We report a case where a 7-year-old girl suffered significant aural bleeding following myringotomy of the tympanic membrane. Investigations by computed tomography scan, carotid angiography, and magnetic resonance angiography showed a lateral aberrant internal carotid artery (LACI) with a little pseudoaneurysm in the middle ear. The anomaly of the internal… (More)
Bone densitometry with DXA (dual energy X-ray absorptiometry) and QCT (quantitative computed tomography) techniques are used for in vivo assessment of bone strength and thereby prediction of fracture risk. However, only few in vitro studies have investigated and compared these techniques' ability to determine vertebral compressive strength. The aim of the… (More)
This study was designed to evaluate age- and gender-related differences in vertebral bone mass, density, and strength by dual-energy X-ray absorptiometry (DXA), quantitative computed tomography (QCT), peripheral QCT (pQCT), ash measurements, and biomechanical testing. The material comprised human lumbar vertebral bodies (L3) from 51 females and 50 males… (More)
Vertebral bone density is evaluated mainly by dual-energy X-ray absorptiometry (DXA) or quantitative computed tomography (QCT). Densitometry is used as an estimator of bone strength and forms the basis for choice of treatment. DXA expresses bone density in grams per square centimeter (area density) and QCT expresses bone density in milligrams per cubic… (More)
PURPOSE To present a new MR classification for pituitary adenomas, a grading system named SIPAP. MATERIAL AND METHODS SIPAP is an acronym for the 5 juxtasellar directions of tumour extension to or penetration into adjacent structures of the sella region, using a 6-figure number for each adenoma. This retrospective study was based on 87 mid-field MR… (More)
In this retrospective study 56 dacryocystographies (DCG) were performed preoperatively in 50 patients with epiphora, due to obstruction in the lacrimal drainage system. We found DCG to be an easy and sufficient examination of patients with uncomplicated epiphora without suspicion of tumour. Tumours in the lacrimal drainage system are rare, and CT-scan or… (More)
Sonographic features of renal candidiasis are nonspecific. Ultrasonically guided aspiration and culture is a quick and easy way to reach the exact diagnosis. We describe one case of parenchymal and one case of pelvic candidiasis diagnosed by percutaneous aspiration.
Two patients with Rathke's cleft cyst with uncommon MR signals, hyperintensity on T1-weighted, and hypointensity on T2-weighted 3-D fast field echo (FFE) imaging are reported. We suggest that this is due to high content of cholesterol or mucopolysaccharide, possibly combined with cell debris from the cyst wall.
Endovascular interventional neuroradiology was introduced less than 20 years ago, and has since then evolved to be an established treatment. Endovascular embolization is particularly well-suited for treatment of patients with intra/extracranial arterio-venous malformations, arteriovenous fistulae and inaccessible arterial aneurysms. Initiated through… (More)
Thirty-seven patients with 42 sacculate intracranial aneurysms of delicate location were treated, or attempted treated, with Guglielmi Detachable Coils (GDC) from July 1994 through December 1995. Intended aneurysm occlusion was not achieved in five patients (five aneurysms) due to unfavourable anatomy. In two additional cases the procedure was interrupted… (More)
