ABSTRACTThe aetiology of pelivi‐ureteric junction (PUJ) obstruction is controversial. We present four patients who had normal or equivocal intravenous pyelograms and non‐obstructive Whitaker tests in whom complete pelvi‐ureteric obstruction was precipitated by more rapid distension of the renal pelvis. We speculate thatin vivophysiological urine flow rates and temporary kinking of PUJ produces a critical increase in pelvic volume and subsequent valvular kinking of the upper ureter, which cannot be usually achieved by maximal urine flow rates alone. Co‐existence of vesico‐ureteric reflux (VUR) may be a contributory factor to critical pelvic distension and tortuous PUJ. Volume related con‐figurational changes of this type are probably a more frequent cause of PUJ obstruction than is generally

摘要:

ABSTRACTSix patients with cystic liver tumours are presented. The definitive diagnosis of such cystic lesions may be difficult and needle aspiration or biopsy or even operation may be necessary. Clinical and biochemical features may be helpful and in five of the six patients presented, the liver function tests were abnormal. In two patients, diagnostic imaging could not distinguish the tumour from a benign cyst. The differential diagnosis of such cystic liver tumours includes simple cyst, polycystic liver disease, hydatid, liver abscess, haematoma and biloma.

ABSTRACTThe extreme distress which possible fetal abnormality induces in expectant parents makes it potentially dangerous to report artefacts seen on antenatal scans, even to dismiss them. A selection of spurious abnormalities is presented, for ultrasound trainees.

摘要:

ABSTRACTIn a study of 100 unselected patients forty years of age or older, routine CT of the thorax demonstrated coronary artery calcification in 41%. Calcification of the left anterior descending was most common, occurring in 34%. For patients 60 years of age and over, clinical evidence of coronary artery disease was 1.7 times more common in those with calcification compared to those without; however, for patients under 60, coronary artery disease was 5.5 times more common in those with calcification than those without. Because of the strong relationship that is known to exist between coronary artery calcification and coronary arteriosclerosis, we believe that the incidental discovery of coronary artery calcification on routine CT of the thorax has significance. All patients under 60 with coronary artery calcification discovered on CT should be investigated for hyperlipidemia if this has not been done, and, if they are not known to have a history of coronary artery disease, they should have a stress test and, if positive, arteriography may be warranted.

摘要:

ABSTRACTA two month old male infant being investigated for nasal obstruction was noted to have the typical facies and radiological changes of craniometaphyseal dysplasia.Investigation of the family detected 9 individuals in 4 generations with radiological evidence of craniometaphyseal dysplasia. Their ages ranged from 2 months to 70 years. Three presented with nasal obstruction, one with facial nerve dysfunction and three had developed deafness in or before their third decade. Two were asymptomatic. One family member, now dead, was known to have had early onset of deafness but had not been examined or X‐rayed.All of the affected individuals were noted to have had the typical facies in childhood. Characteristic radiological findings in the cranium and long bones were present to a varying degree and were most prominent in those presenting in infanc

摘要:

ABSTRACTA patient on long term haemodialysis for analgesic nephropathy, with known teriary hyperparathyroidism developed a rapidly evolving, erosive, non‐infective spondylo‐arthropathy at two vertebral levels. In addition, erosions were noted adjacent to the right sacroiliac joint.Subsequent postmortem material from the affected vertebral levels demonstrated changes consistent with hyperparathryoidism alone and this is suggested as the possible aetiology underlying this recently recognised destructive spondyloarthropa

摘要:

ABSTRACTA five year review of 224 Tc‐99m methylene diphosphonate (MDP) scintiscans of 194 patients with proven nasopharyngeal carcinoma revealed evidence of craniofacial asymmetry in 73.7 per cent. In virtually all instances tracer accumulation corresponded to the side of the primary lesion, cervical node enlargement and or cranial nerve dysfunction.It was concluded that the high frequency of asymmetric ipsilateral MDP accumulation about the face may be attributed to one or all of the following; tumour extension into contiguous structures, localised inflammatory or necrotic changes or even tracer uptake by the tumour itsel
