Giant aneurysm of an aortopulmonary collateral

We present an unusual case of a giant aneurysm of an aortopulmonary collateral, in a patient of Tetralogy of Fallot with pulmonary atresia on long-term conservative treatment. Aneurysm of aortopulmonary collateral is an extremely rare finding. Only a few similar cases have been reported in literature.
 

CT diagnosis of Cecal Diverticulitis

Cecal diverticulitis has a high incidence among Asians, but is a rare condition in the western world. Cecal diverticulitis is not a common disease, becoming clinically evident between the second and the fourth decade. The diagnosis of cecal diverticulitis is often controversial since the signs and symptoms simulate an acute appendicitis or an appendicular abscess. Moreover, during surgery, sometimes it appears like carcinoma of the cecum. CT scanning is a sensitive means by which to detect cecal diverticulitis. We are presenting the CT findings of a case of cecal diverticulitis.
 

Helical CT evaluation of Aortopulmonary window

Aortopulmonary window is an opening between the aorta and the pulmonary trunk. Two distinct separated semilunar valves must exist to establish the diagnosis of aortopulmonary window, and this defect should be differentiated from truncus arteriosus. Aortopulmonary window is generally diagnosed by echocardiography or Angiocardiography. The authors present two cases of Aortopulmonary window diagnosed by helical CT.
 

Transient hepatic attenuation difference (Thad) – A Case Report

THADs are associated with a large variety of liver disorders-Portal or hepatic vein thrombosis, cirrhosis, Budd- Chiari syndrome, biliary obstruction, trauma ,focal hepatic lesions and aberrant blood supply. THADs that are associated with hepatic tumors are generally characteristic of malignant tumors. However, benign focal lesions, such as hemangiomas, focal nodular hyperplasia, pyogenic abscess and focal eosinophilic necrosis, may accompany THADs.
 

Total anomalous pulmonary venous connection: helical computed tomography as an alternative to angiography

Echocardiographic evaluation of the pulmonary veins is inadequate at times. Cardiac catheterization, especially in sick neonates, may be a high-risk procedure. Helical computed tomography with three-dimensional reconstruction is noninvasive but remains an underutilized modality.
