AbstractLarge cystic craniopharyngiomas can be treated with chemotherapy injected directly into the cyst. Chemotherapy is toxic if it leaks from the cyst into the subarachnoid space. We present a child with a cystic craniopharyngioma following surgical placement of a catheter into the cystic component. Computed tomography following iodinated contrast injection into the cyst was inconclusive in determining the cyst wall integrity. Magnetic resonance following dilute gadopentetate dimeglumine injection into the cyst clearly defined a leak into the subarachnoid space. Coronal imaging was especially helpful. This technique is simple to perform and useful for clinical management.
