Introduction: Inflammatory pseudotumors, also known as inflammatory myofibroblastic tumors, are uncommon benign tumors of unknown etiology which may develop at several anatomical sites. In the urogenital tract, inflammatory pseudotumor usually affects the urinary bladder or the prostate. Inflammatory pseudotumor of the kidney is very rare. It is considered as a reactive inflammatory lesion that features very good prognosis.
Case Presentation: We present the case of a 57-year-old Moroccan man who presented with a two-month history of gross hematuria and left lumbar pain. Imaging investigations revealed a left kidney mass and pathological examination of the nephrectomy specimen showed an inflammatory pseudotumor.
Conclusion: As the preoperative definitive diagnosis of such a tumor is not possible, surgery is advised because only pathological examination of the nephrectomy specimen can establish the diagnosis with certainty. From one case report and literature review, the authors suggest a diagnostic and therapeutic strategy for the management of this rare tumor.

Renal pseudotumors, which mimic tumors on imaging, pose diagnostic challenges that can lead to unnecessary interventions. Sensing ultrasound localization microscopy (sULM) is an advanced imaging technique that uses ultrasound imaging and microbubbles as sensors to visualize kidney functional units. This study aims to investigate whether sULM could differentiate between renal pseudotumors and tumors based on the presence of glomeruli.

A 40-year-old woman presented with a mass in her OS for 2 years. Examination revealed a large conjunctival lesion on the nasal bulbar conjunctiva OS and a small upper tarsal conjunctival lesion in the OD. Biopsy OD revealed inflammatory granulation tissue, and OS revealed pseudoepitheliomatous hyperplasia with granulation tissue.

Objectives: Current literature on imaging characteristics of hepatic inflammatory pseudotumor (HIPT) is limited. This study aimed to analyze the contrast-enhanced ultrasound (CEUS) features in HIPT and compare them with contrast-enhanced computed tomography (CECT) and contrast-enhanced magnetic resonance imaging (CEMRI).
Methods: A total of 83 patients with histologically proven HIPT from two medical institutions were included in this study.
