R. Mittal","Sivashanmugam Dhandapani"],"abstract":"Background: Behavioral manifestations are a significant burden for patients with brain tumors. Cerebellar mutism syndrome, which can occur after posterior fossa surgery, is typically not associated with behavioral symptoms. This letter discusses a case of a 12-year-old boy who developed acute mutism and other behavioral issues following surgery for a posterior fossa mass lesion. Summary: The patient exhibited hyperactivity, inattention, and inappropriate social behavior after surgery. A single-photon emission computed tomography scan revealed cerebral hypoperfusion in the right frontal and thalamoganglionic regions. The findings suggest that altered speech and other symptoms following posterior fossa surgery may be linked to edema or hypoperfusion, indicating a more generalized impact on the brain than previously recognized. Conclusion: The presence of extensive remote hypoperfusion after posterior fossa surgery highlights the need for further investigation into atypical postoperative symptoms. Perfusion tests could provide valuable insights for evaluating these symptoms and may lead to new therapeutic and prognostic strategies.
