MRA-based 3D-printed heart model-an effective tool in the pre-surgical planning of DORV.

A three-dimensional (3D) printed heart model based on contrast-enhanced MR angiography data was obtained in an 8-month-old male child with double-outlet right ventricle. The model could successfully show the spatial relationship between the aortic annulus, the pulmonary valve and the ventricular septal defect. The patient underwent complete intracardiac repair based on the 3D model. MR angiography images could be successfully used to create a true-size 3D heart model, which significantly helped in assessing the routability of the ventricular septal defect to the aorta, leading to successful intracardiac repair in our patient.

Synchronous infection of the aorta and the testis: emphysematous epididymo-orchitis, abdominal aortic mycotic aneurysm, and testicular artery pseudoaneurysm diagnosed by use of MDCT.

We report clinical details and imaging findings for a case of emphysematous epididymo-orchitis with co-existing mycotic abdominal aortic aneurysm and a testicular artery pseudoaneurysm in a diabetic 65-year-old male. We report imaging findings from ultrasonography (USG) and contrast-enhanced multidetector computed tomography (MDCT). Use of MDCT to identify, confirm, and define the extent of the disease, and its utility in understanding the pathogenesis of this rare condition are highlighted. For such lethal infections, early diagnosis and intervention can be lifesaving; imaging can be of crucial importance in this.

Horse-shoe lung-rediscovered via volume rendered images.

Horseshoe lung, usually associated with pulmonary venolobar syndrome, is a rare congenital anomaly involving the fusion of the postero-basal segments of the right and left lungs across the midline. The fused segment or the isthmus lies posterior to the pericardium and anterior to the aorta. The associated pulmonary venolobar syndrome involves anomalous systemic arterial supply and anomlaous systemic venous drainage of the right lung. With the advent of MDCT imaging, we can diagnose this rare condition as well all its associated anomalies non-invasively. Volume-rendered techniques greatly simplify the complex anatomy and provide easy understanding of the same.

Absent pulmonary valve syndrome with tetralogy of Fallot and associated dextrocardia detected at an early gestational age of 26 weeks.

Absent pulmonary valve syndrome is a rare congenital anomaly, usually seen in association with a ventricular septal defect. It has been reported to occur in 3-6% of cases of tetralogy of Fallot. Absence of the pulmonary valve results in a dilated main pulmonary artery, which can be seen as a cystic, pulsatile, paracardiac lesion on antenatal USG. Such a lesion, though rare, can easily be detected. We report a case of this rare anomaly which was present in association with a ventricular septal defect, tetralogy of Fallot, and dextrocardia. The case was detected at 26 weeks of gestation.

Complete large bowel duplication with paraduodenal cyst: prenatal sonographic features.

OBJECTIVES: To illustrate diagnostic dilemmas while considering a diagnosis of complete large bowel duplication and duodenal duplication cysts. METHODS: A case of large bowel dilatation with a peripancreatic cyst was identified sonographically in a 27-year-old gravida 3 at 35 weeks of gestation, suffering from gestational diabetes and pregnancy-induced hypertension. RESULTS: On the basis of sonographic findings of dilated, hyperperistaltic large bowel loops, and a large cyst with echo-free contents near the pancreas, a diagnosis of large bowel obstruction with a paraduodenal cyst was considered. The findings were confirmed after postnatal ultrasonography. At the time of surgery, it proved to be a completely duplicated large bowel with a paraduodenal cyst. CONCLUSION: Prenatal findings of a hugely dilated, hyperperistaltic large bowel should lead one to suspect/consider large bowel duplication. Associated cysts are likely to be bowel duplication cysts. Timely intervention can thus obviate potentially serious complications.
