Abstract
INTRODUCTION
Chordoma is a malignant and aggressive tumor originating from remnants of the primitive notochord and usually involving the axial skeleton. Spontaneous regression of clival chordomas was described recently. We present the third case report of spontaneous regression of a clival chordoma and discuss similarities of cases and implications for clinical practice.
CASE DESCRIPTION
We present the case of a previously healthy 21-year-old Caucasian woman who presented with progressive holocranial headache for 3 months, which encouraged image investigation. Magnetic resonance imaging (MRI) revealed an osteolytic clival lesion hyperintense in T2 and hypointense in T1 images. After 2 months of initial evaluation and surgical proposal, she repeated MRI to allow use for intraoperative neuronavigation. Surprisingly, there was tumor regression.
DISCUSSION
The present reported case is somehow different from previous ones and does not share an underlying inflammatory/immunological recognizable fact, being interpreted by us as a spontaneous partial regression of the tumor. We highlight the need for continuous investigation of chordoma regression to uncover the underlying mechanisms.
