The use of an 'itinerant' expert witness in our civil courts used to be confined mostly to the field of forensic pathology, but has now become established in radiology. Doctors are often accused of closing ranks in malpractice claims against colleagues by a patient. In my experience, radiologists invariably have been balanced and responsible when asked to comment on malpractice issues ; in 40 years of practise, I have never seen or heard of a deliberate cover-up to protect a colleague's interestsabove those of a patient.

A 35-year-old man presented with a right chest wall mass. Chest radiographs revealed pleural thickening underlying a soft tissue mass which obscured the 5th to 7th ribs, and an expansile osteolytic lesion of the 7th rib. Ultrasound examination demonstrated a fluid-filled cystic lesion of the chest wall with intrathoracic extension.

Echinococcosis is an infection caused in humans by the larval stage of the Echinococcus parasite. Multi-organ involvement is common, and cysts may develop in various organs. Radiological imaging modalities play an important role in the diagnosis, management and follow-up of echinococcosis. We present a case of multi-organ echinococcosis with extensive pulmonary involvement.

Conjoined twins are rare variants of monozygotic twins. There are many types of conjoined twins, usually classified according to the site of fusion. The most common type of renal fusion anomaly is the horseshoe kidney, comprising two distinct functioning kidneys on either side of the midline, which are more likely to be connected at the lower poles. We report on a 30-year-old woman who presented to the antenatal clinic at Chris Hani Baragwanath Hospital, Soweto. Fetal magnetic resonance imaging revealed thoraco-omphalopagus conjoined twins with complexthoracic and abdominal structures, including a horseshoe kidney that was confirmed on postnatal computed tomography screening. Our patient was classified as a thoraco-omphalopagus type, with fusion of the thorax and the mid-trunk.

Vein of Galen aneurysmal malformation (VGAM) accounts for up to 30% of paediatric vascular malformations. As the internal cerebral veins develop, the anterior portion of the median prosencephalic vein of Markowski (MPM) regresses, and the posterior portion remains to form the vein of Galen. It is believed that the VGAM is the result of an arteriovenous connection between the primitive choroidal arteries and the MPM. The abnormal flow in these connections inhibits the involution of the MPM.

Short stature is a frequent presenting problem in the paediatric population.Various causes including endocrinopathies, skeletal dysplasias, dysmorphic syndromes and malabsorption have been implicated. In girls with short stature, Turner syndrome is frequently considered in the differential diagnosis and can easily be ruled out with chromosome analysis. However, it is not uncommon for a child to have no identifiable cause of their short stature.
