Images reveal innumerable cysts in bilateral basal ganglia (arrows in a and b) and cerebral hemispheres, giving the “starrysky〞 pattern. A few lesions demonstrate perifocal oedema and ringenhancement (arrows in c and d) suggestive of the colloid vesicular stage 第五十八頁(yè),共六十八頁(yè)。 ? MRI. Sagittal brain T2W images show cysticerci in the extraorbital muscles (arrow) (a) and tongue (arrows) (b) as well as in the cranial and cervical muscles. c Sagittal spine T2W image reveals hyperintense lesions in nearly every paraspinal muscle (arrows) 第五十九頁(yè),共六十八頁(yè)。 Treatment ? The indications of treatment of cerebral cysticercosis are controversial有爭(zhēng)論的 . ? However, patients with symptomatic neurologic involvement (usually seizures) and either meningitis or one or more noncalcified非鈣化的intraparenchymal cysts should be treated. ? Intraventricular, subarachnoid, and racemose cysts respond poorly to treatment ? Calcified cysts do not require treatment. 第六十頁(yè),共六十八頁(yè)。 ? Albendazole, 阿苯達(dá)唑 15mg/kg/d in three doses taken with meals, and continued for 8 days, is the preferred therapy. ? Praziquantel, 吡喹酮 50mg/kg/d in three divided doses, can also be used, but blood levels are reduced by anticonvulsants 抗驚厥藥 and corticosteroids皮質(zhì)類(lèi)固醇 , which are often required in these patients. 第六十一頁(yè),共六十八頁(yè)。 ? Patients with seizures should also receive anticonvulsants. ? Corticosteroids are indicated for increased intracranial pressure or lesions near the cerebral aqueduct中腦導(dǎo)水管 or intraventricular foramina室間孔 。 these may progress to cause obstructive hydrocephalus梗阻性腦積水 . ? Single accessible intraparenchymal 腦實(shí)質(zhì)內(nèi)lesions can be removed surgically, and shunting分流術(shù) is required for intraventricular lesions causing hydrocephalus. 第六十二頁(yè),共六十八頁(yè)。 第六十三頁(yè),共六十八頁(yè)。 第六十四頁(yè),共六十八頁(yè)。 第六十五頁(yè),共六十八頁(yè)。 第六十六頁(yè),共六十八頁(yè)。 第六十七頁(yè),共六十八頁(yè)。 內(nèi)容總結(jié) TUBERCULOUS MENINGITIS。 Treatment。藥物治療原那么:早期、聯(lián)合、足量、長(zhǎng)期、頓服 第六十八頁(yè),共六十八頁(yè)。
