FIG1
A non-contrast computed tomography (NCCT) scan was done (Figure 1).
Doppler ultrasound of the patient. (A) Ultrasound of abdomen showing hydronephrosis. (B) Color Doppler image showing ureter along with mass lesion. (C) Color Doppler image showing the upper one-third of ureter and mass with inferior vena cava. (D) Color Doppler image showing the mass compressing and infiltrating the lumen of the inferior vena cava.

FIG2
On Doppler ultrasound, a ureteral mass was seen compressing and infiltrating the inferior vena cava when performing a biopsy (Figures 2A-2D).

FIG3
Biopsy was taken with precision (Figure 3). The patient also underwent an ultrasonography-guided biopsy of a ureteric and inferior vena cava mass-like lesion, which was further sent for histopathology (Figure 3).
Low- and high-power scanner images. (A) Low-power scanner image showing a core biopsy in which dense mononuclear inflammatory infiltrate can be appreciated (100x). (B) Higher magnification image showing a well-formed granuloma with numerous foamy histiocytes and macrophages representing a chronic inflammatory process (400x).

FIG4
No evidence of increased or atypical mitosis, caseous necrosis, epitheloid granuloma, or malignancy was seen in the section and thus was suggestive of a xanthogranulomatous inflammation (Figures 4A, 4B and Figures 5A, 5B).
Higher magnification (400x) images showing scattered characteristic multinucleated Touton giant cells (A) and focal deposition of hemosiderin pigment (B).

FIG5
No evidence of increased or atypical mitosis, caseous necrosis, epitheloid granuloma, or malignancy was seen in the section and thus was suggestive of a xanthogranulomatous inflammation (Figures 4A, 4B and Figures 5A, 5B).
