Sinus pericranii is an unusual venous anomaly characterized by communication of pericranial varicosities with an underlying dural sinus. We report two cases of spontaneous partial thrombosis of sinus pericranii presenting as focally tender, nonreducible mass lesions different in character from the baseline venous abnormality. CT, CT angiography, and CT venography (CTV) were performed in both cases. CTV was essential in depicting thrombi within the varicosities. MR (in one case) demonstrated the anomaly well, but the thrombus was not evident. Conservative therapy was instituted in both cases.
颅骨膜窦是一种罕见的静脉异常，其特征是颅骨膜静脉曲张与深部硬脑膜窦相通。我们报告两例颅骨膜窦自发性部分血栓形成的病例，表现为局部压痛、不可复性肿块病变，其特征与基线静脉异常不同。两例均行CT、CT血管造影和CT静脉造影（CTV）检查。CTV对于显示静脉曲张内的血栓至关重要。磁共振成像（其中1例）很好地显示了该异常，但血栓不明显。两例均采取保守治疗。
