"Evaluation of Mandibular Pathologies By MDCT and Denta Scan Software"

Multislice Spiral CT (Computed tomography) has become the modality of choice for evaluation of maxillofacial and mandibular pathologies in the recent years. The development of dental CT reformatting programs has completely revolutionized and changed the fashion to radiographically evaluate the jaw today. The study is based on the prospective evaluation of 60 patients with symptomatology related to mandible, using MDCT (Multidetector Computed Tomography) with its special Denta scan software and 3-D display techniques. The study aims at studying the imaging spectrum of various mandibular pathologies by MDCT to formulate a diagnosis and to assess the extent and involvement of adjacent structures thereby to substantiate the utility of MDCT in the management of these pathologies

Endovascular Stent Graft for Post-traumatic Superficial Femoral Artery Pseudoaneurysms with Arteriovenous Fistula: 6 Months Follow-Up of 2 Cases

Pseudoaneurysms are common vascular abnormalities due to disruption of the vessel wall. Pseudoaneurysm with arteriovenous fistula is a rare presentation. Complications associated with them develop unpredictably and carry a high mortality rate. Traditionally pseudoaneurysms have been treated surgically. However, with the advent of new interventional techniques, management using endovascular approach have gained popularity in treating pseudoaneurysms. Here, we present two cases of large pseudoaneurysms with arteriovenous fistula treated by percutaneous stent graft. Present studies on pseudoaneurysms are all either iatrogenic or secondary to nephrologic dialysis treatment and only few present studies exist describing such large post-traumatic femoral pseudoaneurysms with arteriovenous fistulas were treated successfully by stent grafting through femoral approach, with good patency at 6 months follow up

Rare case of giant chorioangioma and review of literature

Placental tumours are classified into trophoblastic and nontrophoblastic tumours. Nontrphoblastic tumours are relatively rare which includes chorioangioma/placental hemangioma, placental teratoma, placental metastatis. Chorioangioma has a prevalence of 1% among other placental tumours. Giant chorioangioma is relatively rare. Chorioangioma may be associated with adverse fetal and maternal complications. Fetal complications may include intrauterine fetal growth retardation, fetal anemia, polyhydramnios and maternal complications may include pregnancy induced hypertension, antepartum hemorrhage, preterm labour. Untoward complications can be avoided by timely detection, appropriate follow up and management. We report a case of giant chorioangioma and its outcome

Communicating Tubular Duplication of Upper Esophagus–A Rare Occurrence

Duplications of esophagus are commonly classified into two types, tubular and cystic. Tubular duplication of esophagus is a rare occurrence and is much less common than cystic duplication of foregut. Most esophageal duplications are located in the lower third of the esophagus. A cervical esophageal duplication is extremely rare. Esophageal duplications have been reported twice as commonly on the right as on the left. We report a case of incidental finding identified on computed tomography of communicating tubular esophageal duplication involving the left side of the upper esophagus in a tuberculosis patient that was subsequently confirmed on barium swallow test

Large gastric perforation sealed by splenic lysis : emphasis on indirect signs : a rare case report

BACKGROUND: Gastric perforation is a life-threatening condition, requiring early and reliable discovery. The delay before surgical treatment is a strong determinant of poor outcome, associated complications and hospitalization costs. By using ultrasound and multi-detector computed tomography (MDCT) we can further evaluate undiagnosed cases of silent gastric perforations presenting with non-specific acute abdomen. Here we bring forth the role of a radiologist in cases of perforation which present with indirect signs involving the organs forming the stomach bed, like the spleen, pancreas and kidney. CASE REPORT: A 25-year-old male patient presented with an acute onset of severe upper abdominal pain radiating to the back and vomiting. MDCT of the abdomen was done which revealed atrophic pancreas with organized collection in the sub-capsular location indenting the superior pole of the left kidney. Spleen was not visualized. The most striking imaging finding in that case was destruction of the splenic parenchyma with protrusion of the remaining tissue into the stomach lumen. The hypothesis behind this was a cascade of events which started with gastric perforation, spillage of highly destructive gastric juice over the stomach bed and finally becoming silent with rapid sealing of the defect by the omentum and the spleen. CONCLUSIONS: Acute abdomen is a diagnostic challenge to a clinician and radiologist with gastric perforation being a great mimicker of other urgent abdominal pathologies. To avoid a delayed diagnosis or a misdiagnosis, familiarity with typical and atypical imaging features is essential as in our case of splenic lysis. It acted as the 2nd policeman and provided a great clue to solve the diagnostic dilemma
