To highlight challenges in interpreting negative MR spectroscopy results in hemorrhagic neoplasms and timing of resection.
Presented an illustrative case of primary intracranial sarcoma with DICER-1 mutation.
Evaluated MR spectroscopy results
Assessed resection timing concerning spontaneous intracerebral hemorrhage (IPH).
Negative MR spectroscopy did not provide clear diagnostics for the intracranial tumor.
Challenges were identified in determining the optimal resection timing for the patient.

Resumen

This case demonstrates the need to interpret negative MR spectroscopy results with caution in cases of hemorrhagic neoplasms. Furthermore, it highlights the difficulty when determining optimal resection timing in cases of spontaneous IPH without a clear etiology. https://thejns.org/doi/10.3171/CASE25899.
