Phosphaturic mesenchymal tumor of the skull base presenting with tumor-induced osteomalacia and multiple fractures: a case report

Phosphaturic mesenchymal tumors include rare cranial base neoplasms that are often overlooked due to their nonspecific symptoms. Accurate diagnosis requires a comprehensive assessment, encompassing systemic evaluation, laboratory tests, imaging studies, and microscopic examination. This case demonstrates the innovative use of anlotinib capsules in the treatment of PMTs. After 2 years, no recurrence was observed, and the patient returned to normal life. Effective management of this condition necessitates a multidisciplinary approach involving otolaryngologists, radiologists, nuclear medicine specialists, and pathologists.
