RESUMO
PURPOSE: To illustrate the value of cross-sectional imaging (CT, MRI) for the diagnosis and follow-up of intracranial hydatid cysts in children. MATERIALS AND METHODS: Retrospective study of 9 cases of intracranial hydatid cysts in children seen over a period of 8 years. Precontrast and postcontrast 5 mm thick axial CT images were obtained in 7 cases. Noncontrast sagittal, axial and coronal T1W and T2W images were obtained in 2 cases. RESULTS: Mean patient age was 7.5 years. Intracranial hypertension was the main presenting clinical symptom. A single supratentorial cyst with significant mass effect upon the ventricular system and midline structures was observed in all cases. All patients underwent surgery with good outcome in all cases. CONCLUSION: CT is the imaging modality of choice for diagnosis and postoperative follow-up of intracranial hydatid cysts in children. MRI is most helpful for further characterization when multiple or atypical cysts are present to optimize management.
