased mitotic activity, necrosis and invasion of the adjacent brain parenchyma. CT findings in malignant meningiomas are related to the microscopic appearance of these tumours: tumoral necrosis determines heterogeneous enhancement; brain invasion explains the irregular outline of the tumour and sometimes the absence of surrounding low attenuation area. The authors report 5 malignant meningiomas in which the CT findings are correlated with the microscopic findings.

    Notes: Summary Symptomatic intrasellar Rathke's cleft cysts are rather rare: only a few cases with CT findings have been reported. The authors describe the CT appearance of 3. Histological aspects and embryology are discussed. Rathke's cleft cysts have to be differentiated from other intrasellar tumours: cystic craniopharyngiomas, cystic or necrotic pituitary adenomas, cysticercosis.

    Radiology of posterior lumbar apophyseal ring fractures: Report of 13 cases (1988)
    Springer

    Topics: Medicine
    Notes: Summary The authors report radiological findings in 13 cases of avulsion of the posterior lumbar apophyseal ring. The lesion affected young adults in 10 cases and adolescents in 3 cases. The lesion involved the inferior endplate of L4 in 11, and of L5 in 1 patient, and of L3 in 1 patient. 6 patients presented with unilateral sciatica, 3 with bilateral sciatica, and 4 with low back pain. Acute spinal trauma was evident only in 2 adolescents. Radiological recognition of the lesion was possible on plain films in 9 cases. CT demonstrates association of avulsion of the posterior vertebral apophyseal ring and herniated disc in all cases. Avulsion of the posterior apophyseal ring has to be differentiated from posterior longitudinal ligament, annulus, or herniated disc calcifications, as well as from posterior degenerative ridge osteophytes. Controversy about physiopathology of the lesion remains: weakness of the apophyseal ring during childhood and in patients with Scheuermann's disease may explain avulsion of the apophyseal ring in association with median disc herniation.

    Notes: Summary The authors report the CT scan findings in a case of sellar spine. This osseous spine which arises in the midline of the anterior aspect of the dorsum sellae and is directed toward the center of the sella turcica has already been described on specimens and on plain films but never on CT scans. The CT scan findings confirm the normal appearance of the surrounding structures.

    Anatomy and computed tomography of the normal lumbosacral plexus (1987)

    ISSN: 1432-1920

    Notes: Summary The main nerves of the pelvis and lower limbs arise from the lumbar and sacral plexuses. These nerves can be affected by any of a large number of pathologic processes that occur in the paravertebral and pelvic regions. Understanding of the neurological findings related to paravertebral and pelvic pathology needs complete and accurate knowledge of the anatomy of these regions. The axial transverse sections of computed tomography give perfect visualisation of the anatomy of osseous, muscular, and vascular structures of the vertebral and paravertebral area and pelvic walls. Visualisation of the nerves in this regions is much more difficult, because direct demonstration of nervous structures by computed tomography is usually impossible. To be able to identify components of the lumbosacral plexus on axial CT sections the radiologist has to know the location of the nervous structures and the relationships of these structures to vascular, muscular and osseous structures which are easily demonstrated.

    Notes: Summary The authors report three cases of lumbar apophyseal joint lipoma located at the L4/L5 or L5/S1 level. CT scan makes the diagnosis easily possible; indeed erosive changes with enlargement of the upper portion of the lumbar articular joint and anterior displacement of the top of the superior facet are associated with intra-articular fatty densities. Clinical symptoms are rarely encountered and may be related to narrowing of the upper portion of the intervertebral foramen.
