case_images: Transvaginal ultrasound and Doppler ultrasound imaging of an ovarian fibroma (our case) . A solid hypoechoic mass with clear margins and minimal Doppler flow signals (red arrow) are typical ultrasound features of ovarian fibroma

case_images: FIG1
case_images: Transvaginal ultrasound showed a solid, discrete, echogenic mass occupying the anatomic position of the right ovary, with no space-occupying lesion from the uterine corpus (Figure 1).
case_images: MRI of ovarian fibroma (our case) . In the anatomical position of the right adnexa (red arrows) the presence of a pathologic space-occupying lesion that occupies the ipsilateral ovary is highlighted, without the presence of imaging of normal ovarian tissue

case_images: FIG2
case_images: In the anatomical location of the right ovary, the presence of a multilobular pathological space-occupying mass of low signal intensity was found on T2 sequences, with estimated size of 41x35x42 mm (Figure 2).
case_images: Surgical specimen of ovarian fibroma (our case) . The presence of an insignificant area of healthy ovarian tissue (yellow arrows) is characteristic, which led to the decision to surgically resect the fibroma along with the ovary and resect the ipsilateral fallopian tube

case_images: FIG3
case_images: The estimated technical surgical difficulties when attempting to exclude the tumor, the increased risk of recurrence and the increased possibility of remaining non-functional ovarian tissue postoperatively led to the decision to remove the ovarian mass along with the ovary (Figure 3) and to remove the ipsilateral fallopian tube at the same time.
case_images: Histological image of ovarian fibroma (our case) . A predominantly fascicular pattern of  development of spindle-shaped cells with eosinophilic cytoplasm emerges

case_images: Histopathological examination of the surgical specimen confirmed the diagnosis of ovarian fibroma, approximately 45mm in maximum diameter, with mild cellularity and absence of atypia and multiple mitoses (Figures 4, 5).
case_images: Histological image of ovarian fibroma (our case) . On magnification, collagen deposition and mitosis are recognized
