The dynamic pre- and post-contrast MRI and helical CT imaging findings in a patient with inflammatory pseudotumor of the liver are described. On immediate post gadolinium spoiled gradient echo images multiple, ill defined, irregular, and intensely enhancing lesions were seen. Rapid washout of contrast was noted. Periportal involvement was also shown on T2-weighted fat suppressed images. Lesions showed greater conspicuity on MRI than CT. MRI findings in this rare entity led to performance of a diagnostic open surgical biopsy.

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.

Material And Methods: The study included 24 patients (8 men and 16 women) with diffuse orbital tissue involvement in GPA. Group 1 (active stage) included nine patients, while group 2 (inactive stage) consisted of 18 patients.

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.

Objective: This study aimed to outline the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDCS) in the spleen and to link these imaging features with histopathological findings.
Materials And Methods: A retrospective analysis was conducted on 11 patients (3 males, 8 females; mean age, 63.3 ± 9.
