Congenital pseudarthrosis of the clavicle: a rare and challenging diagnosis.

Congenital pseudarthrosis of the clavicle is a rare clinical entity, first described in 1910. We report on a newborn baby girl who presented with a painless lump over mid-portion of right clavicle at her routine newborn examination, which was subsequently diagnosed as a congenital pseudarthrosis. Here we explore its pathogenesis, elaborate on its differential diagnoses in paediatric patients, and comment on its distinct radiological features.

Treatment of primary liver cancer using highly-conformal radiotherapy with kV-image guidance and respiratory control.

Purpose: To implement a reliable, practical and reproducible treatment procedure, based on in-room kV-image guidance and respiratory control, for liver cancer patients treated with high dose conformal radiotherapy using a commercially available treatment system.

Materials And Methods: CT stimulation was conducted under voluntary breath hold or gating using the Varian Real-time Position Management™ (RPM) System. Treatments were delivered daily under kV image guidance to verify the diaphragmatic or lipiodol-defined tumor position.

Thoracic spinal gout mimicking metastasis.

Gout is a common metabolic disease but spinal gout is rare. We report a case of gouty arthritis affecting the thoracic spine in a 76-year-old male patient with a long history of tophaceous gout who presented with bilateral lower limb weakness. Magnetic resonance imaging of his thoracic spine revealed erosions in the left pedicles of T8 and T10.
