    Notes: Abstract. Numerous diseases can lead to multilocular lesions of the liver. The authors report a rare pediatric case of hepatic granulomas due to Pasteurella multocida: a 7-year-old girl with chronic fever was investigated by sonography and CT scan, demonstrating mesenteric lymph node enlargement and numerous small hepatic lesions. After surgical biopsy, histopathology of the liver specimens showed pyogenic granuloma, with serologic testing positive for Pasteurella multocida. Treatment with a tetracycline and corticosteroids was successful. Pasteurella multocida infection, despite its habitual benign course, should be suspected among differential diagnoses of lymphogranulomatous affections with hepatic involvement. No case of liver and lymph node foci in a child has been previously described.

    Notes: Abstract. Hemophagocytic lymphohistiocytosis, a variant of histiocytosis, is characterized by an uncontrolled activation of the cellular immune system, including hepatic mononuclear phagocytic cells. Abdominal ultrasound findings in children are evaluated in this disease. We present six pediatric cases, two with familial and four with sporadic hemophagocytic lymphohistiocytosis, examined by abdominal sonography. Three signs were frequently observed: thickening of the gallbladder wall (all cases), increased periportal echogenicity (four cases), and enlarged lymph nodes in the porta hepatis (four cases). Hepatomegaly, splenomegaly, and ascitic fluid may also be found. These imaging findings are not specific and may be seen in viral hepatitis. However, once hepatitis is excluded, they may suggest the diagnosis of hemophagocytic lymphohistiocytosis in a critically ill child. A bone smear must be done to establish the diagnosis.

    Notes: Abstract Portal vein thrombosis is a rare but potentially lethal complication in children requiring splenectomy. We report on a 15-year-old boy with a dehydrated hereditary stomatocytosis, who underwent splenectomy and presented a postoperative partial portal vein thrombosis. With prompt heparin therapy, neither propagation of the thrombus nor further cavernous transformation in the following occurred 6 years. Conclusion Recent data suggest that hereditary stomatocytosis carries a high risk of thrombotic complications, especially after splenectomy. This procedure, the benefit of which is limited in this condition, should therefore be strongly avoided.

    Notes: Abstract Capillary haemangiomas are frequent benign tumours in infancy. The authors report a case of capillary haemangioma of the greater omentum, discovered in a child of 5 months of age and studied with US, CT and MRI. The localization of such a lesion in the greater omentum is exceptional. Abdominal US revealed a heterogeneous, multinodular intraperitoneal mass. Doppler study demonstrated hypervascularity of the lesion. CT localized the mass to the greater omentum. The mass was hypodense on the unenhanced scan and enhanced massively after injection. The infant suffered a reaction to contrast medium during the CT. MRI demonstrated a mass which was hypointense on T1-weighted images and hyperintense on T2-weighted images. Laparotomy confirmed the location of the mass within the greater omentum and allowed resection of the tumour.

    Notes: Abstract Aneurysmal bone cysts in the skull vault are reported in two patients 7 and 9 years old, who presented with vomiting and headaches caused by raised intracranial pressure. CT showed the cystic lesion in the diplo%e, with predominantly inward expansion. Fluid-fluid levels were seen on both CT and MRI; the latter also showed bleeding within the cyst. MR angiography showed compression of the superior sagittal sinus in the second case.
