    Notes: Abstract. We present five cases with gastro (four cases) and intestinal (one case) myogenic tumors with a marked extraluminal growth. In all cases, incidental discovery of an asymptomatic mass prompted further examination. One of three cases with a pedunculated growth mimicked a gallbladder cancer. The mass of a jejunal leiomyoma case changed markedly in location under probe compression. Color Doppler sonography confirmed not only the hypervascular nature of the mass but also feeding and draining vessels.

    Notes: Abstract Background: To reevaluate the advantages and limitations of gray-scale and color Doppler sonography in the diagnosis of splenic artery (Sp-A) aneurysm. Methods: We reviewed the gray-scale and color Doppler sonograms of five cases with Sp-A aneurysm (four patients with portal hypertension and one patient without portal hypertension). Color Doppler sonography was performed in all five patients, and power Doppler sonography was performed in three. Results: Gray-scale sonography failed to detect the aneurysm in four of five cases because of a surrounding splenorenal (Sp-R) shunt in three patients and marked calcification of the aneurysmal wall in one patient. Pulsed Doppler sonography showed a slightly turbulent pulsatile flow along the aneurysmal wall, which immediately led to the diagnosis in four cases, including the three cases with Sp-R shunt. In one case, color Doppler sonography failed to detect the aneurysm because of a markedly calcified aneurysmal wall, although power Doppler sonography could visualize the aneurysm. Conclusions: Gray-scale sonography is not a useful diagnostic tool for Sp-A aneurysm. Clinicians should use color Doppler sonography in the evaluation of the splenic hilus in patients with Sp-R shunt to find a small Sp-A aneurysm. The addition of power Doppler sonography is helpful in visualizing calcified Sp-A aneurysms.

    Hepatic hemangioma with arterioportal shunts (1999)
    Springer

    Keywords: Key words: Liver tumor—Hemangioma—Doppler—Arterioportal shunt.

    Notes: Abstract. Color Doppler sonograms and angiographic findings in 23 hepatic hemangioma patients were compared to clarify how arterioportal shunts influence color Doppler findings of hepatic hemangiomas. The results of our study showed that the presence of arterioportal shunts (six cases) gave rise to large feeding arteries (five cases), multiple intratumoral flows (six cases), and reversal of portal flow within (five cases) or around (four cases) the tumor. These color Doppler findings mimicked hypervascular malignant tumors. Knowledge of such unusual color Doppler findings in hepatic hemangiomas may help in avoiding misinterpretations of color Doppler sonograms. RID=""ID=""〈e5〉Correspondence to:〈/e5〉 H. Naganuma

    Splenic lymphangioma: US and CT diagnosis and clinical manifestations (1999)
    Springer

    Notes: Abstract Background and methods: We tried to determine the role and problems of gray-scale sonography (US), computed tomography (CT), and color Doppler sonography in the diagnosis of splenic lymphangioma on the basis of our experience with seven adult cases with this relatively rare tumor. Results: (1) The whole spleen was replaced by a collection of cysts of different sizes with or without calcifications in six patients. In these patients, color Doppler sonography showed the intrasplenic arteries and veins running along the cyst walls. (2) The enlarged spleen occupied the whole upper abdomen and contained numerous small cysts in one patient. The patient was initially diagnosed as having a pancreatic tumor because of the location, but color Doppler sonography clearly demonstrated two vessels (artery and vein) running parallel from the center of the mass. This characteristic vascular structure led to the determination that the mass was the markedly enlarged spleen. (3) The splenic lesion was isolated in six patients but was associated with mesenteric and pleural lymphangioma in one symptomatic patient. Conclusions: (1) When US shows multiple cysts of different sizes in the spleen, the diagnosis of splenic lymphangioma is not difficult to make with US and CT alone. (2) Color Doppler sonography is a very useful tool to increase diagnostic confidence because it demonstrates the vasculature of the mass. (3) When examining patients with splenic lymphangioma, one should consider the possibility of multiorgan involvement.

    Assessment of resectability of pancreatic carcinoma by color Doppler sonography (1999)

    Notes: Abstract This study was undertaken to evaluate the role of color Doppler sonography in the preoperative assessment of vascular involvement in patients with pancreatic carcinoma. Twenty-six pancreatic carcinomas were investigated with color Doppler sonography and angiography, and the results of these examinations were compared with those of surgical findings. Color Doppler sonography was more sensitive than angiography in depicting vascular involvement of carcinoma. Thus, it seems rational to perform a preoperative assessment in suspected pancreatic carcinoma patients initially with color Doppler sonography to improve patient management.

    Notes: Abstract. Primary tumours of the greater omentum are very rare. Ultrasound allows the detection and characterization of such lesions, but determination of their precise anatomical location is usually difficult by US. Computed tomography determines the omental origin of the tumour. Thus,when US reveals an abdominal tumour of unknown origin, the possibility of an omental tumour, although rare, must be kept in mind and CT should be performed.

    Notes: Abstract. Lobar atrophy of the liver due to causes other than liver tumor or liver cirrhosis is a relatively rare pathological condition, and there are only a few reports in the literature. We report six such cases and try to evaluate the relationship between lobar atrophy and portal flow disturbance. The patients could be divided into two groups according to the site of the atrophy: those with atrophy of the left lobe (two cases) and those with atrophy of the right lobe (four cases). The two cases with atrophy of the right lobe had hepatholithiasis in the involved segments, but the cause was not determined in the remaining four cases. In all six cases, portal flow disturbance was noted, including invisibility of the portal vein in four cases, narrowing in one case, and portal thrombus in one case. Collateral circulation was not recognized in any of our cases. Of interest is the mode of lobar atrophy. Atrophy of the right lobe was always associated with marked enlargement of the left lobe, but that of the left lobe did not induce an enlargement of the right lobe.

    Notes: Abstract. Background: The aim of this study was to reevaluate the causes and sites of intrahepatic venous collaterals and to determine the role of color Doppler sonography in the diagnosis of this relatively rare vascular abnormality. Methods: Real-time color Doppler sonography was used to study 21 patients with intrahepatic venous collaterals. The cause, distribution, and clinical manifestations of collaterals were determined, and Doppler waveforms obtained from the collaterals were also analyzed. Results: First, the causes of intrahepatic venous collaterals were divided roughly into two groups according to the presence or absence of veno-occlusions. The former group included liver tumors (six cases), primary Budd-Chiari syndrome (five cases), and metastatic adrenal tumors invading the inferior vena cava (two cases). The latter group consisted of diaphragmatic hernia (three cases), Osler-Weber-Rendu disease (two cases), and congestive liver (one case). The cause was not determined in two cases. Second, venous collaterals were distributed throughout the entire liver in primary Budd-Chiari syndrome but localized in the other cases. Third, Doppler waveforms of the collaterals were divided into two patterns: flat flow and multiphasic flow. Flat flow pattern was seen in patients with veno-occlusive diseases, and multiphasic flow pattern was seen in patients without veno-occlusive disease. Conclusion: The relationship between intrahepatic venous collaterals and veno-occlusive diseases has been emphasized in the literature, but the results of our series showed that they occurred under a wide variety of conditions, even without veno-occlusive diseases, including diaphragmatic hernia and Osler-Weber-Rendu disease. The analysis of the Doppler waveforms of the collaterals was useful in differentiating those due to veno-occlusive diseases and those not.

    Notes: Abstract. Two cases of small bowel (S-B) varices associated with portal hypertension, one with liver cirrhosis and one with portal thrombus, are reported. Detection of S-B varices has been a challenging task and several invasive diagnostic techniques have been used for this purpose. However, in our cases, color Doppler sonography revealed the S-B varices supplied by the superior mesenteric vein and draining to the iliac (one case) or ovarian vein (other case), which helped to establish an early appropriate diagnostic and treatment plan.

    Notes: Abstract We present five cases of chronic hepatic porphyria (CHP) without skin lesions, in whom a multinodular fatty change in the liver was incidentally detected by ultrasound. Discovery prompted further examinations, leading to the diagnosis of CHP. Although relatively rare, the possibility of CHP must be considered when encountering patients with irregular (multinodular) fatty infiltration of the liver of unknown cause. We also discuss the differential diagnosis.
