Patient
male, 55 year(s)
 
 
  • Figure 1
    Axial CT scans
     

    Axial CT scan showed hernia of mesenteric fat tissue. Retroperitoneal well-shaped homogeneus unenhancing hypodense masses (plexiform neurofibromas) were notted. Right psoas neurofibroma was seen as hypoattenuating mass.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    Subcutaneous multilobulated neurofibromas were observed by CT scan. Left psoas muscle and left anterior abdominal wall were not seen due to surgery the patient underwent.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;
     
     
  • Figure 2
    Axial CT scans
     

    Contrast-enhanced CT scans revealed pararectal, subcutaneous hypodnese masses. Some of the lesions were enhancing mildly. And some of multilobulated lesions had clacifications.

  • Figure 3
    T2 weighted and unenhanced T1 weighted axial images
     

    Pararectal and pelvic neurofibromas were oval-shaped and multilobulated. Masses were hypointense-isointense in T1 weighted images, heterogenous hyperintense in T2 weighted images.

     
    Area of Interest: Abdomen; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Congenital;

    Pararectal and pelvic neurofibromas were oval-shaped and multilobulated. Masses were hypointense-isointense in T1 weighted images, heterogenous hyperintense in T2 weighted images.

  • Figure 4
    Contrast enhanced T1 weighted axial images
     

    MRI showed pelvic and inguinal target-like lesions. Pararectal oval, midly heterogenous, hypointense neurofibromas were demonstrated.

    Coronal T2 wighted images
     

    T2 weighted coronal image revealed subcutaneus target-like neurofibromas.

    T2 weighted coronal image revealed paraspinal neurofibromas.
