Case ReportsBarium aspiration showing crazy-paving appearance on high-resolution computed tomography.
We encountered a case showing a crazy-paving appearance on high-resolution computed tomography (HRCT), which mimicked various pulmonary diseases, e.g. pulmonary alveolar proteinosis, or non-specific interstitial pneumonia, but which we ultimately determined to be due to barium aspiration. The initial radiological findings were considered to be most likely due to pulmonary alveolar microlithiasis, because the crazy-paving appearance had high density, resembling calcification. ⋯ Since a barium swallowing study had been performed 2 weeks before the CT examination, and since the follow-up HRCT showed improvement we reached a diagnosis of barium aspiration. Although barium aspiration may yield findings similar to other diseases with crazy-paving appearance, it is possible to identify it because of the limited distribution and high density.

ReviewUsefulness of muscle denervation as an MRI sign of peripheral nerve pathology.
Peripheral nerve disorders may be classified into compressive or entrapment neuropathies and non-compressive neuropathies. Muscle denervation recognized on MRI may be a useful sign in the diagnosis of peripheral nerve disorders. ⋯ Chronic denervation produces fatty atrophy of skeletal muscles, resulting in increased muscle signal on T1-weighted images. This review will outline and illustrate the various ways that muscle denervation as seen on MRI may assist in the diagnosis and localization of peripheral nerve disorders.

Case ReportsMultidetector spiral CT venography in the diagnosis of upper extremity deep venous thrombosis.
Upper extremity deep vein thrombosis is a rare thrombotic disorder (1-4% of all DVT) which has the potential for considerable morbidity. We present a case which demonstrates the limitations in diagnostic accuracy of ultrasonography in the diagnosis of upper extremity deep venous thrombosis. Multidetector spiral computed tomography (CT) continues to evolve as a state of the art imaging modality and our case demonstrates the role and value of multidetector spiral CT venography (CTV) in the diagnosis of upper extremity deep venous thrombosis.

Case ReportsDouble superior vena cava with a persistent left superior vena cava: an incidental finding during peripherally inserted central catheter placement.
We describe a case of double superior vena cava with a persistent left-sided superior vena cava discovered at the time of peripherally inserted central catheter (PICC) placement. The diagnosis was suggested by fluoroscopy and confirmed by venography. The relevance of the diagnosis with respect to PICC placement is discussed.

Case ReportsIntramural haematoma of the oesophagus presenting as an unusual complication of endotracheal intubation.
Intramural haematoma of the oesophagus is an uncommon and under-recognized condition. It may mimic other causes of chest pain, haematemesis, or dysphagia, and hence pose a diagnostic challenge. ⋯ Awareness of this uncommon complication is important to allow rapid and timely diagnosis and management. We review the literature, causes and imaging features of this condition.
