 My name is Meghna Shaini. I'm a second year post graduate. I'm from Usmania Medical College. My topic is rule of imaging in pediatric embryology. First of all, I would like to thank Indian radiology for giving me this opportunity. I'm going to do the introduction part. The embryonal tumors constitute a major part in the pediatric group of population. Though they can occur at any age, they'll usually occur within five years of age, according to the literature. The incidence is very, regarding Asian gender is a very important thing, arriving after diagnosis. And the radiology plays in characterizing these tumors, however, it fails in arriving at a specific diagnosis. My aim of the study is to include the embryonic embryonal-oriented tumors as a differential in pediatric age group of population. And to mention entities where the embryonal tumors have been diagnosed as non-embryonal tumors, and some entities where their diagnosis is embryonal tumors, and when the embryonal tumors or diagnosis is even a non-neoplastic etiology. And what is the incidence of embryonal tumor in relation to the gender at age? 15 children were included in this study under the age of 14 years for about one year. All biopsy proven cases of the embryonal tumor is irrespective of the system it is involving. And the children with non-embryonal tumors and the wrongly diagnosed embryonal tumors from radiology have been excluded. And there are some images where the image quality has been severely compromised due to the motion artifacts. They're also excluded and the study has been excluded. And 15 children were advised to play in alfalfa city using canon success life CD. So the my results are, so the study population is 50 under the age of 14 study period is one year. Out of the 50 children who are diagnosed with embryonal tumors 38 or presented with abdominal masses 10% with the brain masses and 2% with the thoracic masses. So coming to the, in our, under the abdominal tumors we got 20 cases of fins, 8 cases, out of the 20 cases of the fins, 17 children were male and 3 children were female. And we got 8 cases of the neuroblastoma where 7 were male and 1 was female. Under the 5 cases of the retroperitonal diuretoma where we got all females, we have a one case of mesenchymal hematoma of the liver in a female. There are 3 cases of the hepatoblastoma where all, which was presented in all males and one case of embryonal raptomyosarcoma of the CBD, we saw that case in a male. And coming to the brain tumors, we came across medulla blastoma and the peanut. We saw 8 cases of medulla blastoma in males, I mean, all the children were males, and we saw 2 cases of the peanut tumors in all, where all the children were males. We got 2 cases of the pleuropernal blastoma under the chest tumors, we saw all 2 cases in the males. So coming to the, how the embryonal tumors have been initially diagnosed as the mesenchymal hematoma, the children actually came with abdominal distension when the ultrasound was scanned, there's a multi-located lesion in the liver, which we surely thought it was high resist, and a likely abscess was given as the report. But when we saw, when we do, when we did a CECT, it was, there was some enhancing components of the lesion, then we thought it was a tumor, the biopsy can have to be mesenchymal hematoma. And there are 2 solid astrocytoma, there is no mural nodule, which of, there is no cystic component, that's why we thought it was a medulla blastoma, but it was turned up to be astrocytoma, which is very solid, which didn't get any cystic component. One peanut was diagnosed as ependymoma, those superventricular ependymoma is very rare because of the, but the chunky, large and chunky calcification nature was actually gave us a diagnostic diagnosis. And embryonal blastoma, actually the child was a fire-age male, and he has a cytosine, the abdomen, and there is some solid components of the hyalum in the ultrasound, thought it was some necrotic lymph nodes, we did CT, then also we thought it was necrotic lymph nodes, but the biopsy, I'm sorry, not biopsy, the sciatic fluid analysis, and then seeping at everything came out, came negative for the TB, then we did the biopsy of the hyalurusion, we came up with the as embryonal raptomyosarcoma. Actually, that is, we didn't face any type of CTalamo and hyaluryses, I mean, the blastoma. So when coming to the incidence of the tumors and the guptamen tumors, wills and neuroblastoma constitutes a majority, and the brain tumors, medulla blastoma constitutes the majority, and we had got, we didn't get any of cases of the chest tumors to comment about it, but this actually, this incidence actually goes with the literature. I said, and the median age of the presentation is wills around 4.5 neuroblastoma at 7.5, and teratoma at 3.5, mesenchymal hematoma below the one year of age, and hepatoblastoma at 2 years, amylo raptomyosarcoma, we got it, 5 years of age, medulla blastoma at 4, and peanut at 2.5 years of age, and pulmonary blastoma at 3 years. Gender distribution except for the retropytonal teratoma and mesenchymal hematoma, everyone got a male preponderance, but the thing is the retropytonal teratoma and mesenchymal hematoma are more senior females, that can be because we didn't, we didn't have enough cases to comment, to actually comment about the gender distribution, but in our study we saw them in females. Come on to the some of the examples, this is an active CT section showing a large heterogeneously enhancing lesion in the right front of temporal region, and it is showing a lot of calcifications, this large tumor have been having a mass effect on the ventricles, that's why there is a hypo-substume hypo-surplus and there is also a mass effect in the form of a midline shift. So this is actually usually we thought it is a supertentorial epandema because of the large and chunky calcification ratio of the lesion. Next is retropytonal teratoma, here there is an heterogeneously hypodensation in the retropytonium, with the fatty areas and the areas of the calcifications we are seeing here, and it is actually displaced in the kidney downwards, where it can be retropytonal teratoma. Next is mesenchymal hematoma of the liver, here we are seeing a very large hypodense lesion when compared to the liver, and there is a cystic areas within it, actually in the contrast there is actually enhancement of the solid part of the lesion, but they were not shown here because of the gross motion artifacts. And we saw this case in a female. This is a vinsch tumor, this is an heterogeneously enhancing lesion we are seeing, which is actually cross in the midline, and there are some areas of the non-enhancement is there, and the organ embedded sign of the left kidney is positive. I think there is a large level of retropytonal mass lesion in the left adenose region, and it is actually showing the calcification with areas of the lower enhancement, and it is causing encasement of the celiac vessels and SMA artery, and there was also a left moderate lesion due to the mass effect of the lesion. This is an heterogeneously hypodense solid lesion noted at the Heiler Mission of the liver, which is showing the heterogeneous enhancement of the contrast with non-enhancing areas like the necrosis, and the CVD is dilated with the enhanced solid part within it. This is the case we initially thought it as a TB, because these are the necrotic lymph nodes and because there is also an ascites. This is an heterogeneously enhancing hypodense solid lesion noted in the inferior aspect of the right lung. These are my references. Thank you.
