Butler-Albright's distal tubular acidosis was confirmed by ultrasound imaging in the neonatal period, image characteristics showing persistent medullary hyperechogenicity. This case is remarkable by the very early-stage diagnosis of the nephrocalcinosis.
Osteitis of the forearm due to Nocardia asteroides was noted in an 8 year old tunisian boy 14 months after an open fracture. This observation of direct inoculation of bone by Nocardia asteroides was atypical because of the remarkable nature of the hyperostotic reaction.
Three patients presented with atypical subacute epididymal disorders diagnosed clinically as a scrotal tumor. Ultrasound imaging provided satisfactory morphologic data on lesions. Cold surgery was performed, either because of major functional disturbance (multiple epididymal abscesses) or because of doubt with respect to diagnosis (spermatic granuloma and epididymal hematoma). Castration was the final procedure in each case. Even though this surgical attitude appears logical because of the serious nature of the lesions, the revised clinical diagnosis provided by ultrasonography and the very good correlation between pathologic and ultrasonic findings should lead to a more eclectic therapeutic attitude in other cases.

The authors study the long term course of 37 cases of purulent arthritis of the limbs in the child, for which complete radiological documents covering a period of more than a year were available. They describe in particular the sequelae observed in 25 cases, classifying them by joint and by increasing order of severity. They then attempt, in the light of their own findings and of other published series, to draw conclusions concerning the main factors in prognosis--the age at the time of onset of the arthritis, the treatment given and the joint involved. The prognosis is all the more gloomy when a newborn or young infant is involved, when there is a delay before treatment is started or in the absence of joint aspiration-drainage and when the hip is affected.

Fifty-five consecutive case-reports of patients with evidence of confirmed biliary tract dilatation on ultrasound imaging were reviewed retrospectively to assess value of combined indirect ultrasound signs and simple biologic data in determining etiologic diagnosis. The diagnostic value of certain groups of signs representing indicators of tumoral or nontumoral lesions was equal or superior to that of direct visualization of the occlusion.

Mycotic aortic aneurysms were detected in four men aged between 47 and 73 years. The infective nature of the lesion was obvious in one case, while in the other three cases the diagnosis was suspected after radiological examination and confirmed by pathological and bacteriological investigations of the aneurysm wall. Radiological signs which suggest the presence of an infective aneurysm include rupture of the aneurysm, a rapidly progressing course, and unusual locations or morphology. Diagnosis is important as therapy differs from that of other types of aneurysm.
Two cases of cockayne's syndrome occurring in the same family group are reported. The authors describe the chronological evolution of the bone lesions, based on radiological examinations of the older sister made at 4, 13 1/2, and 15 years of age. Evidence that clinical signs of early ageing are associated with a rapid drop in thymic hormone levels led the authors to search for radiological signs of premature ageing. At 15 years of age only minimal signs were apparent.
