[Febrile osseous pain in children with sickle cell disease: MRI findings].

PURPOSE: The aim of this study was to report the MRI findings that can suggest a vaso-occlusive crisis in cases of febrile osseous pain in children suffering from sickle cell disease. MATERIALS AND METHODS: MRI (T1 and T2 weighted sequences and T1 weighted sequence with fat saturation before and after gadolinium injection) was performed in 10 children with sickle cell disease, presenting with febrile osseous pain. The diagnosis of vaso-occlusive crisis was made after fast improvement due to symptomatic treatment and negative bacteriological result. RESULTS: MRI was abnormal in all cases. A multifocal localisation was found in 2 cases. Bone marrow abnormalities were constant. In 10 cases, high T1 and T2 signal and metaphyso-diaphysial lesions were noted. Heterogeneous medullar enhancement with "ink stain" feature was constant. Early periosteal abnormalities were noted in 8 cases with inflammatory or stratified features. Cortical thinning was found in 1 case. Soft tissue abnormalities were observed in 5 cases with inflammatory features in 4. CONCLUSION: Multifocal synchronous localisation, medullar abnormalities resulting from hemoglobin degradation, heterogeneous enhancement, early periosteal abnormalities and associated soft tissues swelling are MRI findings suggesting acute vaso-occlusive disease.

[Fetal digestive tract pathology, imaging findings in antenatal diagnosis].

Foetal anomalies of the digestive tract are numerous and dominated by malformations, the prognosis of which may be severe. Antenatal diagnosis of these anomalies allows a better management of neonates. It is known since about 20 years, a major development because of the progress realized in the field of foetal imaging. Ultrasonography, which is the best imaging modality, can be joined by MRI if necessary. The objective of this study is to evaluate the contribution of imaging in prenatal diagnosis of digestive anomalies, throughout a review of literature.

[Pulmonary sequestration. Particular clinical and radiological features].

Bronchopulmonary sequestration is a rare malformation. Is characterized by non-functioning lung tissue fed from one or several aberrant systemic arteries. Authors present a 5-month-old boy with Hirschsprung disease in whom intralobar sequestration was fortuitously made on the occasion of pneumopathy. Sequestration with associated Hirschsprung disease is exceptional and not reported in the literature.

[Spinal vascular malformation in a child, revealed by lumbar puncture].

Spinal vascular malformations are exceptional in children. We report a case in 1 year-old patient due to a spinal vascular malformation which was revealed by paraplegia after lumbary punction. The diagnosis was made by MRI. Spontaneous outcome was characterised by the persistence of paraplegia.

[Acute osteomyelitis in children: early MRI diagnosis].

PURPOSE: To assess the value of MRI for early diagnosis of osteomyelitis in children presenting with sepsis and acute onset of musculoskeletal pain. MATERIALS AND METHODS: MRI including fat suppressed T2W, and fat suppressed pre- and postcontrast T1W sequences was performed within 48 hours of admission in 26 children with clinical (fever and acute musculoskeletal pain) and biological (elevated WBC count and ESR in all cases, and elevated CRP in 12 patients) suspicion of acute osteomyelitis. None of the patients had sickle cell disease. RESULTS: MRI was normal in 7 children (26%). Bone marrow signal abnormality was noted in 19 cases (74%) consistent with acute osteomyelitis in 18 cases and metastatic neuroblastoma in 1 case. CONCLUSION: MRI is useful for evaluation of children presenting with sepsis and acute musculoskeletal pain, early diagnosis of osteomyelitis and to prevent unnecessary hospital admission and work-up.

[Radiological signs of type I primary hyperoxaluria].

The authors report the radiological signs observed in 14 patients between the ages of 3 months and 16 years, suffering from type I primary hyperoxaluria. Four of these patients were being treated conservatively for renal failure and ten had reached end-stage renal failure. Stones were demonstrated in 9 patients. Nephrocalcinosis was present on the plain abdominal x-ray in 6 patients before dialysis, and in all patients dialysed for more than 3 months. Bone signs characteristic of type I primary hyperoxaluria were only observed in children with end-stage renal failure. Metaphyseal dense bands were revealed in 5 patients. Metaphyseal clear bands, observed in 4 patients, occurred later and appeared to replace dense bands which moved towards the diaphysis. The other signs detected were osteosclerosis of the vertebrae and ilium (4 patients) and epiphyseal subchondral clear bands (one patient).

[An exceptional combined malformation: duplication of the lower urinary tract, the vulva and the posterior intestine].

The authors report the case of a 6 year old girl with bladder duplication, urethral duplication, genital system duplication associated with colonic duplication and low double anorectal anomalies. This patient presented two hemivertebrae at T9 and T11. This girl died a few days after admission from internal obstruction and septicemia. The embryological features especially the possibility of associating two different embryopathogenic mechanisms in the pathogenesis of this combined malformation (Split notochord syndrome and fissure of the urogenital system), and diagnostic and therapeutic aspects are studied in relation to this case and a review of the literature.

[Peroperative sclerosis].

Complete, rapid destruction of the insufficient surface network as a one-stage procedure constitutes the best method for prevention of trophic disorders and especially pigmentation. Marked, rapid regression is obtained when these have unfortunately become installed. Combined surgery and multiple peroperative injections of a sclerosant allows the exclusive use of a gently acting sclerosant, 66% glucose solution, which is particularly well tolerated.

[66% glucose, a safe sclerosant. Experimental study].

Although accidents due to the intra-arterial injection of detergent sclerosant are very rarely observed, they are dramatic in their effects and often result in amputations, a risk accepted with difficulty for a treatment with a functional aim. To avoid these incidents, which may occur even when treatment is applied by the most experienced surgeons, the authors have used 66% glucose solution without accident since 1948. To confirm efficacy of the method, an experimental study compared 66% glucose (66 G) with a very commonly used product, 1% sodium tetradecyl sulfate (STD), in the rabbit. Except when enormous doses of 66 G are employed, the only effect noted was eosinophilic necrosis of the vessel wall without clinical symptoms, whereas doses eight times lower of STD produced an irreversible ischemia from obliterating endarteritis of the branches of the vascular tree injected. The 66% glucose solution appears to be a very safe, gently acting sclerosant, and the product of choice for peri- and post-operative sclerosis, particularly in regions where accidental arterial puncture is anatomically possible.

[Tuberculosis of the knee: MRI findings in two pediatric cases].

Osteo-articular tuberculosis is rare in infants. The MRI findings reported for adolescents and young adults mainly relate to spinal involvement. Two cases of osteo-articular tuberculosis of infants located at the knee are presented. Vaccination has been correctly done. Skin test and chest radiography were normal. Evolution was insidious for one case. Osseous, medullary, cartilaginous and soft tissue abnormalities revealed by MRI were suspicious for tuberculosis. Diagnosis was confirmed at histology for both cases and bacteriology for one case. The aim of this study is to report the MRI features of osteo-articular tuberculosis in pediatric patients.

[Peroperative multi-sclerosis using 66% glucose. Treatment of choice and best prevention of pigmentations of venous origin].

The complete and rapid destruction, at the one time, of the incompetent surface venous network is the best form of prevention of trophic changes, in particular pigmentation and leads to a marked and rapid regression of these lesions when they are already present. The combined method, associating surgery and peri-operative multi-sclerosis, allows the use of a gentle sclerosant, 66% glucose, which is particularly well tolerated.
