Résumé

Pituitary adenomas (PA) are usually benign neoplasms. Chiari I malformation (CIM) is an uncommon finding. Isolated cases associating functional PA and CIM have been reported. The concomitant presence of a nonfunctional PA and a CIM has not yet been described in the literature. We present the case of a 35-year-old patient whose symptoms were compatible with CIM. Magnetic resonance imaging of the brain, with and without contrast material, confirmed the CIM and incidentally encountered a PA. The patient was treated initially for her PA through an endoscopic endonasal approach with complete tumor resection, confirming a nonfunctional PA. Posterior fossa decompression was successfully accomplished 3 months later. The patient has been followed up for 5 years and has been free of symptoms, with no recurrence of her PA. This represents the first reported case of a nonfunctional PA with a concomitant CIM. This is the first reported case of a concomitant CIM and a nonfunctional PA. We discuss our successful management and conduct a systematic review of the literature to provide the most up-to-date guidance on managing these singular cases with concomitant pathologic conditions.

BACKGROUND BACKGROUND
Pituitary adenomas (PA) are usually benign neoplasms. Chiari I malformation (CIM) is an uncommon finding. Isolated cases associating functional PA and CIM have been reported. The concomitant presence of a nonfunctional PA and a CIM has not yet been described in the literature.
CASE DESCRIPTION METHODS
We present the case of a 35-year-old patient whose symptoms were compatible with CIM. Magnetic resonance imaging of the brain, with and without contrast material, confirmed the CIM and incidentally encountered a PA. The patient was treated initially for her PA through an endoscopic endonasal approach with complete tumor resection, confirming a nonfunctional PA. Posterior fossa decompression was successfully accomplished 3 months later. The patient has been followed up for 5 years and has been free of symptoms, with no recurrence of her PA. This represents the first reported case of a nonfunctional PA with a concomitant CIM.
CONCLUSION CONCLUSIONS
This is the first reported case of a concomitant CIM and a nonfunctional PA. We discuss our successful management and conduct a systematic review of the literature to provide the most up-to-date guidance on managing these singular cases with concomitant pathologic conditions.
