Abstract

Case summary: A 13-year-old castrated male American Shorthair cat was referred for evaluation following a 3-week history of poor balance and decreased activity. The MRI findings revealed a well-defined left caudal cerebellar mass with a diameter of 1.2 cm, consistent with a meningioma. CT and MRI scans did not reveal metastasis. After a suboccipital craniotomy, the mass was resected subtotally as a result of parenchymal invasion. A histopathological examination revealed a benign fibrous meningioma with invasion into the cerebellum at the tumour margins. Postoperatively, the cat remained asymptomatic for 25 months, but ataxia recurred, and tumour recurrence was confirmed using MRI and post-mortem examination.

Relevance and novel information: This case demonstrates that even feline meningiomas with benign features can exhibit brain invasion. Since brain invasion is an indicator of malignancy in meningioma, a detailed histopathological evaluation of the tumour margins is essential for accurate grading and prognosis.

猫脑内良性脑膜瘤的侵袭。
病例总结:一只13岁的阉割雄性美国短毛猫在3周的平衡不良和活动减少史后被转介进行评估。MRI显示左侧小脑尾端有一直径1.2 cm的清晰肿块,符合脑膜瘤。CT和MRI扫描未发现转移。在枕下开颅手术后,肿块因实质侵犯而被部分切除。组织病理学检查显示良性纤维脑膜瘤,肿瘤边缘浸润小脑。术后25个月,猫无症状,但共济失调复发,并通过MRI和尸检确认肿瘤复发。相关和新信息:本病例表明,即使是具有良性特征的猫脑膜瘤也可能表现为脑侵犯。由于脑浸润是脑膜瘤恶性的一个指标,因此对肿瘤边缘进行详细的组织病理学评估对于准确的分级和预后至关重要。
