OBJECTIVETo study the value of MRI in the diagnosis of cerebral sparganosis in children.

METHODSThe MRI appearances of 17 children with cerebral sparganosis proven by pathology or serological test were retrospectively studied. The diagnostic accuracy rate of cerebral sparganosis was compared before and after knowing the imaging features of this disease.

RESULTSEnhanced MRI was performed in 12 cases, and all of them demonstrated abnormal enhancement. Peripheral ring-type, tortuous beaded shape or serpiginous tubular shape enhancement were found in 8 cases. After analysis of follow-up MRI for 7 cases, a change in location and shape of lesions was found in 2 cases. Typical MRI patterns of cerebral sparganosis included abnormal enhancement such as peripheral ring-type, tortuous beaded shape or serpiginous tubular shape enhancement, and changes in location and shape of lesions in the follow-up MRI. The diagnostic accuracy rate for the 17 cases of cerebral sparganosis at the first visit, after first imaging examination and after several follow-up MR examinations were 0%, 11.8% and 28.6%, respectively. The diagnostic accuracy rate of this disease increased to 64.7%, 70.6% and 85.7% respectively after the radiologists were trained in the imaging characteristics of the disease.

CONCLUSIONSMR findings in children with cerebral sparganosis are specific. Mastering correctly the typical imaging features of the disease can be very helpful in reducing the rate of clinical misdiagnosis.

Neurocysticercosis*

In 1996, the center for image diagnosis implemented CT scanner on 20 patients to identify cerebral cysticercosis. The results showed that the male/female patient rate was 4/1. The cysticercosis located mainly in brain, under skin and muscle. If cysticercosis found in brain, it should find cysticercosis whether is in the skin and muscle or not. And if the cysticercosis found in the skin and muscle and there is an intracranial hyperpressure, it should find the cysticercosis in the brain

Neuroschistosomiasis is a serious complication of schistosomiasis, where Schistosoma parasites migrate to the central nervous system. It is often overlooked but can cause significant neurological symptoms. We present a 10-year-old male with headache and papilledema, emphasizing the importance of considering neuroschistosomiasis in patients with neurological symptoms and a history of schistosomiasis exposure. Early diagnosis and timely treatment with antischistosomal drugs and corticosteroids are crucial for positive outcomes. Raising awareness and implementing appropriate management approaches can improve the prognosis of neuroschistosomiasis.

The authors had performed stereotactic surgery to diagnose and treat 2 cases of neurocysticercosis under the local anethesia. Generally, such the open surgery need a general anethesia which may increase the chance of brain parenchyml injury. However, the stereotactic surgery has the advantage of being an easy and precise procedure under local anethesia. The authors reviewed the literature and discussed the stereotactic surgery in the diagnosis, and treatment of neurocysticercosis.

Trapped fourth ventricle is a rare clinical entity. It presents as a posterior fossa mass lesion. A case of trapped fourth ventricle which developed after surgery of cystic neurocysticercosis located at the cerebellopontine angle is presented. The authors reviewed the literatures of the trapped fourth ventricle and discussed the pathogenesis as well as the management of this rare clinical entity.

The authors report two cases of radiologically documented transaqueductal migration of intraventricular neurocysticercus cysts. The patients had suffered from symptomatic hydrocephalus caused by neurocysticercosis. The migration of the cysts from third to forth ventricle and cisterna magna were clearly demonstrated on serial radiological studies. Since the exact route of the subarachnoid type of the neurocysticercosis has not been defined, these cases may provide a valuable clue in verifying the pathogenic pathway. The possibility of the cyst migration before surgery also should be kept in mind. The radiological appearance and the clinical significance of this condition are discussed with brief review of literatures.

Cysticercosis is the most common parasitic infection affecting the central nervous system. Spinal neurocysticercosis (NCC) is very rare compared with intracranial NCC and requires more aggressive management because these lesions are poorly tolerated. The authors report a case of intradural extramedullary cysticercosis of the entire level of spine with review of the literature.

We report a 30-year-old woman with neurocysticercosis, who showed convergence and convergence-retraction nystagmus, V-bobbing, and typical findings of pretectal syndrome due to shunt malfunction. The symptoms and signs improved with shunt revision. The co-development of convergence, convergence-evoked, and convergence-retraction nystagmus, and pretectal pseudobobbing in our patient indicates that these ocular movements may share common pathophysiology of imbalance in the vergence system.

Papilledema, pupillary abnormalities, and nystagmus are common neuro-ophthalmologic signs in neurocysticercosis (NCC). Oculomotor palsy rarely occurs and usually accompanies compression of the midbrain by supratentorial or subarachonoid lesions with or without inflammation and hydrocephalus. Oculomotor palsy from NCC involving the midbrain parenchyme has rarely been described. We report on a patient who presented with oculomotor palsy caused by mesencephalic NCC. The patient showed recurrences of symptoms in association with steroid tapering.
