A prospective analysis of the incidence of paranasal sinus opacification in 100 patients referred for cranial computerized tomography (CT) for non-sinus related problems is described. The findings were correlated with symptomatic assessment. Twenty-seven per cent of asymptomatic patients had sinus opacification. The study illustrates the importance of careful clinical correlation when interpreting CT scans of the paranasal sinuses.
Meningiomas rarely give rise to metastases despite frequent dural invasion. A rare case of symptomatic hypoglycaemia due to extensive liver metastases from an angioblastic meningioma is described along with the use of hepatic arterial chemo-embolization to effect palliation by reduction in tumour bulk.
A 74-year-old man presented with a feeling of heaviness in his right leg on walking. He had fractured his right tibia 50 years previously, sustaining severe neurovascular damage. Subsequently, he had required sympathectomy for trophic ulcer, tenotomies and toe fusion. He needed an orthopaedic boot to compensate for his shortened leg. There was no other relevant history and the patient was otherwise well.
A 50-year-old Caucasian woman presented with sudden-onset lower abdominal pain with associated nausea and vomiting. There was a history of hysterectomy and treated breast cancer. Of note, the patient was a vegetarian and a keen traveller.Plain radiography of the abdomen, blood tests and an ultrasound examination were unremarkable.As the patient was still symptomatic, a contrastenhanced CT of the abdomen was performed after administration of oral contrast (Figure 1). This showed a long tubular intraluminal lesion in the distal small bowel, which was outlined by oral contrast. Segments of this lesion were noted to be air-filled. No other significant abnormality was identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
