    Notes: Abstract The authors report 18 cases of pelvic rhabdomyosarcomas in children examined at presentation and followed on US and CT. There were 11 boys, 7 girls; tumor location was bladder, prostate or uterus in 12, perineum in 4, buttock in 2. US is good to define tumoral extension within the bladder CT is better to delineate the extension outside the bladder and regional spread to iliac nodes. CT is the only useful examination for perineal tumors. During chemotherapy US can be frequently repeated to appreciate tumoral regression and to give measurement of the mass. Preoperative CT should be performed when tumoral regression seems sufficient to permit complete tumoral excision without pelvic exanteration. Correlation between US and CT and surgical findings proved to be good. US and CT are also very useful in the follow-up when the child has finished treatment as it can demonstrate a local recurrence before clinical symptoms appear. However, post-surgical and post-radiation changes may be difficult to recognize. These aspects are discussed.

    Ultrasonography and computed tomography for diagnosis and follow-up of biliary duct rhabdomyosarcomas in children (1987)

    Notes: Abstracts The authors report eight cases of biliary duct rhabdomyosarcoma in children, examined by US and CT. There were five boys and three girls, aged 2 to 17 years. At presentation, US demonstrates the tumor mass within the liver or the hepatic hilum; it allows measurement of it and defines the relationship with portal vessels, biliary tract and other important structures. CT complements the US evaluation and determines operability. As US and CT cannot assess the histological origin of the tumor, a biopsy is mandatory before treatment. If complete surgical excision does not seem possible, percutaneous biopsy is preferrable to incomplete excision and its possible complications. During the follow-up period, US can be repeated to measure tumor regression under chemotherapy. After surgery, CT seems preferable because of gas interposition. Both US and CT proved to be valuable for the early detection of local recurrence. The prognosis of these tumors remains bad. However, with more aggressive and hopefully more efficient chemotherapy a precise evaluation of the tumor extension by US and CT is very important. Surgery will then be performed only on localized tumors or on residual masses after chemotherapy.

    Soft tissue signal abnormality associated with eosinophilic granuloma (1994)

    Notes: Abstract Six patients with eosinophilic granuloma were studied retrospectively in order to correlate the MRI appearances with the pathology. Ages ranged from 2 years 6 months to 11 years. The bones involved were the humerus, ulna, radius, femur, clavicle and ilium. Plain films, MRI and pathology specimens were obtained. A lytic lesion with indistinct margins, endosteal erosions and periosteal reaction was seen in all cases on plain radiographs. Bone marrow signal was decreased on T1-weighted images and increased on T2-weighted images throughout the bony lesion in all cases. T2-weighted images showed extensive soft-tissue abnormalities suggesting inflammatory changes in four cases. In two cases abnormalities were limited. Extensive changes correlated histologically with an early phase lesion. Localized minor changes were associated with a mid-phase lesion. Inflammatory soft-tissue changes could be associated with eosinophilic granuloma. The size of the soft tissue mass correlated well with the activity of the bony lesion.

    Notes: Abstract To evaluate the information obtained by magnetic resonance (MR) imaging, the radiographic and MR investigations of nine patients treated for idiopathic tibia vara were reviewed in retrospect. There were six unilateral and three bilateral cases (12 tibiae). Initial radiographs of each patient were assigned a stage according to Catonné's classification. MR imaging was performed with a 0.5- or 1.5-T apparatus. Bony epiphyses were poorly developed in all cases. The cartilaginous component of the epiphyses compensated partially (6/12 cases) or completely (6/12 cases) for the collapse of the physes. In two cases an abnormal area was found between the medial meniscus and the cartilaginous portion of the epiphysis. An abnormally large medial meniscus was noted in four cases; an abnormal signal in the medial meniscus was seen in two cases. MR imaging has several advantages over plain film: it uses no ionizing radiation, it shows the shape of the ossified and cartilaginous epiphysis, and it demonstrates meniscal and physeal abnormalities. MR imaging may influence the choice of treatment.

    A case of perforated cystic duplication of the transverse colon (1998)

    Notes: Abstract A 7-year-old girl presented with an abdominal cystic mass close to the pancreas. US and CT could not identify its origin. The diagnosis of duplication of the transverse colon was made at surgery. This location is rare. The differential diagnosis in this case included a pancreatic cystadenoma, a pseudocyst or a mesenteric cyst.

    Legg-Perthes-Calvé disease: Staging by MRI using gadolinium (1994)

    Notes: Abstract Twenty-one patients (26 hips) with typical signs of Legg-Perthes-Calvé (LPC) disease on plain radiographs were explored by MRI. Patients were imaged with a 0.5 T MR unit. Gadolinium-enhanced spin-echo MR images were obtained after nonenhanced T1-weighted (spin-echo) and T2*-weighted (gradient-echo) images. Four different areas were identified in the femoral epiphysis (necrosis, regenerative, cartilaginous and normal fatty bone tissue). The histological evolution of LPC is well described by Catterall and others. Comparing their descriptions with our MR findings, we suggest classification of LPC into five phases: necrosis: regeneration, reconstruction, reossification and sequelae.

    A case of intramedullary haematoma associated with congenital α 2-plasmin inhibitor deficiency (1998)

    Notes: Abstract The association of intramedullary haematoma of the left femoral diaphysis and congenital α2-plasmin inhibitor deficiency in a 6-year-old boy is reported. Congenital deficiency of this fibrinolytic system component is very rare and can result in severe bleeding. Clinically, an intramedullary haematoma causes pain but no swelling, and there is no history of trauma. X-rays show a hyperlucent lesion without sclerotic edges in the medulla of the diaphysis of a long bone with thinning of the cortex. MRI is diagnostic with the haematoma generating a specific hyperintense signal on T1-weighted and T2-weighted spin-echo images.

    Notes: Abstract Four patients who presented with predominant or exclusive face and orbital involvement by de Toni-Caffey's disease are reported. Facial manifestations of infantile cortical hyperostosis may be the first and sometimes the only manifestation of the disease. A mandibular involvement is almost always present and its characteristic appearance leads to the diagnosis of de Toni-Caffey's disease.
