Abstract

The infratemporal fossa is a deep anatomical space rarely involved in lymphoproliferative disorders. Small lymphocytic lymphoma (SLL), a low-grade subtype of non-Hodgkin lymphoma (NHL), is exceptionally rare in this region, with only a few cases reported in the literature. We report the first known case of a 48-year-old patient with a primary, bilateral, butterfly-shaped SLL of the infratemporal fossae, discovered incidentally during imaging after a road traffic accident. Clinical signs of infratemporal fossa involvement are often nonspecific or absent, particularly in indolent forms like SLL. Diagnosis relies on imaging, histopathology, and immunohistochemistry. Treatment typically involves chemotherapy, especially purine analogues, while surgery is usually limited to diagnostic biopsy. Long-term follow-up with laboratory and radiologic monitoring is essential due to the risk of recurrence or systemic involvement, including the spleen, liver, and lymph nodes.

蝴蝶影像：一个罕见的双侧颞下窝原发性小淋巴细胞淋巴瘤的偶然发现

颞下窝是一个深解剖空间，很少涉及淋巴细胞增生性疾病。小淋巴细胞淋巴瘤（Small lymphocytic lymphoma， SLL）是非霍奇金淋巴瘤（non-Hodgkin lymphoma， NHL）的一种低级别亚型，在该地区极为罕见，文献中仅有少数病例报道。我们报告第一例已知的48岁患者的原发性，双侧，蝶状颞下窝SLL，偶然发现在一次道路交通事故后的影像学检查。颞下窝受累的临床症状通常是非特异性的或不存在的，特别是在像SLL这样的惰性形式。诊断依赖于影像学、组织病理学和免疫组织化学。治疗通常包括化疗，特别是嘌呤类似物，而手术通常仅限于诊断活检。由于有复发或全身受累（包括脾、肝和淋巴结）的风险，实验室和放射学监测的长期随访是必要的。
