Extraabdominal desmoid tumor is a locally aggressive tumor despite being histologically benign. To avoid local recurrence, it is important to preoperatively detect the exact localization and extension of the infiltrating or disseminating lesion in this tumor. We report a case of recurrent extraabdominal desmoid tumor, which arose in the posterior thigh region, detected with Tl-201 (Tl) scintigraphy. In this case, Tl accumulated in the small disseminating lesion and to the recurrent tumor. This lesion was not identified by palpation because of its small size, deep localization and absence of symptoms, although MR imaging, which was performed after the Tl scintigraphy, clearly showed the lesion. After tumor resection, Tl did not accumulate in any region. These results suggest that Tl scintigraphy may be useful, not only for the diagnosis of extraabdominal desmoid tumor, but also for the detection of the exact localization or extension of small infiltrating or disseminating lesions before treatment.
腹壁外硬纤维瘤尽管在组织学上是良性的，但却是一种具有局部侵袭性的肿瘤。为避免局部复发，术前准确检测该肿瘤中浸润或播散性病变的精确位置和范围非常重要。我们报告一例复发性腹壁外硬纤维瘤病例，该肿瘤发生于大腿后部区域，通过铊-201（Tl）闪烁扫描得以检测。在该病例中，Tl在微小播散性病变及复发性肿瘤中聚集。由于该病变体积小、位置深且无症状，触诊未发现，但在Tl闪烁扫描后进行的磁共振成像（MR成像）清晰显示了该病变。肿瘤切除后，Tl未在任何区域聚集。这些结果表明，Tl闪烁扫描不仅可能有助于腹壁外硬纤维瘤的诊断，还可用于在治疗前检测微小浸润或播散性病变的精确位置或范围。
