A 2 year old boy with humero-spinal dysostosis is described. This is the third case of this disease reported in the literature. Humero-spinal dysostosis is characterised radiologically by distal humeral bifurcation, elbow subluxation and coronal cleft vertebrae. Congenital, progressive heart disease, possibly with fatal outcome, is probably part of the syndrome.
A group of syndromes is presented whose common characteristic is the absence of pubic ossification at birth with very slow posterior mineralization. This is a radiological finding of interest as it has not been described in other entities. In all the cases shown, moreover, a variable degree of delay in bone age is observed. The increase of space between the pubic bones described in these syndromes is fictious, as it really signifies the existence of non-ossified cartilage. Therefore, they must be differentiated from those which deal with real widening of the symphysis of pubis.
Multiple clinical and radiological manifestations of Meckel's diverticulum are commented, presenting four cases with acute abdominal manifestations and one with chronic symptomatology, which were selected from a series of nineteen cases that were surgically verified. The authors realize a critique of the radiological techniques in the literature of the suspected cases of said entity.
A three-month old asymptomatic infant was incidentally found to have an abdominal mass. Through standard radiological and vascular procedures it was defined as being of hepatic origin, vascular etiology and of benign prognosis. Differences among cavernous hemangioma, hepatoma, metastasis and hemangio-endothelioma are summarized. The importance of angiography is emphasized as an essential procedure previous to the surgical evaluation and therapy.

Three cases are presented of eventual diagnostic errors concerning the thymus. In the first case right aberrating lobe appeared radiologically as a tumour of posterior mediastinum. In the second case, the large thymic malleability, enabled it to invade medium mediastinum and to show an extraordinary variability in shape when in decubitus. Finally, a post surgical hematomata, in a patient affected by a cyanogen cardiopathy actually showed some problems of radiological diagnosis with the characteristic thymus regeneration.
