    Notes: Summary We present a retrospective study of occult spinal dysraphism in 47 children aged 0 to 14 years, all studied with plain X-rays, 60% with CT and myelo-CT, and 40% with MR. We consider the classification and grading of these malformations, clinical, neuroradiological patterns, and indications for surgery. In the light of our findings and of the published data MR emerges as the key investigation. Only in a few cases of great anatomical complexity is it now necessary to perform CT and myelo-CT as well. A case in point is when the conus and thickened filum terminale are inextricably bound together and can no longer be considered separate structures. We propose the term “neurofibrous structure” to define the conus-thickened-filum-terminale unit when these structure are no longer distinguishable.

    Role of haematological, pulmonary and renal complications in the long-term prognosis of patients with lysinuric protein intolerance (1993)
    Springer
    European journal of pediatrics 152 (1993), S. 437-440

    Notes: Abstract Three patients with lysinuric protein intolerance are reported. The first patient displayed severe haemolytic anaemia, bone marrow erythroblastophagocytosis, renal tubular disease and interstitial lung disease. Despite treatment with citrulline and low-protein diet, this child died at the age of 18 months. The second patient is now 24 years old and has chronic interstitial lung disease and focal renal glomerulosclerosis. The third patient, now 5 years old, has severe chronic interstitial lung disease. A 6-month treatment with prednisone was ineffective in the second and third patients.

    MRI of hepatic focal nodular hyperplasia: A report of two new cases in the pediatric age group (1990)
    Springer
    Pediatric radiology 20 (1990), S. 267-269 
    Details

    Topics: Medicine
    Notes: Abstract At present, magnetic resonance is a useful modality for the diagnostic assessment of focal nodular hyperplasia of the liver. In the pediatric age group, diagnosis for this kind of pathology is more effective and conclusive when performed by MR, because of the limited variety and the restricted expression of primary hepatic tumors. MR diagnosis is based on the presence of a central connective tissue that is scar hyperintense on T2-weighted sequences, which can be regarded as a typical finding, though not specific. The other criteria used to differentiate it from primary malignant tumors on MRI are the homogeneity of the tissue surrounding the scar and its signal intensity, which is similar to that of adjacent normal hepatic parenchyma.

    CT of invasive pulmonary aspergillosis in children with cancer (1993)
    Springer

    Notes: Abstract In treating cases of malignancy, the use of chemotherapy carries a high risk of lower respiratory tract infections, especially fungal pneumonopathy. This complication is a major cause of mortality and is often difficult to diagnose because of non-specific clinical or radiological changes, but the early recognition of invasive fungal disease is imperative. CT is an important non-invasive method for the detection and evaluation of opportunistic fungal infections. In these patients an improved survival rate can be achieved when early detection by CT leads to the prompt institution of high-dose antifungal therapy. We illustrate the spectrum of CT findings of invasive pulmonary aspergillosis encountered in children with cancer. These patients had previously been treated with highdose chemotherapy with or without bone marrow rescue, and underwent radiological examinations because of clinical evidence of pneumonopathy. Representative cases demonstrate the clinical applications of CT in the evaluation and management of invasive fungal disease.

    MRI “road-map” of normal age-related bone marrow (1995)
    Springer
    Pediatric radiology 25 (1995), S. 588-595 
    Details
    ISSN: 1432-1998

    Topics: Medicine
    Notes: Abstract We retrospectively reviewed 733 cranial and 250 spinal T1-weighted MR images of patients younger than 24 years to evaluate the bone marrow changes. The signal intensity of the bone marrow on short-TR/TE images was compared with that of fat and normal muscles in the contiguous region and graded. The signal intensity of all anatomic segments was as low as that of muscle, or inferior, in all patients younger than 3 months because of hematopoietic tissue and probably greater amounts of trabecular bone. The first anatomic segments of cranial bone to become hyperintense were the zygomatic bone and mandibular symphysis, followed by the presphenoid bone, basisphenoid, basiocciput, calvaria, and the petrous apex. After 3 years of age, most patients demonstrated pneumatization of the sphenoid sinus. We describe the most interesting changes in the developing spien, which occur in the first 2 years of life. The morphology of the vertebral bodies was evaluated. The variability of the signal and the morphology of the disks were also evaluated. Regional patterns of bone marrow signal intensity and age-related differences should not be misinterpreted as a pathologic condition.

    Relapsing polychondritis in childhood: A rare observation studied by CT and MRI (1992)
    Springer

    Notes: Abstract Relapsing polychondritis is very rare in children. The diagnosis must be based on a combination of clinical and pathologic features. CT is very useful for an accurate and rapid assessment of laryngo-tracheo-bronchial involvement and the typical finding is lumen narrowing by wall thickening and collapse of the supporting cartilaginous structures. The role of MR imaging should be complementary to CT.

    Mucopolysaccharidosis: thickening of dura mater at the craniocervical junction and other CT/MRI findings (1993)

    Notes: Abstract Cranial CT and/or MRI imaging of 8 patients with mucopolysaccharidosis (MPS) was retrospectively evaluated. Two patients had MPS IH, 1 had MPS IS, 1 had MPS IVA and 4 had MPS IV. CT and MRI showed thickening of dura mater at the cranio-cervical junction, causing narrowing of the subarachnoid space, in all the patients examined. Spinal cord compression was detected in 4 patients. Other findings were: white matter alterations, mild to severe hydrocephalus, skull dysplasia and odontoid dysplasia. White matter alterations were evident as large areas and as multiple dispersed spots of prolonged T1 and T2 value. Reduced gray/white matter contrast was demonstrated on T2-weighted MRI images. It is important to examine the cranio-cervical junction carefully for thickening of dura mater in all patients with mucopolysaccharidosis examined by CT or MRI, because of the generally progressive clinical course of MPS. In patients with symptomatic cord compression, surgical intervention should be considered.

    Leiomyomatosis of oesophagus, congenital cataracts and hematuria (1991)

    Notes: Abstract Isolated oesophageal leiomyomatosis in children is very rare. The association between leiomyomatosis of oesophagus and female genital tract and an Alport like hematuric nephritis has been recognized as a distinct entity by Garcia-Torres and Guarner [1]. Since then few other cases of this syndrome have been observed. Congenital cataracts and neurosensory deafness have been added to the clinical spectrum. Autosomal dominant inheritance is suggested by the familial cases. We report a patient who presents, as a new finding, leiomyomatosis of the rectum.

    An unusual CT presentation of congenital cerebral toxoplasmosis in an 8 month-old boy with AIDS (1992)

    Notes: Abstract We report on a 8-month-old boy with AIDS, born of an asymptomatic mother with positive HTLV-III serology. He was hospitalized in the Intensive Care Unit because of anemia, fever and hepatosplenomegaly. Chest X-ray showed pneumonia and subsequent blood cultures were positive for Candida albicans. After 3 days of Amphotericine B treatment, the patient was transferred to Infectious Disease Department. After 30 days of hospitalization, the patient developed a rapid neurological impairment evolving into coma. CT scan showed a round, ringshaped low density lesion with hypershaped low density lesion with hyper-dense and enhancing haemorragic centre in the left basal ganglia and a smaller hypodense lesion on the right. There was also evidence of cortical atrophy and mild ventricular dilatation. Such lesions are more commonly described in children with AIDS and congenital cytomegalic inclusion virus (CMV) encephalitis. In this case toxoplasma cysts were shown microscopically reinforcing the contention that in patients with AIDS, toxoplasma gondii infection may occur with atypical manifestation.
