Role of CT Perfusion in Identifying the Core and the Potentially Salvageable Penumbra in Patients with Acute Non Haemorrhagic Stroke - Experience at Tertiary Care Center.

OBJECTIVES: To evaluate the role of CT Perfusion in Identifying the core and the potentially salvageable penumbra in brain infarcts by observing perfusion maps (CBV, CBF and MTT). Also to identify patients who would benefit from reperfusion therapy and to evaluate the feasibility of identifying the penumbra on noncontrast CT vide comparison with perfusion maps. MATERIALS AND METHODS: A prospective study of 50 patients who presented with acute onset neurological deficit within 6 hours of symptom onset and in whom initial NCCT revealed no evidence of cerebral hemorrhage; evaluated with CT Perfusion was done at tertiary care center in 1 calender year 2014. OBSERVATIONS: In our study, about 68 percent of patients presented within 6 hours of stroke had salvagebale penumbra, were eligible for revascularization therapy. HU less than 25 on NECT significantly correlated with infract core but not with presence of Penumbra. Presence of penumbra cannot be predicted from NECT ASPECT and CBV ASPECT Score. RESULTS AND CONCLUSION: CT Perfusions study being easily available, faster and cost effctive modality to identfy patients of acute ischemic strokes having salvagable penumbra for which further can be subjected to revasculrization therapy. It is strongly recommended that CT Perfusion should be made an integral part of acute non-haemorrhagic stroke management protocol, wherever the facility is available.

Ectopic Pregnancy in caesarean section scar: A case report.

We report a rare case of ectopic pregnancy occurring in the scar of a previous caesarean section, diagnosed by ultrasonography and confirmed by 3.0-T magnetic resonance imaging of pelvis. We present the clinical details and imaging findings, followed by discussion of the etiology, pathogenesis, and imaging of this condition.

Radiologic features of hydatid disease: the importance of sonography.

Hydatid disease is commonly encountered in specific geographic areas of the world. Hydatidosis affects multiple organs and has diverse radiologic presentations. Sonography remains an important modality for diagnosing this condition, as it optimally detects cystic structures, floating membranes, and debris. Sonography forms the crux of radiologic diagnosis of hydatid disease. It not only helps diagnose the disease but also aids in guiding therapeutic interventions. The main objective of this article is to describe the imaging features of hydatid disease in its various stages. This article gives an overview of the spectrum of sonographic manifestations of hydatid disease in various locations, along with common differential diagnoses. A brief description of therapeutic management is also presented.

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.
