Spontaneous Resolution of Postoperative Giant Frontal Pseudomeningocele

Cranial pseudomeningoceles are abnormal extradural collections of cerebrospinal fluid. Postoperative giant cranial pseudomeningoceles have been rarely reported in the literature and have no specific treatment guidelines. The optimal management strategy for this condition differs among authors, varying from conservative approach to surgical intervention. A spontaneous resolution of postoperative giant frontal pseudomeningocele is reported. A 41-year-old female presented a pseudomeningocele 3 weeks after a right frontal meningioma surgical resection. The pseudomeningocele progressed during the first 1.5-month postoperatively despite percutaneous aspiration and compressive bandage, it then shrank spontaneously and was completely resolved at the 15(th) month since the surgery. Nonoperative treatment with a close follow-up could be a good option for asymptomatic giant pseudomeningoceles, resulting in a spontaneous resolution.
