Primay melanoma of the cavernous sinus is very rare with only few cases reported in the literature. We present the cross-sectional imaging findings of this rare tumor. The differential diagnosis for cavernous sinus mass lesion is wide as it contains vital neurovascular structures that may be affected by vascular, neoplastic, infective, and infiltrative lesions arising in the cavernous sinus proper or via extension from adjacent intra and/or extracranial regions. Radiologic imaging can narrow the differential diagnosis, however, imaging cannot definitely reach single diagnosis if they present in atypical form with hemorrage and cystic degeneration. This case report illustrates that primary cavernous sinus melanoma may present as a atypical tumor with diagnostic dilemma.
海绵窦原发性黑色素瘤非常罕见，文献中仅有少数病例报道。我们展示了这种罕见肿瘤的横断面影像学表现。海绵窦肿块病变的鉴别诊断范围很广，因为它包含重要的神经血管结构，这些结构可能受到海绵窦本身或从相邻的颅内和/或颅外区域延伸而来的血管、肿瘤、感染和浸润性病变的影响。放射学成像可以缩小鉴别诊断范围，然而，如果它们以伴有出血和囊性变的非典型形式出现，成像不能明确得出单一诊断。本病例报告表明，原发性海绵窦黑色素瘤可能表现为具有诊断困境的非典型肿瘤。
