Swollen ischiopubic synchondrosis: a dilemma for the radiologist.

Differences in size and shape of ischiopubic synchondrosis in childhood may present problems in diagnosis and differential diagnosis. Whereas asymptomatic swollen ischiopubic synchondrosis represents a normal ossification process, painful swelling is a symptom of underlying pathology. Five children are described with symptomatic ischiopubic synchondrosis swelling, four representing stress reaction and one with osteomyelitis. Radiologists should be careful when reporting on swollen ischiopubic synchondrosis in symptomatic children.

Metachondromatosis.

OBJECTIVES: To draw attention to metachondromatosis, which may be misdiagnosed as multiple osteochondromatosis, and to point out several findings that have not been emphasized in previous reports. PATIENTS AND METHOD: The authors reviewed the relevant clinical and detailed radiographic findings for five patients from different countries, who underwent imaging at various ages during childhood. RESULTS: Deformities resembling exostoses and punctate calcification were distinctive and represent previously unemphasized features of vertebral involvement in metachondromatosis. Widespread metaphyseal changes were best seen in the femoral necks, which were broad and showed prominent cartilage columns in all of the patients. Flattening of the femoral heads was observed in three patients; in one of these the flattening progressed to epiphyseal necrosis and coxa magna. In one patient the hands and feet showed no enchondromatous involvement. CONCLUSION: Metachondromatosis is a generalized bone dysplasia predominantly affecting the tubular bones and, to a lesser degree, flat bones and the vertebral column. Significant complications may include avascular necrosis of the femoral head and progressive deformity of the small joints due to expanding local exostoses. The typical involvement of the hands and the feet may not always be seen.

Crohn's disease penetrating into the spinal canal.

An 11-year-old boy who had suffered from Crohn's disease of the large bowel for 4 years developed high fever, severe back pain and flexion-contracture of the right hip joint with inability to walk. After several weeks radicular irritation also became apparent. CT-scan demonstrated an abscess of the right psoas muscle that had also infiltrated the spinal canal, leading to a spinal extradural abscess extending from L2-S4. Therapy comprised surgical drainage of the psoas abscess and conservative therapy (mainly steroids and hypercaloric diet) and resulted in complete cure of the psoas and the spinal abscess. Spinal infiltration is a rare and serious complication of Crohn's disease and must be considered in every case of significant back pain with or without obvious neurological signs.

Kidney dimensions in ultrasound compared to somatometric parameters in normal children.

In 196 children aged between 4 weeks and 16 2/12 years a sonographic investigation of kidneys was performed and put into relation to somatometric data including bodyweight (BW) bodylength (BL), length of the trunk and the upper and the lower limb, breadth of thorax and pelvic, head circumference, maximum cranial length and maximum cranial breadth. None of the children had signs of renal disorder. Morphometric data, as kidney length, width, depth, parenchymal areas in longitudinal and transverse sections and the prolate ellipsoid volume (PEV) were documented. The children were divided into five groups (group 1: 2-6 months, group 2: 6-31 months, group 3: 31-99 months, group 4: 99-131 months, group 5: 131-194 months). Mean values of all parameters were calculated. For each group a multiple regression analysis was performed and a regression equation of kidney length, parenchymal areas and volume was established. This method allows an individual determination of renal size and parenchymal mass.

Tumorous osteomyelitis. Report of two cases.

Two cases of chronic osteomyelitis with unusual Ewing's like X-ray changes are reported. Inspite of extensive investigations no causative organisms were found. The infection was resistant to different kinds of therapy. The authors suppose that the strange X-ray appearances may be due to an unusual localised immune response of the bone to an unknown, possibly viral agent.

[Differential diagnosis of a unilateral hyperlucent lung: the Swyer-James syndrome].

Lower respiratory infections in infancy caused lung emphysema in a 10-year old girl; being a locus minoris resistentiae the emphysema led to recurrent pulmonary complaints. This corresponds to the definition of the Swyer-James or McLeod Syndrome. The radiologic clue to the diagnosis is often the "unilateral hyperlucent lung", which is also found in many other childhood diseases. With our case we present an economical way of differentially diagnosing the unilateral hyperlucent lung, a way that is as little invasive as possible.

[Familial megacolon (author's transl)].

The genetic aspects of Hirschsprung's disease are discussed and there is a family incidence of 1 to 6%. Boys are more frequently affected. The mode of genetic transmission is not known. Three families with Hirschsprung's disease are reported with special reference to the transmission of Hirschsprung's disease.
