Cebocephaly and sirenomelia are uncommon birth defects. Their association is extremely rare; however, the presence of spina bifida with both conditions is not unexpected. We report on a female still-birth with cebocephaly, alobar holoprosencephaly, cleft palate, lumbar spina bifida, sirenomelia, a single umbilical artery, and a 46,XX karyotype, but without maternal diabetes mellitus. Our case a...

Figure 2: MIPs of 1.5T (a) and 7T (b) PC MRA of the vasculature superior to the circle of Willis of a 39 year old, male volunteer. The acquisitions times for both sequences were about 5 minutes. Axial images were acquired with slices thickness of 0.75 mm. The 7T images depict third order branches of the circle of Willis, e.g. the paracentral artery. Ultrahigh Field (>7T) Time-of-Flight and Phas...

249 Fig. 2. Computed tomography scan (axial section) shows a left proximal occipital artery pseudoaneurysm. Fig. 1. Preoperative photograph showing a lesion on the left neck. nodules recovered completely without scarring. Therefore, physicians who perform aesthetic procedures should be aware that late-onset painful nodules are likely to be caused by a bacterial infection such as MRSA, and ident...

Isolated dissection of the posterior cerebral artery (PCA) is a rare but important cause of stroke in younger patients, particularly women. We present 3 cases of dissection of the P2 segment of the PCA. In 2 patients, an association with minor axial head trauma was documented, suggesting shearing injury of the PCA as it crosses over the free edge of the tentorium. The clinical and imaging findi...

A previously fit 35 year old man presented with a right hemiparesis and dysphasia 36 hours after abuse of Ecstasy (3,4-methylenedioxymethamphetamine). Computerized axial tomography scan demonstrated an extensive acute left cerebral infarction and carotid digital subtraction angiogram, 2 days after admission, revealed left middle cerebral artery occlusion. There were no other known risk factors ...

Neurology India | Jan-Feb 2009 | Vol 57 | Issue 1 Figure 2: Axial contrast-enhanced T1W MRI (a) shows diffuse enhancement of the wall of the right intra-petrous ICA (arrow). Ethmoid and sphenoid sinusitis is also seen. 3D contrast-enhanced MR angiogram (b) shows long segment narrowing of the right ICA (arrow). The left ICA is normal (black arrow) Cavernous sinus thrombophlebitis causing reversi...

deficits. There was no history of head injury or surgery. Plain radiographs of skull showed irregular calcifications in the left temporal region (Figure 1). Computed tomography (CT) of brain revealed a heterogeneous extra axial lesion in the anterior aspect of left temporal fossa and left middle cerebral artery cistern, showing calcification, soft tissue and fat density. Multiple tiny fat dropl...

A mathematical model is developed for hemodynamic transport of a reactive diffusing species e.g., oxygen in rigid artery under constant axial pressure gradient and undergoing first-order chemical reaction with streaming blood. two-fluid deployed where the core region simulated as an Eringen micropolar fluid, plasma layer engulfing core, i.e., near boundary, analyzed Newtonian viscous fluid. Clo...

BACKGROUND AND PURPOSE Visualization of the intracranial internal carotid artery (ICA) with transcranial color-coded sonography (TCCS) by using the transtemporal coronal plane has been described previously. Because this approach is limited to the vertical running ICA segments, we investigated the feasibility of using TCCS to visualize all intracranial ICA segments by adding the transtemporal ax...

1 ABSTRACT Arteriovenous (AV) fistula is the most preferred form of vascular access for end-stage renal disease patients. Acute changes in hemodynamics and in particular wall shear stress (WSS) immediately after fistula placement are followed by the dilation of the vasculature luminal area to recover the normal physiological condition before surgery. However, vasodilation in AV fistula is not w...
