摘要
The authors reported the case of a 35-year-old woman with an unusual huge recurrent meningioma in the left cerebral hemisphere confirmed by the pathological examination.This patient's clinical presentation was very unusual.Brain magnetic resonance imaging(MRI) demonstrated a huge tumor in the left frontal region.The extracranial surface dimensions of the mass were 12cm craniocaudal × 11cm transverse × 9cm anteroposterior;and the intracranial dimensions were 9cm craniocaudal × 7cm transverse × 10cm anteroposterior respectively.The patient underwent left frontal recurrent meningioma resection by microsurgery,with total tumor resection.Following which the patient was discharged in a stable condition.To the best of the authors' knowledge,such an unusual huge recurrent meningioma has not been reported.The authors reviewed the literatures with reference to recurrent meningioma,analyzed the unusual imaging appearances of this patient,and explored the mechanism underlying the huge volume formation.The fundamental principle to reducing or completely avoiding meningioma recurrence is to achieve total tumour resection.Recurrent meningiomas are also amenable to surgery.
