Inflammatorischer Pseudotumor der Harnblase
Multidetector
computed tomography evaluation of bladder lesions. A 40-year-old male patient with an inflammatory myoblastic tumor of the bladder. Axial pre-contrast (a) and post-contrast (b) CT images showing a single poorly marginated intraluminal polypoid mass with avid ring enhancement (arrow)
Unusual cause
of urinary retention in a child: inflammatory pseudotumor of the urinary bladder. Transverse grayscale ultrasound (a) and color Doppler (b) image through the pelvis show well-marginated hypoechoic mass lesion (arrow in a and b) arising from the bladder neck projecting into the bladder lumen. The lesion shows mild vascularity
Unusual cause
of urinary retention in a child: inflammatory pseudotumor of the urinary bladder. Sagittal T1W image (a), T2W coronal image (b), and T2W FS axial image through the pelvis show polypoidal lesion arising from the bladder base (arrow in a, b, and c). The lesion is hypo- to isointense on T1W and mildly hyperintense on T2W with no suppression on fat-suppressed images. Patchy areas of diffusion restriction are seen (arrow in d)

inflammatorischer Pseudotumor Radiopaedia • CC-by-nc-sa 3.0 • de
Inflammatory myofibroblastic tumors (IMT), also known as plasma cell granulomas, are rare neoplasms that have a diverse spectrum of biological behavior.
Terminology
These tumors were previously referred to as inflammatory pseudotumor.
Epidemiology
They can occur at any age and there is currently no recognized gender predilection.
Pathology
Composed of spindle cells (key feature) with a variable infiltrate of inflammatory cells and fibrous tissue. They can occur at numerous sites:
- more common
- lung: inflammatory myofibroblastic tumor of the lung
- abdominal cavity
- retroperitoneum
- extremities
- less common
- liver
- spleen
- genitourinary tract
Radiographic features
Imaging characteristics depend on the organ of involvement:
