Different aspects of hepatosplenic schistosomiasis are revisited here. Manson's schistosomiasis causes periportal fi brosis and portal hypertension in approximately 6% of infected subjects, usually with preservation of their hepatic function. The assessment of liver involvement is of major importance in determining the prognosis and risk of complications from schistosomiasis, such as upper digestive bleeding secondary to variceal rupture. For many years, the diagnosis of hepatosplenic schistosomiasis and liver fi brosis was made by abdominal palpation and the fi nding of liver and/or spleen enlargement. However, there is no consensus regarding the clinical parameters of the liver and spleen to be considered in this physical evaluation. For the last three decades, abdominal ultrasound (US) has become the best imaging technique to evaluate liver fi brosis caused by schistosomiasis mansoni. However, US is a subjective procedure and is therefore examiner-dependent. Magnetic resonance imaging (MRI) fi ndings have provided valuable information in addition to ultrasound and clinical examination. The combination of a comprehensive history and physical examination, basic laboratory tests (a stool examination for Schistosoma mansoni eggs and a blood cell count), biomarkers for liver fi brosis/portal hypertension and imaging methods seem to offer the best approach for evaluating patients with this disease. In situations where research is involved or in patients with severe disease, MRI may be considered.

“…In some reported cases of neuroschistosomiasis, brain tumors, such as meningioma and glioma, had been suspected initially (2,13,23). Moreover, as in the present case, patients with cerebral schistosomiasis may have no clinical evidence of systemic disease (21,28).…”

Cerebral Schistosomiasis Due to Schistosoma haematobium Confirmed by PCR Analysis of Brain Specimen

The case of a 25-year-old Japanese male who had cerebral schistosomiasis caused by Schistosoma haematobium is reported here. Although serum antibody tests showed a cross-reaction with other helminths and no ova were excreted in urine or feces, the existence of Schistosoma haematobium in the brain was confirmed by PCR analysis. CASE REPORTIn October 2009, a 25-year-old Japanese man was admitted to a local community hospital in Japan with a 1-week history of mild headache and sporadic paraphasia. He had worked as an agricultural consultant in the Republic of Malawi from April 2007 to June 2009. During his stay, he lived with local residents, consumed water from a well, and had swum in a lake at least twice. He had been in excellent health until October 2009, except for a Giardia lamblia infection in 2008. At the community hospital, a computed tomography (CT) scan of the patient's head showed four hyperdense and edematous lesions in the left parietal lobe, and these lesions were suspected to be related to tropical infectious diseases due to the fact that the onset of his symptoms appeared soon after his return from the Republic of Malawi. Subsequently, the patient was referred to our institution for further workup.Upon presentation to our institute, the patient's temperature was 36.8°C, his pulse was 60 beats per minute (bpm), and his blood pressure was 120/70 mm Hg. Although the patient was alert and appropriate at a glance, verbal paraphasia was occasionally observed. Laboratory evaluation revealed the following: white blood cell count, 8,780/l (67.5% neutrophils, 25.0% lymphocytes, 1.5% eosinophils); serum C-reactive protein, 0.03 mg/dl; IgE, 18 U/ml; HIV antibody negative; toxoplasma IgM and IgG negative; and Entamoeba antibody negative. A magnetic resonance imaging (MRI) scan of the brain with gadolinium enhancement showed a couple of ill-defined, heterogeneously enhancing lesions. They were each approximately 10 mm in diameter, in the left parietal lobe, with increased intensity of the signal on the T1-weighted image (Fig. 1). A lumbar puncture was not performed. The patient's headache and nausea worsened rapidly, and we were obliged to relieve his symptoms as soon as possible. Based on the clinical presentation and characteristic imaging finding, we clinically concluded that the cerebral lesions were neurocysticercosis. Albendazole (15 mg/kg of body weight per day) was administered with dexamethasone (0.1 mg/kg per day) for a total of 8 days. The patient's headache and nausea then subsided, and the verbal paraphasia disappeared. The findings from an MRI scan of the brain were improved but still remained.One week after the initiation of treatment, the results of the commercially available serum enzyme-linked immunosorbent assay (ELISA; SRL, Tokyo, Japan), which can detect IgG antibody for 12 helminthic diseases as a screening (22), were reported: Spirometra erinacei (also known as Spirometra mansoni) antibody on admission was positive, whereas Taenia solium antibody was negative. Schistosoma species are not ...
