 I'm Dr. Nisreen Moidin, post-graduate resident from Pushpagiri Hospital, Tiruvalla. My paper is on cross-sectional imaging of spectrum of pediatric chest and abdomen tumors of pictorial acid. Childhood cancers are relatively bad. However, cancer is the second leading cause of death among children following only injuries. The spectrum of sputuristic mass lesions accounted in radiology factories differs greatly in children compared to adults. Eukemia is by far the most common followed by brain tumors, then the lymphomas and then the certain bone cancers such as osteosarcoma and even sarcoma. The aim of my paper is to discuss the spectrum of pediatric chest and abdomen tumors and to illustrate the same in the form of a pictorial assay. Methods, we have reviewed the CTMR images of a number of pediatric patients who were diagnosed with chest and abdomen neoplasms based on imaging findings. And these were compared with the pathological of both and a detailed pictorial assay is illustrated. Results, in the imaging studies we conducted, we encountered few common cases like neuroblastoma, ganglionuroma, as well as rare ones like pleuro pulmonary blastoma, montyloclastic renal oncocytoma, et cetera. Cross-sectional imaging modalities, henceforth, proved to be the key in the diagnosis and subsequent management of these patients. So let us begin the discussion. Case number one, the 17-year-old girl presented to our department with complaints of fever, cough, breathing difficulty, fatigue, and weight loss. Scanogram showed a well-defined homogeneous soft tissue density, lenticular shaped mass lesion, brought waste to the media standard with losses ahead with the cardiac border. CTS sections show a well-defined heterogeneous mixed-density lesion consisting of fat, calcification, and cystic areas involving the media syndrome on the right side. In view of the mixed densities, we gave the diagonal, we gave the possibility of mature teratoma. Biopsy came as benign mature teratoma, which again contains the elements from all the three embryological layers. Most common, extroconodal jumps and tumor, maturity, antidepressant, media stina. Case number two, 11-month-old boy presenting with recurrent fever, irritability, and seborrheic dermatitis like skin lesions. Chest x-ray frontal projection showed superior media standard widening, caused by enlarged timing shadow, and skull x-ray showed a lytic lesion involving the superlateral aspect of left orbit. CTS section showed a heterogeneously enhancing lesion with bony resorption involving the superlateral aspect of left orbit. Here we see diffusely enlarged timers with multiple full-safe calcifications. Lung field showed multiple tiny nodule scattered along with the interlobular septal thickening and multiple cystic foci. The bilateral parotid glands were also found to be diffusely enlarged. Hepatomegallae and modally enlarged spleen and lymph nodal mass along external iliac regions bilaterally. The patient was diagnosed to have longer hand cell histiocytosis. Next case, two-year-old boy presented with cuff of two weeks duration and chest radiograph revealing a shadow. Again, lendicular shape, broad-based to the media standard. This time, the cardiac cell header is preserved. On MRI images, we could see a lendicular shape, homogeneous signal intense mass lesion, broad-based to the spine involving the right paraspinal region. On CT, showed a homogeneous soft tissue alternation with multiple foci of calcification. The diagnosis came as ganglia neuroma, which is a benign tumor originating from neurocrustaceous paraspinal media stymium being one of the most common locations. Case number four, two-year-old child with recent onset respiratory distress and cough. Chest x-ray frontal projection showed completely a pacifier left hemithorax with relative sparing of the upper zone, causing media stymial and tracheal shift towards right side. CTs, such as also show the same. This time, a soft tissue alternation is homogeneous here, resulting in a mass lesion causing media stymial and tracheal shift towards right side. On post-contrast, there is a heterogeneous enhancement with many vascular channels taking up the contrast. Diagnosis came as pluripulmonary blastoma. Case number five, imaging of a three-day old child who had an antinately-detected abdominal mass revealed. Well-defined rounded hyperdense lesion cascaloping the inferior surface of the liver or on top of the upper polar fried kidney. On post-contrast, the lesion showed heterogeneous enhancement. The diagnosis came as adrenal neuroblastoma, of which the adrenal medulla is the most common site. Next case, another new unit, a two-day old boy detected to have an abdominal mass prenatally. My major showed a thick wall cystic lesion with solid areas within. On post-contrast, we could see a nodulatic enhancement along the periphery with central area not taking up the contrast. And again, the biopsy revealed a hematioendopathyoma, which is the third most common hepatic tumor of the children. Next case, a three-year-old girl detected to have a painless abdominal mass on routine examination. We see a multi-loculated cystic large mass involving the lower polar fried kidney. The fibrous scar showing enhancement on post-contrast. The biopsy came as multi-locular cystic renal oncocytoma, which usually presents as, oncocytomas usually present as a solid mass with central fibrous scar, but such a presentation is very rare. Our last case, 14-year-old male came with incidental finding of adrenal lesion on USDA abdomen following trauma. No history of abdominal pain or increased palpitation. CT test showed a well-defined rounded mass lesion of homogeneous attenuation involving the expected location of right adrenal gland on top of the right kidney. On post-contrast, the lesion showed heterogeneous enhancement, which seemed to persist into the delayed phase. The resection was done, and the biopsy came as ganglia neuroma. We indeed gave this possibility along with since we did not see any fat densities within, we also gave the possibility of anchomyelipum with minimal fat. So a conclusion, the spectrum of pediatric chest and abdomen tumors were identified and studied along with their close differences based on radiopathological correlation. The study proved that though imaging studies performed with caution in the young, however, an imperative part in accurately diagnosing the various neoplasms. These are my references. Thank you.
