8 Couldwell, William T.; MacDonald, Joel D.Surgical strategies for recurrent craniofacial meningiomasRecurrent cranial base meningiomas are among the most difficult tumors to treat surgically.

13 Couldwell, William T.Recurrent infrasellar clival craniopharyngiomaThe patient is a 44-year-old man who underwent resection of a posterior nasopharynx tumor 12 years earlier via left lateral rhinotomy approach.
