Cholesterol granuloma is a histological term used for the description of a tissue response to a foreign body such as cholesterol crystals. Cholesterol granuloma is histologically characterized as fibrous granulation tissue containing cholesterol crystals within surrounding giant cells. Cases of cholesterol granuloma of the pancreas are very rare. We report a case of a 47-year old male who had a cholesterol granuloma of the pancreas. Abdominal CT showed 24 mm-sized cyst in the pancreas and peri-pancreatic regional mass infiltrating to the stomach. PET-CT revealed increased 18F-FDG uptake at the cyst and peri-pancreatic mass. Thus, Whipple's operation was done. The disease was confirmed by surgical pathologic examination of the tissue. Pathologic examination of resected specimen showed numerous cholesterol crystals surrounded by multinucleated foreign body giant cells. We report on this case and give a brief review of the literature.

This study aimed to investigate the surgical efficacy of middle ear cholesterol granuloma using otoendoscopy. A total of 23 patients (9 males and 14 females) aged (38±18) years who were diagnosed with middle ear cholesterol granuloma at the Otology Medical Center, the First People's Hospital of Foshan from May 2020 to August 2023 were retrospectively analyzed. Based on clinical characteristics of the lesions, the patients were categorized into retention type and granulation type; the latter was further subdivided into localized and extensive types.

Petroclival lesions represent a surgical challenge during the endonasal endoscopic approach, as they may involve maneuvers with severe comorbidity. To avoid the morbidity caused by these maneuvers, a contralateral transmaxillary approach (CTA) has been proposed to complement the endoscopic endonasal approach. The aim of our study is to review the safety and efficacy of this approach.

To control schistosomiasis mansoni, it is important to attempt preventing the worms' egg-induced pathology in the liver and limiting pathogen transmission following egg exit from the intestines to the exterior. Therefore, the present study aimed to clarify the reasons behind the decades-long riddle of periovular granulomas downmodulation in the liver, but not the small intestine, with the progression of murine schistosomiasis mansoni. Outbred female CD-1 mice were percutaneously exposed to 15 cercariae.

Background: Cholesterol granuloma (CG) is a benign entity characterized by the presence of cholesterol crystals and foreign body giant cells. This condition can be attributed to cholesterol crystals that are deposited in the tissues and react with foreign body giant cells, resulting in granuloma formation. Lesions commonly develop in the otolaryngeal region, such as the middle ear.

Intraoperative patient movement under general anesthesia, even with multiple monitoring modalities and adequate anesthetic depth, is rare but can lead to serious complications. Such movements are particularly dangerous in neurosurgical procedures, where precision is crucial. Similar risks exist in ophthalmic, spinal, and cardiac surgeries, where patient immobilization is vital to prevent adverse outcomes.
