case_images: Ultrasonography of the pelvis revealed a 5 x 4.3 cm, solid mass separated from her right adnexa (Fig. 1).
case_images: Contrast enhanced-CT shows a 5 x 4 cm solid, well-defined, heterogeneous mass in the right side of the pelvic cavity.

case_images: RJT122F2
case_images: Contrast enhanced-CT showed a 5 x 4 cm, solid, well-defined, heterogeneous mass in the right side of the pelvic cavity (Fig. 2).
case_images: MRI shows that the tumor is a homogeneous hypointensity on T1-weighted images (A) and a heterogeneous slight hyperintensity on T2-weighted images (B) in a right side of the pelvic cavity.

case_images: RJT122F3
case_images: MRI showed that the tumor demonstrated homogeneous hypointensity on T1-weighted images and heterogeneous slight hyperintensity on T2-weighted images (Fig. 3a and b).
case_images: Sagittal MRI sections show the mass to be intricately related to the anterior presacral fascia.

case_images: Sagittal sections of MRI demonstrated that the mass was intricately related to the anterior presacral fascia (Fig. 4).
case_images: Laparoscopic findings of schwannoma in the pelvis. 1, schwannoma 2, right ureter 3, rectum 4, right iliac vessel.

case_images: RJT122F5
case_images: With careful dissection using sharp and blunt maneuvers, the mass was dissected from the neighboring vessels, such as the right internal iliac vessels and ureter (Fig. 5).
case_images: The specimen is an elastic hard, 5 x 4 cm mass with an integral envelope. On sectioning, it is yellow and white in color, predominantly solid with cystic change.

case_images: RJT122F6
case_images: On sectioning, it was yellow and white in color, predominantly solid with cystic change (Fig. 6).
case_images: Histologic findings of schwannoma in the pelvis (hematoxylin and eosin, x200). (A) The Antoni A pattern is composed of spindle cells arranged in intersection fascicles. Nuclear palisades are seen and mitoses are rarely observed. (B) The Antoni B pattern is composed of loose hypocellular tissue.

case_images: RJT122F7
case_images: Pathologic examination showed whorls and interlacing fascicles of schwannoma spindle cells, along with alternating Antoni-A and -B patterns with areas of hyalinization and fibrinoid degeneration (Fig. 7a and b).
