To determine the incidence, the operator's experience, and other variables that may influence the development of pneumothorax or re-expansion edema after ultrasound (US)-guided thoracocentesis. ⋯ US-guided thoracocentesis can be done equally as safely by residents as by senior radiologists. The safety and feasibility of the method are evident among mechanically ventilated intensive care patients. Our results do not support the routine use of post-thoracocentesis chest radiography.

An ectopic pituitary adenoma, exclusively involving the sphenoid sinus, associated with a normal size pituitary gland and an empty sella is a rare clinical entity. Only four cases have been found in the literature. ⋯ Computed tomography (CT) appeared to show expansion of the sellar floor inferiorly into the sphenoid sinus, and magnetic resonance imaging (MRI) demonstrated an empty sella and a mass lesion confined to the sphenoid sinus. The tumor was totally resected by taking a transnasal endoscopic approach and the dura mater of the base of the pituitary fossa was confirmed intact.

To review magnetic resonance (MR) diffusion-weighted imaging (DWI) and spectroscopy findings in patients with focal cerebral tuberculosis and to assess whether these techniques can adequately characterize focal cerebral tubercular lesions. ⋯ DWI and MR spectroscopy help in determining the nature of cerebral tubercular lesions; however, since the findings are varied, they do not help in specific characterization.

To describe magnetic resonance imaging (MRI) findings in patients with suspected Parsonage Turner syndrome and to emphasize the value of an additional whole body MR scan to improve specificity of this diagnosis. ⋯ Whole body turboSTIR MR imaging is a useful diagnostic tool in the evaluation of patients with suspected Parsonage Turner syndrome. Inclusion of the brain, neck, brachial plexus, and extremity musculature at whole body imaging allows differentiation from polymyositis and elimination of additional causes of shoulder girdle pain and weakness including gross lesions in the brain, neck, and brachial plexus by a single non-invasive study.
