Sinus pericranii is a @entity5 of the head having communication with the dural venous system. The @entity5 enlarges with @entity428 when the @entity1 is in the lateral recumbent position. Since Stromeyer used the term "sinus pericranii" in his report in 1850, approximately 170 cases have been reported. However, relatively few cases of sinus pericranii have been reported in association with @entity91 or by plastic surgeons. In this study, we report seven cases of sinus pericranii associated with @entity91 . There were two @entity1 with @entity4886 , two with @entity2168 , two with @entity91 , and one with @entity91 . The sites of occurrence were the parietal region in six @entity1 and the frontal region in one @entity1 . In either type of case, the @entity5 was clinically a soft subcutaneous mass of the head. The clinical characteristics of the @entity5 were its disappearance when the @entity1 was in a sitting position and its appearance when the @entity1 was in a recumbent position or crying. The @entity1 were preoperatively diagnosed with sinus pericranii from imaging test findings, such as from magnetic resonance imaging and aforementioned clinical findings. In all cases, treatment for sinus pericranii was performed during the surgery for @entity91 . For @entity1 with lesions in either site, we did not perform craniotomy, and we used a minimally invasive method of @entity5 excision and resection of the sites of communication using electrocoagulation. Perioperatively, heavy @entity548 was not observed, and, postoperatively, no recurrence has been observed in any @entity1 . In this study, we examine the etiology, diagnosis, and treatment of sinus pericranii, in particular for @entity1 with @entity91 .
