[INTRODUCTION - Hereditary angioneurotic oedema (HANO) is a rare cause of ascites. As acute abdominal attacks of the disease can mimic surgical emergencies, the prompt and accurate diagnosis is essential. This study was undertaken to evaluate the usefulness of abdominal ultrasound examinations in the differential diagnosis. PATIENTS AND METHODS - Seventy patients with HANO were followed up for almost a decade. All patients presenting with an acute oedematous attack underwent abdominal ultrasound, which was then repeated 24 and 48 hours after appropriate therapy. RESULTS - 22 patients with acute oedematous attacks with abdominal complaints severe enough to justify hospital admission occurred in the study population. Abdominal ultrasound performed during the attack showed oedematous thickening of the intestinal wall in 80 per cent of cases and invariably demonstrated the presence of free peritoneal fluid in all patients. Rapid symptomatic relief achieved by treatment was accompanied by the significant regression of ultrasound abnormalities. CONCLUSIONS - Demonstration of transitory ascites by abdominal ultrasound is a clue to the diagnosis of an acute abdominal attack of HANO. The possibility of HANO should always be considered whenever unexplained abdominal pain returns with or without ascites.]

[I measured the length, width and height of the skull’s hole on standard two-direction radiographs. From these data the volume of the skull's hole can be calculated with high accuracy. I used for calculation the modified formula of sonographic determination of prostate size. Using this measurement method in 1.000 adults (500 male and 500 female) the average skull's hole volume was 1.492 cubic centimetres. In 100 children of 6-7 years (50 boys and 50 girls) average skull's hole volume was 1.423 cubic centimetres.]

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

Chronic cerebrospinal venous insufficiency - disease or misdiagnosis?

PÁNCZÉL Gyula, SZIKORA István, BERENTEI Zsolt, GUBUCZ István, MAROSFŐI Miklós, KOVÁCS Krisztina, RÓZSA Anikó, RÓZSA Csilla

Background and purpose - Former studies reported internal jugular vein stenosis in patients with multiple sclerosis. We aimed to evaluate if these venous stenoses were real and cerebral venous outflow of patients with multiple sclerosis differed from that of normal controls. Methods - 20 controls were prospectively investigated by angiography and duplex ultrasound. Seven patients with multiple sclerosis underwent angiography in other centers; we reviewed these registrations and performed venous ultrasound examinations. Results - Angiography displayed >50% stenosis of internal jugular vein in 19 controls (69±17% on the right and 73±13% on the left side) and <50% stenosis in 1 control (43.5% and 44.6%). All 7 patients had at least one-sided stenosis. The mean degree of stenosis was 63±16% on the right and 67±13% on the left side. There was no significant difference in the degree of stenosis between patients and controls. However, these “stenoses” disappeared if the contrast agent was injected at a catheter position below the orifice of the subclavian vein during venography. The venous flow volume was also similar between groups: 479.7±214.1 and 509.8±212.0 ml/min (right and left side) in the patients and 461.3±224.3 and 513.6±352.2 ml/min in the control group; p=0.85 and 0.98 (right and left). Color and power duplex imaging also revealed normal blood flow of the internal jugular vein in all patients and controls. Conclusion - The cerebral venous status of patients with multiple sclerosis and controls were similar. The angiographic “stenoses” were virtual, caused by the contrast dilution effect of the non-contrast blood stream of the subclavian vein.

[Ultrasound of the acute pediatric scrotum]

COLEY D. Brian

[Proper evaluation of the acute scrotum, like any condition, starts with a history and physical examination by an experienced clinician. Often this is all that is needed to arrive at an accurate diagnosis, which then allows prompt and appropriate treatment. However, the true nature of the underlying disease producing scrotal pain is not always clear, and the consequences of error (testicular loss) are undesirable. Ultrasound is the single most useful imaging tool for imaging the scrotum. While nuclear medicine studies can help assess blood flow, the combination of anatomic detail provided by modern ultrasound equipment and the ability to assess blood flow and perfusion with color Doppler makes ultrasound invaluable. Properly performed and interpreted, ultrasound provides very high sensitivity and specificity for acute scrotal conditions. Understanding of the conditions that produce acute scrotal pain in children will improve one’s diagnostic abilities. The most important diagnosis to consider is testicular torsion, since untreated this will result in testicular death. While testicular torsion can occur at any age, it is most common in the perinatal and peripubertal age groups. Torsion of a testicular appendage is a frequent cause of scrotal pain in prepubertal males. The sonographic findings can mimic epididymitis, but diligent and focused sonographic examination can make the diagnosis. Epididymitis typically affects postpubertal males, but can be seen in younger patients with functional or anatomic urinary tract anomalies. Sonographic evaluation of the post-traumatic painful scrotum can help to differentiate injuries that can be managed conservatively and those that require surgery. Less common causes of scrotal pain include hernias and hydroceles, vasculitis, and idiopathic edema. Understanding the characteristic sonographic features of these conditions allows the examining physician to make more accurate and confident diagnoses. It is hoped that this review article will help to promote this understanding.]

[The role of MRI in the diagnosis of tumours]

GŐDÉNY Mária

[Imaging is important in the evaluation of tumour detection, staging to determine the response to therapy, to follow the patient to find an early recurrent tumour. The ability to assess cancer spread has been revolutionized by advances of digital imaging modalities, such as digital ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). MRI is the method of choice for detecting and evaluating brain, spine, head and neck and musculoskeletal tumours, but it is complementary in the investigation of the thorax. US and CT remains the primary test for imaging the abdomen, while MRI plays a subsidiary role as a problem solving technique. In the evaluation of focal liver disease numerous prior reports have documented a superior performance of MRI compared to CT and US in the detection of primary and metastatic liver tumours. MRI is gaining more and more importance in imaging of the pelvis. Breast MRI is increasingly used as an adjunct to conventional imaging modalities. Several recent developments in MRI have altered the role of this imaging, and it is often the preferred choice among diagnostic tools for the detection and characterization of tumour cases.]

[The malignancy associated fl uids like pleural effusion, ascites and pericardiac fl uid are a common problems in patients with cancer. Despite the existence of typical types of cancer for these fl uid accumulations, nearly all types of cancer can cause malignancy associated fl uids. The presentation of these fl uids is generally a sign for disease progression, and forecast a poor prognosis. The prognostic factors include the type of cancer, the response to antitumorous therapy and the general condition of the patient, which include age, ECOG status and so on. In most of the cases, the treatment of these fl uid accumulations is supposed to decrease the symptoms, and guarantee an acceptable quality of life, consequently the treatment has a palliative intent. Indeed, there are some exceptions such as cardiac tamponade. From the large scale of available treatments, we have to choose upon careful risk analysis.]
