Phyllodes tumors (PTs) are rare breast tumors characterized by varying biological behavior and heterogeneous clinical findings. As a result, accurately diagnosing PTs preoperatively is challenging, often leading to misdiagnosis. A 49-year-old patient presented with a steadily growing right breast mass that had persisted over a 10-year period. Breast mammography and ultrasonography results indicated the presence of a PT. Following a lumpectomy, the patient was diagnosed with a borderline PT. However, nearly 1 year later, she was readmitted due to the recurrence of a palpable mass at the site. Consequently, 1 year and 8 months after the initial operation, she underwent thoracoscopic lobectomy to address solitary lung metastases. Subsequently, the patient experienced brain metastasis and massive hemorrhage 14 months later. Long-term follow-up was recommended. This case study presents an instance of borderline PT with clinical and imaging features that are crucial for guiding clinical operations and evaluating patient prognosis.

乳腺叶状肿瘤的临床和放射学评估：病例报告。


叶状肿瘤（PT）是罕见的乳腺肿瘤，其特征是不同的生物学行为和异质的临床表现。因此，术前准确诊断 PT 具有挑战性，常常导致误诊。一名 49 岁的患者因右乳肿块持续增大而就诊，该肿块已持续 10 年之久。乳房 X 光检查和超声检查结果表明存在 PT。肿瘤切除术后，患者被诊断为临界 PT。然而，近一年后，由于该部位再次触及肿块，她再次入院。因此，在初次手术后 1 年零 8 个月，她接受了胸腔镜肺叶切除术以解决孤立性肺转移问题。随后，14个月后，患者出现脑转移和大出血。建议进行长期随访。本案例研究介绍了一个边缘性 PT 的实例，其临床和影像学特征对于指导临床操作和评估患者预后至关重要。
