It is difficult for convexity arachnoid cysts to determine where the cyst should be fenestrated because there is no large cistern around the cyst. We successfully fenestrated a recurrent convexity arachnoid cyst during a second surgery because of the information provided by preoperative fast imaging employing steady-state acquisition (FIESTA) magnetic resonance (MR) imaging. A 19-year-old woman experienced a progressive headache and was diagnosed with an arachnoid cyst in the right temporal lobe, for which she underwent membranectomy. However, the cyst was gradually enlarging for 2 years after the first surgery and the patient’s headache recurred. FIESTA MR images revealed the membrane between the cyst and the distal sylvian fissure. This membrane was dissected and resected to connect to the cistern in the second surgery.
