Cerebral sparganosis is a rare parasitic disease caused by infestation by the plerocercoid larva of Spirometra mansoni. The authors retrospectively analyzed 17 cases of cerebral sparganosis treated at Seoul National University Hospital between 1986 and 1994. The patients' ages at diagnosis ranged from 6 to 57 years (median 32 years) and the male/female ratio was 13:4. Diagnosis was based on radiological findings, serological test results, operative findings, and histopathological examinations. Characteristic magnetic resonance (MR) findings consisted of widespread white matter degeneration and cortical atrophy, mixed-signal lesion (low in the central and high in the peripheral regions on T2-weighted images) with irregular dense enhancement of central foci and changes in the location and shape of the enhancing lesion in follow-up studies. Ten patients underwent surgical removal of the parasitic lesion, six received medical treatment alone (five with praziquantel and one with antiepileptic drugs), and one underwent insertion of a ventriculoperitoneal shunt and a course of praziquantel. Follow-up periods ranged from 13 to 111 months (mean 49 months). Seven patients who underwent complete removal of the lesion, live worm, or degenerative worm with surrounding granuloma showed a favorable course. Patients who received medical treatment alone or incomplete removal exhibited progression in their neurological deficits and their seizures could not be controlled. Medication with praziquantel seemed to have no killing effect on live worms. The authors conclude that MR imaging is the most valuable modality for the early detection of cerebral sparganosis and that complete surgical removal of granuloma together with worms, whether they are alive or degenerative, is the treatment of choice.

Neurocysticercosis is an important public health problem in South-Central American and South Asia. A review of the differences in epidemiological and clinical attributes of cysticercosis and taeniasis in South Central America and India, respectively, is undertaken in the present communication. Intestinal taeniasis is hyperendemic in several American countries. In comparison, the prevalence of Taenia solium infestation is lower in India. The clinical manifestations in several American neurocysticercosis series comprise epilepsy, intracranial hypertension and meningeal-racemose cysticercosis, in roughly equal proportions. An overwhelming majority of the Indian subjects present with seizures. The commonest pathological substrate of the disorder in Indian patients is the solitary parenchymal degenerating cyst. The reasons for the predominance of solitary forms in India, and of multilesional forms in South Central America are discussed. The magnitude of Taenia solium infestation and the frequency of pork consumption in a given population appear to influence the quantum of cyst load in affected individuals.

Epilepsy is a major public health threat in the developing world, with much higher prevalence and incidence rates than those observed in developed countries. At present, one of the most common causes for epilepsy worldwide is the parasitic worm, Taenia solium, and the associated neurocysticercosis (NCC) that may often result from this infestation. Worm infestation was already recognized as a cause of epilepsy by the middle of the 18th century. Helminths and their effects on health were a daily medical concern in the 18th and 19th centuries--with prevailing views ranging from the beneficial effects of the presence of adult worms in the gut, to considering them as culprits for a wide variety of diseases. A number of cases followed longitudinally by various nineteenth-century French physicians showed that there was good reason to believe that the verminous influence on seizures was real, as the expulsion of the T. solium often coincided with a notable amelioration of symptoms. Several theories were proposed to account for how the worms could lead to Epilepsia nervosa, including notions of competition for nutritional resources between the host and the parasite, and irritation of the medulla and of peripheral nerve endings predisposing to epileptiform episodes. Recently, after almost a century of quiet, interest in the neurological effects of helminths has been rekindled, due in part to the growing number of cases in the United States with NCC-related neurological disorders. In this article, we review the history of our understanding of the relationship between seizure disorders and parasitic worms, and we relate this history to contemporary epidemiologic and public health issues in developing countries.

Cysticercosis is an infestation of Cysticercus cellulosae. When it occurs in the brain, chronic neurological complications can ensue, most commonly seizures. Neurocysticercosis is usually diagnosed by neuroimaging, a technique not available in most endemic countries. Hence immunological tests are valuable for diagnosis and epidemiological surveys. We evaluated the suitability of paper for storing blood and cerebrospinal fluid (CSF) until subsequent testing by enzyme-linked immunosorbent assay (ELISA), by testing whole blood samples on filter paper from 305 patients and CSF samples from 117 patients stored on ordinary white typing paper and on filter paper. Optimal preservation of biological samples is achieved when whole blood is stored on filter paper, CSF on white paper, and when samples are frozen within 1 week after collection. Our results could improve diagnostic capabilities and facilitate epidemiological surveys in endemic countries where immunodiagnostic tests cannot be rapidly performed because of inadequate laboratory infrastructure.

Cysticercosis is a human infestation, which is considered the most common cause of seizures worldwide. The subcutaneous lesions can help in the diagnosis of neurocysticercosis. We describe a case of a 45-year-old patient with multiple cutaneous nodules first seen 2 years ago that were increasing in number, and normal neurologic and fundoscopic examination. Neurologic symptoms started 3 months before hospital admission as a mild headache and muscular weakness. The imaging examinations showed a massive central nervous system involvement. Physicians must be aware of the importance of subcutaneous nodule examination for the diagnosis of neurocysticercosis.

Lymph node enlargement due to cysticercus infestation has not been reported in human subjects. A 7-y-old girl presented with seizures and a right submandibular lymph node enlargement. Investigations showed inflammatory granulomas in the brain. Fine needle aspiration cytology from submandibular lymph node and enzyme-linked immunosorbent assay of serum and cerebrospinal fluid showed the presence of cysticercosis infestation. The case underlines the potential of fine needle aspiration cytology for establishing diagnosis in patients having enlarged lymph nodes.

Neurocysticercosis is the most common parasitic infestation involving the central nervous system in tropical countries. Common presentations are seizure, meningitis and increased intracranial pressure. The authors report a case of a 52-year-old woman with racemose neurocysticercosis in the subarachnoid space at the cistern of the brain through the lumbar cistern. She presented with progressive paraparesis due to spinal cord compression and finally had progressive bilateral sensori-neural hearing loss. MRI brain and the whole spinal cord revealed numerous rim-enhancing cystic lesions at the basal cistern, prepontine cistern, bilateral cerebellopontine angle, internal acoustic canals, intramedullary lesion at the 5th cervical spinal level, lumbar cistern lesions and secondary syringomyelia at the thoracic spinal cord. The histopathologic examination confirmed cysticercosis. After treatment by albendazole and surgical removal, she still developed recurrent spinal compression at a higher level and obstructive hydrocephalus. Finally, she died from status epilepticus and septic shock.

Neurocysticercosis is the most common parasitic infestation of the central nervous system which manifests commonly as acute onset focal seizures. We report a rare clinical presentation of neurocysticercosis in a 1-year-old infant who presented with involuntary movements. Involuntary movements are not a common manifestation. Young children are rarely affected by this disease. In endemic areas, when a child presents with seizures or unusual neurological features and the CT scan shows contrast enhancing lesions or cystic lesions neurocysticercosis should be considered however young the child may be.

Cysticercosis is an infestation by Cysticercus cellulosae, the larval form of the cestode Taenia solium. C. cellulosae is preferentially encysted in the brain, striated muscles, and subcutaneous tissue. Seizures, hydrocephalus, meningitis, and focal symptoms caused by large cysts are the principal manifestations. Neuroophthalmologic signs are common with the meningitic and hydrocephalic manifestations of the disease. The first ophthalmologic clues of cysticercosis are typically papilloedema, pupillary abnormalities, or nystagmus. We report an atypical presentation of neurocysticercosis in two patients, with chief complaints of vertical diplopia and nystagmus.

This paper presents a case of a 28-year-old male with a seizure episode and a 4-year history of intermittent tinnitus on the left ear. On computed tomography and magnetic resonance imaging, a density with rim enhancement was found at the temporal lobe, associated with mastoid tegmen destruction and middle ear mass, indicating cholesteatoma with complicating brain abscess. Evacuation of the brain abscess was performed with a combined otolaryngologic and neurosurgical procedures (canal wall-down mastoidectomy and temporal craniotomy). The pathology turned out to be infestation with Echinococcus granulosus.
