RESUMEN
BACKGROUND: Neurocysticercosis (NCC) is a global public health problem. It is a complex disease to manage and a cause of great morbidity and mortality in affected patients. Conventional surgical approaches have been used for many years, but currently, minimally invasive approaches are being used with good results. The authors present a case of NCC in the anterior interhemispheric fissure that was treated with a transventricular endoscopic approach. OBSERVATIONS: A 32-year-old male patient was admitted for persistent moderate headache and dizziness. Gadolinium-enhanced magnetic resonance imaging (MRI) showed multiple parenchymal, ventricular, and subarachnoid cystic lesions, especially in the anterior interhemispheric space. A transventricular endoscopic approach was selected and applied. There were no complications during surgery. Pathological analysis confirmed the diagnosis of NCC. Control MRI demonstrated the absence of cysts in the anterior interhemispheric space. LESSONS: Minimally invasive approaches are an excellent alternative for patients with NCC, especially if a patient requires more than one surgery.
RESUMEN
BACKGROUND: Neurocysticercosis, caused by the larval stage of Taenia solium, affects the cerebral ventricles in 20-30% of cases and may lead to hydrocephalus and other neurological morbidity. Conventional treatment for cysts in the 4th ventricle includes open surgery (suboccipital approach) and neuroendoscopy, with the latter being the option of choice. Stereotactic surgery, minimally invasive, offers a good alternative for this type of deep lesion. OBSERVATIONS: The authors report the cases of two women, 30 and 45 years old, who presented with headache, dizziness, and ataxia and were diagnosed with 4th ventricle cysticercosis. Magnetic resonance imaging (MRI) revealed dilated 4th ventricles (approximately 2.5 cm in both cases, with cystic images inside the ventricular cavity). Both patients were treated with stereotactic surgery via a suboccipital transcerebellar approach. Cyst material was extracted, and the diagnosis was confirmed by pathological examination. The surgeries had no complications and resulted in clinical improvement. Control MRI scans showed reduction of the volume of the ventricle without residual cysts. LESSONS: Minimally invasive stereotactic surgery provided a safe alternative for 4th ventricle neurocysticercosis cysts, with more benefits than risks in comparison with conventional techniques.
RESUMEN
BACKGROUND: Subarachnoid neurocysticercosis (NCC) is associated with high morbidity and mortality rates. Conventional transcranial approaches and transventricular endoscopy have been previously reported for extraparenchymal NCC and ventricular NCC, respectively. By October 2019, endonasal endoscopic approaches had not been used for the treatment of NCC. OBSERVATIONS: A 54-year-old-woman with NCC was admitted with acute neurological deterioration due to severe intracranial hypertension caused by massive subarachnoid NCC cysts, as evidenced on magnetic resonance imaging (MRI) with great brainstem compression. The case was discussed, and an endoscopic endonasal resection of the NCC cysts was scheduled. The diagnosis was confirmed by pathological anatomy. There were no complications in the surgery, with marked neurological improvement. Control MRIs demonstrated a significant reduction of NCC cysts. LESSONS: Minimally invasive approaches are an excellent alternative for skull-base tumoral and infectious pathology. Prior knowledge of the pathophysiology and the authors' experience in the management of patients with NCC allowed them to propose this approach, with optimal results.
