ABSTRACT
AIM: The aim was to evaluate laser photocoagulation and the use of the Bonopty needle system in the treatment of osteoid osteoma. MATERIALS AND METHODS: Five patients with osteoid osteomas were treated with computed tomography (CT)-guided, percutaneous laser photocoagulation using the Bonopty biopsy system. RESULTS: Complete pain relief was obtained in four patients. In one patient, pain persisted until the 6 weeks follow-up but resolved within 24 h of repeating the procedure. There were no complications, and patients remained symptom free at follow-up of 4-23 months (mean, 14 months). CONCLUSION: CT-guided laser photocoagulation of osteoid osteoma is a minimally invasive technique that represents a cost-effective alternative to surgical excision. The Bonopty needle system allows successful penetration of the sclerotic bone surrounding the nidus with manual pressure alone.

Intra-articular ganglion cysts of the knee joint are rare. Percutaneous aspiration of ganglion cysts of the knee, which has both diagnostic and therapeutic value, has been described, but usually under guidance by computed tomography (CT). We describe ultrasound-guided aspiration of posterior cruciate ligament cysts in two patients.

Visualization of pre-cervical soft tissue swelling on a lateral radiograph is an important indicator of possible bony injury in the context of cervical spine trauma. We report a case where apparent swelling was in fact an artefact due to an inappropriately placed endotracheal tube. We recommend review of the position of endotracheal tubes when interpreting pre-cervical soft tissue swelling.

Isolated fracture of the sternum is an uncommon injury in a child. We report two cases of sternal fracture following falls from swings, which illustrate the mechanisms of injury in sternal fracture. One fracture resulted from a flexion compression injury of the thoracic spine, which has very rarely been reported in children. Sternal fracture should be considered in the differential diagnosis of acute chest pain in a child where there has been an activity involving hyperflexion force.

We report a case of pharyngoesophageal (Zenker's) diverticulum in a 91-year-old woman. Sonography of the thyroid gland showed diffuse enlargement of the gland and a well-defined, heterogeneous hyperechoic mass that appeared to be in the posterior left lobe. The mass had a smooth hypoechoic wall with a layered appearance anteriorly. Real-time sonography performed during the patient's ingestion of water showed transient changes in the size, margins, and echogenicity of the lesion, which subsequently reverted to its original appearance.

We report on a case of a deforming arthropathy in a young man with a lysosomal storage disorder. A 31-year-old man with a known diagnosis of mannosidosis presented with a painful swollen right elbow. Radiographs of his right elbow showed a disorganised joint with multiple fragments resembling the appearances of a neuropathic joint. This case provides further evidence that a deforming arthropathy may occur as part of the spectrum of skeletal abnormalities seen in mannosidosis.
