Endomyocardial fibroelastosis is a rare disorder marked by characteristic morphological changes of the endocardium. We report a case of endomyocardial fibroelastosis diagnosed by late gadolinium-enhanced CMR and confirmed by endomyocardial biopsy. The patient improved following treatment with imatinib. 相似文献

Eighty-nine cases of proven Toxoplasma gondii fetal infection were studied in order to describe the morphological lesions which could be demonstrated on ultrasound examination; these were present in 32 of the infected cases. Cerebral ventricular dilatation was the most common sign and was generally bilateral and symmetrical. Its evolution was always very rapid over a period of a few days. Other signs observed included intracranial and intrahepatic densities, increased thickness and hyperdensity of the placenta, ascites and rarely pericardial and pleural effusions. Thirteen fetuses demonstrated two or more ultrasound features. Intrauterine growth retardation and microcephaly were not observed. Ultrasonographic assessment of the fetus injected with Toxoplasma gondii is important. It improves the reliability of prenatal diagnosis and is of important prognostic value in cases with severe brain lesions, but is of little value in detecting brain necrosis without ventricular dilatation. 相似文献

We reviewed the ultrasonographic findings in eight patients with 11 lipomatous uterine tumors studied with transabdominal (eight cases) and transvaginal (six cases) techniques. A transvaginal color Doppler study was obtained in five patients. Two patients had more than one nodule (two and three uterine nodules, respectively). All lipomatous tumors had regular margins and were hyperechoic. Transvaginal sonography allowed the identification of one small previously undetected tumor but was not able to image the entire extent of two large lipomatous masses. In one case, it helped to establish the actual uterine origin of an eccentric pelvic mass. Color Doppler sonography showed complete absence of flow in all tumors examined. We believe that lipomatous tumors of the uterus can be diagnosed with a high degree of certainty by ultrasonography if a homogeneously hyperechoic avascular mass can be clearly identified to be of uterine origin. 相似文献

Two new cases of antenatal diagnosis of arachnoid cyst are described. Diagnosis was made at 2.5 and 32 weeks' gestational age. In the first case, a slight increase in the diameter of the anechoic mass was observed in the second trimester. In the second case, ventricular dilatation was present prenatally. Appropriate surgical therapy was initiated at 2 months in the first case and at 8 days in the second and the neurological development of the two children is considered as normal at 18 months of age. Major features of in utero diagnosis, treatment and follow-up are discussed. 相似文献

Three patients with lipoma arborescens of the knee joint were evaluated with high resolution ultrasonography. All patients demonstrated a hyperechoic, frondlike mass in the suprapatellar bursa with a large associated effusion. All had popliteal cyst formation without involvement by the mass. Dynamic compression and manipulation of the suprapatellar effusion demonstrated pliable and flexible nature of mass with bending and waving of the frondlike mass in real time. Comparison with MR imaging demonstrated similar extent, location, and morphology of the mass. The characteristic features of this lesion as well as its distribution in the knee joint can be demonstrated readily by sonography. 相似文献

Luteoma of pregnancy: sonographic findings in two cases. 总被引:2,自引:0,他引:2
Luteoma of pregnancy is a rare nonneoplastic tumor-like mass of the ovary that emerges during pregnancy and regresses spontaneously after delivery. It is usually asymptomatic and is found incidentally during a cesarean section or postpartum tubal ligation. However, luteomas can be hormonally active, with production of androgens resulting in maternal and fetal hirsutism and virilization. Less than 200 cases have been described in the literature, and none in radiologic journals. Recognition of this entity is important so that unnecessary oophorectomy, with concomitant risk to both the patient and the fetus, is avoided. In this report, we describe two cases of luteoma of pregnancy. The first case documents sequential ultrasonographic demonstration of a presumed luteoma of pregnancy in a patient who was seen with hirsutism during a second trimester pregnancy. The luteoma, serum androgen levels, and patient's condition improved after delivery. This case is unique in that although the mass significantly decreased in size post partum, it continued to be visualized 14 months post partum. The second case illustrates the pronounced cystic appearance that these classically described solid lesions can demonstrate because of extensive necrosis. 相似文献

BACKGROUND: Complete fetal heart block (HB) and endocardial fibroelastosis (EFE) are known to be associated with maternal anti-Ro and anti-La antibodies. Complete fetal HB is irreversible. OBJECTIVES: We sought to (1) assess the value of the superior vena cava/ascending aorta Doppler approach in the early detection of abnormal delay in the fetal atrioventricular (AV) time of conduction, before appearance of complete fetal HB; and (2) report the effect of prenatal steroid therapy on EFE, HB, or both. RESULTS: The clinical history, echocardiographic, and Doppler investigations of 3 fetuses and children born to mothers positive for anti-Ro and anti-La antibodies are reported. Two fetuses presented with EFE either isolated (29 weeks) or associated with AV block (25 weeks). In this last case, the superior vena cava/ascending aorta approach allowed the identification of a Luciani-Wenckebach phenomenon. In a third fetus, 2:1 AV block was noted at 23 weeks of gestation. Dexamethasone (4 mg/day) was administered to all 3 patients. Complete regression of the EFE and conduction abnormalities was documented in all cases. CONCLUSION: Early prenatal detection of abnormal delay in fetal AV time conduction is possible with the Doppler superior vena cava/ascending aorta approach. Steroid therapy can cure fetal EFE and AV conduction delays associated with maternal anti-Ro and anti-La antibodies. 相似文献

MURCS association is a rare, lethal and unusual constellation of nonrandom findings that includes mullerian duct aplasia, renal aplasia, and cervicothoracic somite dysplasia.1-3 It has been described in 30 patients by Duncan and coworkers2 in 1979, in which report the authors proposed an embryologic cause for these defects.3 Antenatal ultrasonographic findings included a massive, cystic umbilical cord related to a patent urachus, enlarged bladder, single small kidney, and suspicion of urethral obstruction in a fetus of female phenotype. These findings are rare in a case of MURCS and were all confirmed on pathologic examination. 相似文献

OBJECTIVE: To evaluate the functional prognosis of kidneys affected prenatally by urinomas. METHODS: This was a retrospective review of cases of fetal urinoma reported in the literature, as well as two of our own cases. RESULTS: Twenty-three patients with a prenatal diagnosis of urinoma (five bilateral) were included in the analysis. Postnatal ipsilateral renal function was observed in only six of the 28 renal units (i.e. around 20%). CONCLUSIONS: Although the precise causes of urinomas are still unknown, this review shows that in the event of a fetal urinoma, the probability of a non-functional dysplastic ipsilateral kidney lies at around 80%. In-utero puncture only appears to be justified in cases where fluid accumulation has mass effects on adjacent major structures. 相似文献
