A variety of neoplasms can develop in each tetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplosms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings.

Lymphangioma of the large bowel is a rare benign tumor which is composed of numerous small or large thin-walled lymphatie spaces contained fibrous tissue, smooth muscle and aggregates of lymphoid tissue. Lymphangioma never demonstrated any potential for malignant degeneration. There are three types; l. simple capillary lymphangioma, 2 cavernous lymphangioma and 3 cystic lymphangioma. Endoscopically, lymphangioma appears as a compressible smooth, round, or oval submucosal tumor covered with pale intact mucosa. The surfaces is smooth and the superficial color is the same as the surrouding mucosa or slightly more yellowish. There are change of dimension and shape during propagation of the peristaltic wave and on compression. Recently, authors experienced 4 cases of lymphangioma of large intestine which has been revealed by typical colonoscopic findings and/or endoscopic ultrasound, and confirmed by surgical resection and colonscopic snare polypectomy. 3 of 4 cases show cystic lymphangioma and one case shows carvenous lymphangio~rna. We report these cases with review of literatures.

A lymphangioma is a benign tumor and predisposed to the neck and the axillary region. A lymphangioma of the kidney is a very rare and seen as multilocular cysts in imaging studies, and are difficult to differentiate from other malignant cystic diseases. A 53 year-old man was referred for known right renal cysts. Abdominal ultrasonography and computed tomography showed a 4.0x3.6cm multiloculated cystic mass in the right upper pole of the kidney and 2.3cm sized simple cyst in the ipsilateral mid pole. Malignant cystic diseases could not be excluded from the radiological studies. He underwent a radical nephrectomy. Gross examinations revealed a multilocular cyst protruding from the renal parenchyme. The multilocular cyst was located in the upper pole of the kidney, with another simple cyst in the mid pole. Microscopic examinations showed that attenuated flat to cuboidal cells paved the multilocular cyst, but no nephron was seen in the cystic wall. A distinct thick fibromuscular bundle represented a large lymphatic channel. These findings were compatible with a lymphangioma.

PURPOSE: To evaluate the efficacy of OK-432 solution for sclerotheraphy of cystic lesions of the head and neck. MATERIALS AND METHODS: Nineteen cystic lesions comprising ten plunging ranulas, three simple ranulas, three cystic lymphangiomas, one first branchial cleft cyst and two unknown supraclavicular cysts considered to be lymphangiomas were treated by sucking out as much liquid content as possible and then injecting the same volume of OK-432 solution under ultrasound guidance. Patients were followed up clinically and radiologically. RESULTS: Follow-up sonography or CT performed after a mean interval of nine months showed total or near-total shrinkage of four plunging ranulas. However, six such lesions recurred in spite of more than one (mean, two) sclerotherapy sessions. In cases involving two simple ranulas at the floor of the mouth, failure resulted from extracystic leakage of OK-432 solution via the puncture site. Two unilocular cystic lymphangiomas completely regressed during the follow-up period (mean, seven months), but the multilocular type showed a 65% volume reduction after 12 months. A first branchial cleft cyst was markedly reduced in size, with only a small cystic portion remaining after eight months, follow-up. Two supraclavicular cysts with straw-color fluid did not respond to sclerotherapy. CONCLUSION: OK-432 sclerotherapy of macrocystic lymphangiomas is an effective and promising alternative to surgery. For other cysts, however, including plunging ranula, efficacy varied, and 64% of such lesions recurred.

Fetal cystic hygroma is a rare congenital malformation of the lymphatic system appearing as a single or multiloculated fluid-filled cavity, most often in the neck. A case of fetal nuchal cystic hygroma was diagnosed by Ultrasonography at 22 weeks of gestation and the diagnosis was confirmed at autopsy. We present the case with a brief review of literature.

The sonographic features of 23 lymphangiomas (19 pediatric patients) were compared with the pathologic findings. Nineteen lymphangiomas appesred as unicameral (n=2) and multiloculated (n=7) cystic masses. Remaining lesions were inhomogeneously echogenic mass with small cystic portions (n=3) and a mixed pattern (n=1). Fourteen of the multiloculated tumors had thin septa and 6 had solid echogenic foci. The fluid within the majority of the cyst was anechoic in 8 cases and echogenic in 11 cases. Correlation of the sonographic features with the pathologic findings demonstrated that the cystic spaces corresponded to the dilated lymphatic spaces lined with endothelium, separated by septa. Echogenic fluid represented hemorrhage. The echogenic component corres ponded to clusters of very smaller dilated lymphatic channels, thick fibro-fatty septa, or blood clot. The author's experience suggests that the most characteristic sonographic appearance of lymphangioma is a multiloculated cysti mass with thin septa, reflecting the preponderance of fluid-filled spaces. An atypical appearance usually reflects the presence of blood or dominancy of cavernous type. The information obtained with US imaging can help in providing a preoperative diagnosis and in planning surgical resection.

Intrascrotal lymphangioma is a rare benign lesion of uncertain etiology. A 2-year-old male and a 3-year-old male presented with painful swelling of the right scrotum. After sonographic examination of scrotums, both cases were explored and found to have cystic scrotal masses separated from testes and epididymies. Histopathologic study of the resected specimens confirmed intrascrotal lymphangiomas.

Fetal cystic hygromas are congenital malformations of the lymphatic system manifested as single or multiloculated fluid-filled cavities in the neck region. Cystic hygroma is characterized by cystic appearance of posterior or lateral portion of the neck. A case of cystic hygroma, diagnosed antenatally by ultrasound at the 11(+1)th week of pregnancy and confirmed by autopsy, is presented with a brief review of literatures.

Cystic lesions of the stomach are rare and usually detected incidentally during surgery or autopsy. Amongseven cases of cystic masses, duplication cysts accounted for four, retension cysts of ectopic pancreas for two,and cystic lymphangioma remaining one. In the upper gastrointestinal series, all were submucosally, whileendoscopic ultrasonography showed that the location of cystic masses was also submucosal. Except for two cases ofduplication cyst and cystic lymphangioma which were thin-walled, lesions were well-defined and showed lowattenuation. In addition, abdominal CT scanning showed two cases of retension cyst of ectopic pancreas.
