Cystic Optic Chiasm Lesion: Atypical Magnetic Resonance Imaging Findings.

Intrinsic cystic lesions in the optic chiasm are an uncommon cause of bitemporal hemianopia compared with compressive lesions extrinsic to the chiasm. A 40-year-old man presented with difficulty driving. Clinical assessment revealed a bitemporal hemianopia.

Radiological predictors of recurrent primary spontaneous pneumothorax following non-surgical management.

Background: Studies to date have not identified any reliable predictors for recurrence of primary spontaneous pneumothorax (PSP) on plain chest radiograph (CXR). The aim of this study was to assess whether abnormalities on CXR at first presentation of PSP can be used to predict recurrence of PSP.

Method: The study included all patients admitted to The Canberra Hospital between 1998 and 2004.

Predicting outcome in term neonates with hypoxic-ischaemic encephalopathy using simplified MR criteria.

Background: MRI is an established investigation in the evaluation of neonates with suspected hypoxic-ischaemic encephalopathy (HIE). However, its role as a predictor of neurodevelopmental outcome remains complex.

Objective: To establish reproducible simplified MR criteria and evaluate their role in predicting neurodevelopmental outcome in term neonates with HIE.

Intrapleural nasogastric tube insertion.

A misplaced fine-bore nasogastric tube (NGT) might enter the bronchial tree. Pleural puncture and intrapleural passage of the tube is very uncommon but the location can often be inferred from the frontal chest radiograph. Following recognition of a NGT within the pleural space, progress films should be carefully screened for complications, particularly pneumothorax.
