Sonographic findings in a case of scrotal lymphangioma

The scrotum is an extremely rare site for lymphangioma. We report the case of a scrotal lymphangioma in a 20‐year‐old male patient who developed painless scrotal swelling. Typical sonography and MRI findings are shown. Surgical excision and histopathology confirmed the diagnosis. © 2013 Wiley Periodicals, Inc. J Clin Ultrasound 42:234–236, 2014     

Sonographic findings of prenatal torsion of ovarian lymphangioma

Ovarian cysts are primarily of follicular origin, and ovarian lymphangioma is an extremely rare lesion. Most ovarian cysts demonstrated on prenatal sonograms are asymptomatic and resolve antenatally. We report a case of ovarian torsion in utero secondary to an ovarian lymphangioma in which sonographic examination revealed a changing pattern of the cystic ovarian mass from an anechoic to echogenic appearance.     

A pitfall in diagnosing fetal abdominal lymphangioma: A report of two cases

Typical ultrasound findings of fetal abdominal lymphangioma include thick-walled, multiseptated anechoic masses. Although a majority of cases can be suspected promptly by ultrasound examination, the two cases presented herein did not meet the standard criteria and were misleading. Both cases involved unilocular cysts without clear septations, but in retrospect were atypical findings of fetal abdominal lymphangioma. A few reports of misleading cases have been described previously; however, the precise characteristics have not been reported in detail. Therefore, in this case report, we focused predominantly upon the difficulties encountered in the prenatal diagnosis of abdominal lymphangioma based on ultrasound morphology alone.     

Sonographic findings in a case of scrotal lymphangioma in a 68‐year‐old male

Lymphangiomas are benign tumors resulting from a congenital lymphatic malformation in infant and children. Most common sites are head, neck and axilla, and scrotal lymphangioma is very rare. Lymphangiomas are classified as capillary, cavernous, and cystic type and cystic type is most common. Complete surgical excision is definitive treatment and incomplete excision leads to local recurrence. We report a case of scrotal lymphangioma in 68‐year‐old male patient. Gray‐scale sonography revealed multiseptated, hypoechoic mass abutting the upper pole of the normal right testis. Color Doppler sonography showed no remarkable blood flow in the mass. MRI demonstrated multispetated extratesticular and extraepididymal mass in the right scrotum. Surgical excision was performed and the histopathologic diagnosis was a cystic lymphangioma. In conclusion when multiseptated cystic scrotal mass was discovered in an elderly patient, scrotal lymphangioma should be included in differential diagnosis. © 2009 Wiley Periodicals, Inc.

Sonographic findings in two cases of complicated pregnancy in women previously treated with endometrial ablation

When medical therapy fails for menorrhagia in a premenopausal woman, minimally invasive endometrial ablation can be used as a conservative management alternative to hysterectomy. Endometrial ablation alone is not considered effective contraception, and women of reproductive age can become pregnant after ablative therapy. We now present two cases of pregnancy after endometrial ablation and associated imaging where both cases required cesarean hysterectomy due to post partumhemorrhage. Pregnancy after endometrial ablation incurs increased morbidity and diagnostic dilemmas. © 2012 Wiley Periodicals, Inc. J Clin Ultrasound 41 :566–569, 2013.     

超声诊断腹腔囊性淋巴管瘤2例

病例例1,男,38岁.因左下腹疼痛5年加重3天入院.查体:左下腹压痛明显;超声检查:左中下腹部见一7.9cm×7.6cm×6.0cm的囊性包块(图1).边界清楚,囊壁薄,光滑,内见细小点状回声,随体位移动.     

Anterior mediastinal lymphangioma: Pre‐ and postnatal sonographic findings

Anterior mediastinal lymphangiomas are very rare in utero with only a few cases reported in literature. We present a case of anterior mediastinal lymphangioma that was diagnosed on prenatal sonography (US) at 22 weeks' gestation. It appeared as a well‐defined, multi‐septated anechoic mass, in the anterior mediastinum between the heart base and right chest wall. There was no solid component and no internal flow on color Doppler US. The pre‐ and postnatal US findings are correlated with prenatal MRI and postnatal CT findings. © 2012 Wiley Periodicals, Inc.

Color Doppler findings in Castleman's disease of the mesentery

Castleman's disease is a relatively rare lymphoproliferative disease. We report an asymptomatic case of Castleman's disease isolated to the mesentery and detected incidentally by sonography. In this case, color Doppler sonography demonstrated an artery penetrating the mass's hilum, suggesting a lymphatic origin of the lesion, as well as fine accessory peripheral arteries, suggesting malignancy. To our knowledge, there has been no previous report of detailed color Doppler findings in Castleman's disease. © 1998 John Wiley & Sons, Inc. J Clin Ultrasound 26:474–478, 1998.     

Sonographic findings of mesenteric panniculitis: correlation with CT and literature review

PURPOSE: To evaluate the sonographic findings of mesenteric panniculitis (MP) and correlate them with CT findings. METHODS: We retrospectively evaluated the clinical, CT, and sonographic findings in 26 cases of MP in our hospital between January 1997 and July 2003. We also reviewed the sonographic features of MP previously described in the literature. RESULTS: The sonographic findings were well correlated to CT in 24 of 26 patients (92%). In these 24 cases, abdominal sonographic examination revealed a hyperechogenic, well-defined fatty mass (corresponding to the pseudocapsule CT sign) in the root of the mesentery, displacing the bowel loops. We found a clear interface between MP and normal intra abdominal fat. Examination with color Doppler sonography revealed the nondeviated mesenteric vessels within the mass. The persence of MP improved sonographic transmission in 9 obese patients and enabled the retroperitoneal vessels to be clearly visualized. Sonography was unable to demonstrate the preservation of the fat nearest the mesenteric vessels corresponding to the "fatty halo" sign on CT. CONCLUSIONS: Sonography is useful in the diagnostic workup for MP. The characteristic sonographic features of MP (well-defined mass, homogeneous hyperechogenicity of the mass, nondeviated vessels within the mass, and displaced bowel loops) correlate well with CT findings.     

Sonographic findings in scrotal brucellosis

Six patients with scrotal brucellosis were ultrasonically examined. All cases were of acute onset. Concomitant involvement of testes and epididymes were noted in all cases except one in which the epididymis was spared. Abnormal sonographic findings consisted of enlargement of the testes and epididymes, nonhomogenous hypoechoic diffuse, or focal echo patterns in all cases and a hydrocele in one case.     

Sonographic findings of hibernoma. A report of two cases

We present 2 cases of hibernoma, a rare lipomatous tumor arising from brown fat tissue. In each case, a hyperechoic mass in comparison to surrounding musculature combined with elevated vascularization was highly suggestive of a liposarcoma. As a rule, malignancy cannot be excluded safely by imaging modalities, and a preoperative biopsy should be performed. Although rare, hibernomas should be considered in the differential diagnosis of lipomatous soft-tissue tumors.     

Sonographic findings in Richter's hernia

Richter's hernia can present as a diagnostic challenge because of its usually small size and eccentric bowel wall involvement with limited luminal compromise. This article describes a case of Richter's hernia in the femoral canal and illustrates its sonographic features.     

Intra-abdominal lymphangioma in a newborn

We report the case of a male newborn infant with an intra-abdominal cavernous lymphangioma that produced acute abdominal symptoms. Sonography showed a cystic mass with thin septations, which caused intestinal obstruction and stenosis of the iliac artery. The histologic findings after surgical resection reflected the sonographic appearance of the mass. The differential diagnosis of cystic abdominal lesions is discussed. Sonography is the preferred method of diagnosis. © 1998 John Wiley & Sons, Inc. J Clin Ultrasound 26:320–322, 1998.     

完整结肠系膜切除在老年结肠癌患者中的应用分析

目的探讨完整结肠系膜切除(CEM)治疗老年结肠癌的临床疗效。方法选取2011年2月至2013年2月行CEM老年结肠癌患者43例的病史资料进行回顾性分析,同时选取同一手术组2011年2月以前行传统结肠癌根治术治疗的老年结肠癌患者30例作为对照组,对比分析两组患者的各项临床指标以及临床疗效。结果观察组淋巴结清扫数量(22.5±3.1)枚,显著多于对照组(19.3±3.0)枚,差异有统计学意义(P0.05);观察组Ⅲ期淋巴结清扫数量显著多于对照组,差异有统计学意义(P0.05);两组手术时间、住院时间,术后排气、排便时间,术后并发症发生情况比较无显著差异(P0.05);但观察组术中出血量显著小于对照组(P0.05)。结论老年结肠癌病人应用CEM可减少术中出血量,提高淋巴结清扫率,且不增加手术风险及术后并发症的发生率。     

Prenatal diagnosis of fetal chest lymphangioma.

OBJECTIVE: Prenatally diagnosed cystic nuchal hygroma is often associated with chromosomal anomalies and hydrops fetalis. Chest lymphangioma diagnosed later in gestation appears to be a completely different disease, with a low incidence of chromosomal and structural anomalies. METHODS: Two chest cavernous lymphangiomas of the fetus are presented. The sonographic images, chromosomal analyses, and macroscopic and microscopic evaluations are described. RESULTS: Fetal chest cavernous lymphangiomas were identified at 15 and 22 weeks' gestation. In the first case, the couple decided to interrupt gestation. In the second case, prenatal sonography showed a multilocular, cystic lymphangioma external to the chest wall with no flow on Doppler sonography. Follow-up sonography revealed normal fetal growth and slow enlargement of the cystic mass surrounding the left chest cavity. The neonate was delivered without complications and was treated surgically. CONCLUSIONS: The chest lymphangioma appears to be a lesion usually not associated with other congenital abnormalities. The prenatal diagnosis of chest wall lymphangioma is relatively easy sonographically, and the treatment of choice is surgical excision. The outcome is relatively favorable, with a low incidence of chromosomal and structural anomalies.     

完整结肠系膜切除治疗结肠癌的疗效分析

目的探讨完整结肠系膜切除(CME)在结肠癌治疗中的价值。方法将2012年12月至2013年12月采用CME治疗的结肠癌患者35例作为观察组,将2011年3月至2012年4月采用传统根治术治疗的结肠癌患者35例作为对照组。评估两组手术质量,对比淋巴结清扫数量、术中平均出血量、平均手术时间以及术后排气时间,观察两组术后感染、吻合口瘘等并发症以及复发情况。结果观察组手术质量C级占100%,明显高于对照组(51.43%);观察组淋巴结平均清扫数目为23.5±4.6枚,高于对照组(18.4±2.3枚),观察组手术时间与对照组无显著差异,但出血量较对照组少,术后排气较对照组早,观察组并发症发生率为8.57%,明显低于对照组(20.0%),且复发率(5.71%)也明显低于对照组(17.14%)。组间比较差异均有统计学意义(P0.05)。结论 CME治疗结肠癌临床疗效明显,较传统结肠癌根治术效果好,且并发症发生率和复发率低。
