Evaluation of the child with suspected spinal injury can be a difficult task for the radiologist. Added to the problems posed by lack of familiarity with the normal appearances of the paediatric spine is anxiety about missing a potentially significant injury resulting in neurological damage. Due to differences in anatomy and function, the pattern of injury in the paediatric spine is different from that in the adolescent or adult. Lack of appreciation of these differences may lead to over investigation and inappropriate treatment. This review attempts to clarify some of the problems frequently encountered. It is based on a review of the literature as well as personal experience. The normal appearances and variants of the spine in children, the mechanisms and patterns of injury are reviewed highlighting the differences between children and adults. Specific fractures, a practical scheme for the assessment of spinal radiographs in children, and the role of cross sectional imaging are discussed.

A 6-month-old boy presented with a large abdominal mass that proved to be a cystic hepatic mesenchymal hamartoma occupying both hepatic lobes. During fetal life, a bulky, abnormal, cystic placenta had been present, which on histological examination was diagnosed as mesenchymal stem villous hyperplasia. This association has not previously been reported.

We report a case of a bleeding Meckel's diverticulum where scintigraphic and sonographic findings were thought to suggest an ileal duplication. We are not aware of previous reports of sonographic imaging of an uncomplicated Meckel's diverticulum.

Infantile myofibromatosis is a rare condition which usually presents in childhood. It has a wide spectrum of disease activity, ranging from a solitary cutaneous nodule, through to a multicentric form with widespread visceral involvement. We present four cases which demonstrate the diversity of this condition and its radiological findings, together with a review of the literature.

Neospora caninum is a commonly diagnosed cause of reproductive losses in farmed ruminants worldwide. This study examined 495 and 308 samples (brain, heart and placenta) which were collected from 455 and 119 aborted cattle and sheep fetuses, respectively. DNA was extracted and a nested Neospora ITS1 PCR was performed on all samples. The results showed that for bovine fetuses 79/449 brain [17.6% (14.2–21.4)], 7/25 heart [28.0% (12.1–49.4)] and 5/21 placenta [23.8% (8.2–47.2)] were PCR positive for the presence of Neospora DNA. Overall 82/455 [18.0% (14.6–21.7)] of the bovine fetuses tested positive for the presence of N. caninum DNA in at least one sample. None (0/308) of the ovine fetal samples tested positive for the presence of Neospora DNA in any of the tissues tested. The results show that N. caninum was associated with fetal losses in cattle (distributed across South-West Scotland), compared to sheep in the same geographical areas where no parasite DNA was found. Neospora is well distributed amongst cattle in South-West Scotland and is the potential cause of serious economic losses to the Scottish cattle farming community; however, it does not appear to be a problem amongst the Scottish sheep flocks.
