Anatomical variations are common in gluteal region. This report presents two cases of gluteoperinealis muscles detected during radiological imaging.
Our study was conducted on two patients. This report describes an accessory muscle detected in the gluteal region on MRI examination of a patient who admitted to our clinic after a firearm injury and a second patient examined with CT imaging who had signs of pelvic infection. In the first case, this accessory muscle originated bilaterally from the fascia of the gluteus maximus throughout its posteromedial side and was attached to the perineal body. In the second case, it extended forward from the fascia of the gluteus maximus muscle and inserted to the cavernous body of penis on the left side and to the perineal body on the right. In the literature, this accessory muscle has been described as the gluteoperinealis muscle being a rare variation.
Considering the origin and insertion of the muscle, this variation may be important during the surgical operations of the gluteal and perineal regions.
臀部区域常见解剖变异。本报告介绍了在影像学检查中发现的两块臀小肌的病例。
我们的研究对象为两名患者。本报告描述了一名患者在因枪伤就诊于我院时 MRI 检查中发现的一块附加肌肉，以及另一名患者 CT 检查时发现的有骨盆感染迹象的患者。在第一个病例中，这块附加肌肉从臀大肌筋膜双侧起始，沿其后内侧延伸，并附着于会阴体。在第二个病例中，它从臀大肌筋膜向前延伸，左侧插入阴茎海绵体，右侧插入会阴体。在文献中，这块附加肌肉被描述为臀小肌，是一种罕见的变异。
考虑到肌肉的起点和止点，这种变异在臀部和会阴区域的手术操作中可能很重要。
