A 9-year-old domestic short hair cat presented with a firm thoracic mass suspected to be a lipoma. Preoperative indocyanine green was administered intravenously at a dose of 5 mg/kg for short-wave infrared fluorescence imaging. Intraoperatively, a plaque-like lipoma overlaid a subjacent mass that exhibited strong fluorescence. Both were excised, and histopathology confirmed the subjacent mass as a well-differentiated liposarcoma. The cat recovered uneventfully with no recurrence at 11 months. This case highlights the utility of short-wave infrared fluorescence imaging in distinguishing benign from malignant tissues intraoperatively and enabling precise resection. To our knowledge, this is the first report of feline liposarcoma identified through short-wave infrared fluorescence imaging, demonstrating its potential as a valuable tool in veterinary oncology.
一只9岁的家养短毛猫出现一个坚硬的胸部肿块，怀疑是脂肪瘤。术前静脉注射吲哚菁绿，剂量为5mg/kg，用于短波红外荧光成像。术中，一个斑块状脂肪瘤覆盖在下方一个发出强烈荧光的肿块上。两者均被切除，组织病理学证实下方肿块为高分化脂肪肉瘤。这只猫术后恢复顺利，11个月时无复发。该病例突出了短波红外荧光成像在术中区分良性和恶性组织以及实现精确切除方面的实用性。据我们所知，这是通过短波红外荧光成像识别猫脂肪肉瘤的首例报告，证明了其作为兽医肿瘤学中有价值工具的潜力。
