Hydatidosis occurs due to infestation with the larval stage of the Echinococcus species. Humans are incidental hosts. Symptoms and signs in humans are a slowly growing mass lesion, especially in the central nervous system. Diagnosis depends on the appropriate presentation and history with corroborative radiology and serology. Microscopic detection of characteristic parasitic scolices and hooklets is confirmatory.
A 10-year-old girl presented with complaints of headaches and convulsions for the preceding several months. Computed tomography findings showed asymmetric dilatation of the right lateral ventricle by an intraventricular, focally calcified mass. The radiologic suspicion was an intraventricular tuberculoma, hydatid cyst or choroid plexus papilloma. Cytologic examination of cerebrospinal fluid (CSF) smears revealed characteristic echinococcal components.
Intracranial hydatid cyst is a fairly uncommon manifestation of an echinococcal infestation and shares clinicoradiologic features with several intracranial, space-occupying lesions. Cytologic examination of CSF samples may be employed to detect confirmatory evidence of a clinical/radiologic suspicion.
包虫病是由棘球绦虫幼虫阶段感染所致。人类为偶然宿主。人类的症状和体征为缓慢生长的肿块病变，尤其是在中枢神经系统。诊断取决于合适的临床表现和病史，以及辅助性的放射学和血清学检查。显微镜下检测到特征性的寄生虫头节和小钩可确诊。
一名10岁女孩在之前几个月出现头痛和惊厥症状。计算机断层扫描结果显示，脑室内一个局灶性钙化肿块导致右侧脑室不对称扩张。放射学怀疑为脑室内结核瘤、包虫囊肿或脉络丛乳头状瘤。脑脊液涂片的细胞学检查发现了特征性的棘球绦虫成分。
颅内包虫囊肿是棘球绦虫感染相当罕见的表现，与几种颅内占位性病变具有临床放射学特征。脑脊液样本的细胞学检查可用于检测临床/放射学怀疑的确诊证据。
