Findings
Axial T2, FLAIR, DWI, T1, post contrast T1 and sagittal T2 images of brain reveal a small ring enhancing T2 hyperintense, T1 hypointense lesion showing complete suppression of signal on FLAIR sequence, a tiny eccentric T2 hypointense focus (scolex) in anterior aspect of right superior temporal gyrus with moderate adjacent vasogenic edema. The lesion shows mass effect in the form of effacement of overlying sulcal spaces, compression of adjacent lateral ventricle and minimal contralateral midline shift.
Diagnosis
Colloidal vesicular Neurocysticercosis (NCC)
Summary
Neurocysticercosis is a neurologic parasitic disease caused by the encysted larva of the tapeworm Taenia solium. It is the most common cause of acquired epilepsy in endemic settings. With respect to location, it has traditionally been classified into subarachnoid-cisternal (most common), parenchymal, intraventricular, and spinal forms. On the basis of radiologic findings, neurocysticercosis is divided into five stages: noncystic, vesicular, colloidal vesicular, granular nodular, and calcified nodular. Associated complications include vascular involvement (arteritis with or without infarction), inflammatory response (edema, gliosis, or arachnoiditis), and obstruction in ventricular forms.
