case_images: (a) Transvaginal ultrasound of the right ovary in grayscale view demonstrates the morphological features of the polycystic ovarian disease: Hyperechoic central stroma, peripheral location of follicles (a string of pearls sign), follicles of similar size measuring 2-9 mm, and increased right ovary size and volume; the right ovary measures approximately 40 mm x 22 mm x 24 mm (length x width x thickness) (corresponding to a volume of 11.65 cm3). An ovary typically weighs 2-8 g. However, they change during life and double in size during pregnancy. (b) Transvaginal ultrasound of the right ovary in color Doppler study demonstrates the mean spectral of the ovarian stromal arteries. However, using color Doppler transvaginal ultrasonography in the clinical diagnosis of patients with polycystic ovary syndrome is not beneficial.

case_images: Subsequent investigation revealed that the patient initially presented with chronic headaches and oligomenorrhea, which led to the diagnosis of polycystic ovarian syndrome (PCOS) years before her initial diagnosis of PTC [Figures 1 and 2].
case_images: (a) Transvaginal ultrasound of the left ovary in grayscale view demonstrates the morphological features of polycystic ovarian disease: Hyperechoic central stroma, peripheral location of follicles (a string of pearls sign), follicles of similar size measuring 2-9 mm, and increased left ovary size and volume; the left ovary measures approximately 34 mm x 19 mm x 33 mm (length x width x thickness) (corresponding to a volume of 11.73 cm3). An ovary typically weighs 2-8 g. However, they change during life and double in size during pregnancy, (b) transvaginal ultrasound of the left ovary in color Doppler study demonstrates the mean spectral of the ovarian stromal arteries. However, using color Doppler transvaginal ultrasonography in the clinical diagnosis of patients with polycystic ovary syndrome is not beneficial.

case_images: (a) Brain computed tomography scan in two axial planes without contrast demonstrates an empty sella (white arrows) filled with cerebrospinal fluid (CSF) without visualization of the pituitary gland. (b) The sella is empty and enlarged. The sella contains fluid of CSF density.

case_images: CT scan findings showed a 3 x 5 mm fat density structure in the third ventricular roof region beneath the body of the corpus callosum and an empty appearance of the sella turcica [Figure 3].
