Recurrence of Cystic Part of Cerebellar Hemangioblastoma at Early Postoperative Period and its Spontaneous Resolution: A Pregnant Patient With Serial Magnetic Resonance Imaging Findings

We report a patient with cerebellar hemangioblastoma who was operated during her seventh month of pregnancy. The patient underwent operation during which the mural nodule was removed and cyst aspirated but the cyst wall was not. At 17th day after operation, the cystic part of the mass recurred. She was not reoperated and a conservative approach was adopted. During follow-up, magnetic resonance imaging showed spontaneous resolution of the cerebellar cystic lesion. The mechanism for recurrence and spontaneous resolution of the cystic part of the tumor is discussed.
