We report a case of rectal teratoma coexistent with an ovarian teratoma. To our knowledge, this is the first radiologic report of rectal teratoma. Computed tomography (CT) showed a sharply demarcated cystic and fatty mass with amorphous calcification in the rectum. A double-contrast barium study showed a well-defined intraluminal rectal mass without mucosal destruction. Imaging findings of rectal teratoma allow for correct preoperative diagnosis. CT was helpful in differentiating rectal teratoma from other rectal lesions.

A case of a woman aged 42 years old with abdomen pain under the navel and bilateral pelvis tumors indentified by CT scanner as post-peritoneal tumors and AFP level increased was treated at Viet Duc hospital with the diagnosis of embryonary carcinoma based on a mature malignant teratoma. Some aspects of the diagnosis and treatment of post-peritoneal teratoma with embryonary carcinoma were received. Authors concluded that up to now in adults for post peritoneal tumor under the group of germ cell tumors, the treatment of choice is a surgery of through removal of the tumor, then the formula of BEP, PEL or VAC chemiotherapy will be carried.

A case of teratoma in a male patient aged 53 years old at the liver left lobe, hospitalized 25 November 2002 at The Hospital 198 was persented. It was a special form of mature teratoma of dermoid cyst. Macroscopically, it was a cyst of large size with thick fibroid shell, containing fat fluid, caseinous matter, hair, cartilaginous bone and even 3 molar teeth. Microscopically, it was a lining of cells of keratinoid epithelial scale tissue in the wall. Under the epithelial cover there was a conjunctive tissue inserted by sebacenous tissues, sweat gland tissues, hair alveoli and vessels with thick fibrous wall.

Ultrasongraphy is a safe, noninvasive examination which should be the first procedure in the workup of apatient with a definite or suspected pelvic masses. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass canbe used to subcategorized these masses into a more useful differential diagnosis. The results are as follows; 1.The most characteristic finding of uterine myoma was midly to mederately echogenic uterine enlargement (90.7%)with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterincontents(93%). 3. The most frequent finding of cystic teratoma was cystic mass with echogenic foci(48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancywere adnexal mass(comlex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid incul-de-sac, deveiation of uterus by adnexal mass, and psuedointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false-negative in 7.4%.

Gliomatosis peritonei, the implantation of neuroglial tissue upon the peritoneal surface, is a rare event most often associated with solid or immature teratoma of the ovary in young girls. The majority of cases occur in association with teratomas containing immature element. However malignant transformation of the glial tissue has been reported. Here we experienced a case of mature glial implants presenting in an 27-year-old female, 10 years after initial diagnosis and removal of an ovarian immature teratoma, and report this case with brief review of literatures.

Massive congenital intracranial teratoma is a very rare. We report the prenatal ultrasonographic diagnosis of a massive intracranial teratoma in a 323 weeks pregnancy associated with severe hydrocephalus and polyhydroamnios. Prenatal ultrasound revealed a large heterogeneous echoic mass which almost replaced the normal intracranial structure. By transabdominal and transvaginal cephalocentesis, fetus was terminated vaginally and safely. We have reviewed with attention to clinical presentation, sonographic characteristics and associated findings and man-agement and prognosis of massive congenital intracranial teratoma.

A case of retroperitoneal teratoma, found in a ten month old female infant was reported. Twenty four hours after the direct retroperitoneal air insufflation, a retrograde pyelography was performed using B.B. 16F. cytoscope. These two studies were essential to make preoperative diagnosis. Review of retroperitoneal tumor was also added.

The coronal sectional image of computerized tomography creates an image that is similar to an excretory urogram. It also provides more clearly delineated renal image and image of adjacent organs than an excretory urogram. Further more, the number, extent, and content of renal mats lesions used to discriminate density difference can be determined with relatively great accuracy. This image of computerized tomography is useful to understand and make a diagnosis of renal disease. Coronal sectional image of computerized tomography is more informative in evaluation of retroperitoneum space than conventional radiography. Recently we observed several cases of renal disease-renal cell ca, simple renal cyst, angiomyolipoma, retroperitoneal teratoma, pheochromocytoma, hydronephrosis which could be detected with coronal sectional image of computerized tomography.

The Currarino triad is a unique complex of congenital caudal anormalies including anorectal malformation, sacral bony abnormality, and presacral mass. Histologically the presacral mass has been identified as a meningocele, teratoma, enteric duplication or a combination of this. A Case of female infant with this triad was presented and was successfully treated by surgery. The presacral mass was a lipomyelomeningocele. The clinical features, unique radiologic findings, and importance of a correct diagnosis of currarino triad were reviewed.

n in 93 of the 112 tumors (83.0%), with pure cystic masses (types I-III) accounted for the remaining 19 tumors (17.1 %). Of the 112 tumors, 68 (67.1%) showed posterior sonic shadowing which was demonstrated only in the hyperechoic area of types IV-VI. CONCLUSION: Any adnexal masses representing a hyperechoic area within a cyst, solid and cystic tumors containing hyperechogenicity or diffusely hyperechoic mass, especially when accompanied by posterior sonic shadowing, should be suspected as indicative of mature cystic teratoma.
