 Coming to the vascular legions of the salivary gland, see this case of a three-month-old female child. The mother noticed a swelling on the left aspect of the neck, bluish discoloration of the skin, referred by the pediatrician for further evaluation. See this clinical picture where we can see this bluish discoloration of the skin and when we did the imaging, we saw that in the superficial subcutaneous sub-tissues, there was this ecogenic legion at senior and when we evaluated it with Doppler, we see that this legion showed vascularity and the spectral evaluation showed that it typically showed a low-grade venous flow and that is classically suggestive of a low-grade venous malformation. So, vascular morphogenes are these congenital legions which are there since birth and they could be classified into capillary lymphatic arterial venous and depending upon its clinical picture and ultrasound findings, you can make a diagnosis of a low-grade venous malformation. Also, see this case of a female child with swelling along the right parotid region. So, when we evaluated this case, the submandibular glands on the right and left are completely normal. The left parotid gland is normal but look at this right parotid gland. It shows some inhomogeneous appearance with some anechoic area seen within and see this video, you realize that there are multiple hyper-echoic process with shadowing seen within this gland architectural which is distorted and this are classically nothing but flabellets and whenever you see flabellets within this legion, always always think in terms of hemangermas. So, hemangermas are also could be two types depending upon the way they could be capillary or cavernous and these cavernous hemangermas are seen more commonly in the older children. Now, ultrasound and bupala can really evaluate flat-stooling regions in a very good way and you can make a confident diagnosis of a hemangerma or venous malformation on ultrasound. Now, depending upon the pattern of flow, they could be low flow types or high flow type. Then see this case of a four-month-old female child with the history of rapidly increasing swelling along the right carotid region. In fact, this mother said that there was a small swelling and now this has suddenly increased in size. So, when you evaluated this gland, you could see that the left carotid gland was completely normal. When you look at this right carotid gland, it is enlarged, inhomogeneous in eco-texture. You can appreciate this. When you evaluated it with bupala, it showed a carotid vascular pattern all within the gland and mind you, whenever you have such a kind of history, the first diagnosis you should think in terms of a carotid hemangio endotheloma. So, it is one of the most common carotid tumor of the childhood and whenever you have this history of any rapidly large growing mass in an infant in a carotid, first diagnosis which should run in your mind is a carotid hemangio endotheloma. The more case which we saw of a seven-year-old female child with history of swelling along inferior to the angle of mandible. Now, clinically, this region was compressible and soft and hence when we started imaging, we saw that along the angle of the mandible, there was this inhomogeneous appearing region with two anechoic areas within it. When we started evaluating with bupala, we could get both a red and blue signal seen within it. And when we deeply evaluated this region, we saw that it typically had a branching pattern. It showed arterial and venous both flow. In fact, you could see that a large draining vein we could appreciate in this region. We saw this region on spectrum evaluation. We could see that the veins have got completely arterialized and show a high flow of almost 200 meters per second. Whenever you have an arterial venous mixed signals with veins being arterialized and a draining vein seen, this is nothing but an avian. Now, in fact, in this case, when we did literature search, we found that submandible avians are quite rare. But peracted avians are very commonly seen in pediatric age group in the peracted gland. In fact, with my search, I found that there were only eight cases of submandible avian reported to the day and maybe this is the ninth one. So, coming to the end of the discussion, one can confidently say that this history age group known of the patient and also looking at these patterns the way these regions present and always bearing in mind where the age and the history in many cases of peracted and submandible avian, you can make confident evaluation of the region and give them diagnosis. Thank you.
