Abstract:
Spontaneous meningiomas are rarely reported in nonhuman primates, and among the documented cases, only a few are thoroughly characterized. This report describes a case of atypical meningioma in a pregnant rhesus macaque (Macaca mulatta) that exhibits pathobiological features that mirror humans.
Insights
A rare atypical meningioma was found in a pregnant rhesus macaque. This case offers valuable insights into meningiomas, which share similar pathobiological features with human cases.
Area of Science:
- Comparative pathology
- Primate oncology
- Neuro-oncology
Background:
- Spontaneous meningiomas are uncommon in nonhuman primates.
- Thorough characterization of these tumors in primates is infrequent.
- Understanding meningiomas in animal models can inform human research.
