Cerebral cysticercosis mimicking subarachnoid hemorrhage: a case report

Background Dense exudate during the calcification of cerebral cysticercosis in basal subarachnoid space was easy to be misdiagnosed as subarachnoid hemorrhage (SAH); clinical evaluation and MRI can help differentiate SAH from pseudo-SAH. Case presentation A case of ventricular expansion accompanied by high-density shadows in cisterna circinata cerebri was taken to the hospital for treatment due to sudden faint. This patient was diagnosed as subarachnoid hemorrhage according to computed tomography (CT) in another hospital. We believe that the high density in cisterna circinata cerebri was misdiagnosed as subarachnoid hemorrhage (SAH) 1 year ago. The main etiology of SAH is aneurysm; non-aneurysmal SAH associated with cerebral cysticercosis is extremely rare. Only 5 patients have been reported. Conclusion This case indicated that although the specificity of CT for SAH is very high, the physicians should be aware of rare false positive findings, called pseudo-SAH.

The rosette-forming glioneuronal tumor mimicked cerebral cysticercosis: a case report

Introduction Rosette-forming glioneuronal tumor (RGNT) is a rare variety of slow growing mixed glioneuronal tumor involving primarily fourth ventricular region. This is a comprehensive analysis of a 22-year-old woman with RGNT composed of mainly cystic components. In addition, the case showed multiple lesions located in brain parenchyma which mimicked cerebral cysticercosis. Here, we analyzed this case and listed some characteristics of RGNTs in reported literature which occurring in atypical locations for further understanding it. Case report A 22-year-old woman presented with a history of transient dizziness, nausea, and vomiting. Magnetic resonance imaging (MRI) showed multiple cystic lesions in brain parenchyma and then the patient was diagnosed with cerebral cysticercosis possibility. Empirical anti-infective therapy in addition to a follow-up post 2 weeks of MRI examination showed the lesions unchanged. Finally, a biopsy of the right cerebellar hemisphere lesions verified RGNT. Conclusion RGNT is an uncommon tumor classified as grade I glioma by World Health Organization (WHO) with slightly longer course. The imaging findings of RGNT are not specific especially in atypical areas. RGNT is rare, but we should also consider the possibility in diagnosis and differential diagnosis.

Cerebral Cysticercosis Masquerading as Eclampsia: A Case Report

Neurocysticercosis is a preventable parasitic disease of nervous system caused by Taenia solium. It may present with seizures, focal neurological deficits, decreased visual acuity and altered mental status. Eclampsia is a neurological manifestation of hypertensive disorders of pregnancy presenting as seizures. In common obstetric practice, all cases of unexplained seizures are managed as eclampsia unless proven otherwise. Neurocysticercosis presenting first time in pregnancy with seizures can be confused with eclampsia. The index case was referred to us in a similar manner in the second trimester of pregnancy with a diagnosis of eclampsia. Patient was evaluated further for the cause of seizures and was found to have neurocysticercosis on imaging. She was then conservatively managed and the pregnancy was continued till term rather than termination of pregnancy which is the standard management of eclampsia.
