case_images: Head computed tomography images from a 58-year-old male patient with lower
  limb weakness and a mass in the right frontoparietal lobe, right lateral
  ventricle, showing the solid part of the tumour (red arrows), the cystic
  part of the tumour (white arrows), and calcification (black arrows).

case_images: fig1-03000605221148146
case_images: A head computed tomography (CT) scan (Figure 1) revealed a mass in the right frontoparietal lobe, right lateral ventricle.
case_images: Magnetic resonance images from a 58-year-old male patient with lower limb
  weakness and a mass in the right frontoparietal lobe, right lateral
  ventricle, showing: (a) T1-weighted images; (b) T2-weighted images; (c)
  fluid-attenuated inversion recovery images; (d) diffusion-weighted images;
  and (e) enhanced T1-weighted images.

case_images: fig2-03000605221148146
case_images: The MRI showed an irregular tumour signal (Figure 2).
case_images: Results of magnetic resonance spectroscopy in a 58-year-old male patient with
  lower limb weakness and a mass in the right frontoparietal lobe, right
  lateral ventricle. The choline (Cho), N-acetyl-aspartate (NAA), and lactate
  (Lac) peaks supported a diagnosis of glioma.

case_images: fig3-03000605221148146
case_images: During magnetic resonance spectroscopy (MRS) imaging, the N-acetyl-aspartate (NAA) peak was low, the choline (Cho) peak was elevated, and the NAA/Cho ratio was 2.0 (Figure 3).
case_images: Intraoperative tumour images from a 58-year-old male patient with lower limb
  weakness and a mass in the right frontoparietal lobe, right lateral
  ventricle, showing: (a) capsule contents (red arrows); and (b) the solid
  tumour (white arrows).

case_images: fig4-03000605221148146
case_images: The solid part of the tumour was grey-white and tough, with unclear boundary that was poorly differentiated from the brain tissue and rich in blood supply (Figure 4), which were features typical of epidermoid cysts.
case_images: Postoperative pathology showing haematoxylin and eosin-stained tumour tissue
  sections from a 58-year-old male patient with lower limb weakness and a mass
  in the right frontoparietal lobe, right lateral ventricle, confirming
  malignant squamous cell carcinoma.

case_images: fig5-03000605221148146
case_images: Postoperative pathology confirmed that the epidermoid cyst had transformed into malignant squamous cell carcinoma (Figure 5).
