Inflammatory pseudotumor (IPT) is a rare benign tumor of unknown etiology that can occur in almost any organ system. It has neoplastic features such as local recurrence, invasive growth, and vascular invasion, leading to the possibility of malignant sarcomatous changes. The clinical presentations of colonic IPT may include abdominal pain, anemia, a palpable mass, and intestinal obstruction. A few cases of colonic IPT have been reported, but colonic IPT with pedunculated morphology is very rare. Furthermore, since it can mimic malignant polyps, understanding the endoscopic findings of colonic IPT is important for proper treatment. Herein, we present a case of colonic IPT with pseudosarcomatous changes, presenting as a large polyp, mimicking a malignant polyp in the cecum, along with a literature review. [ABSTRACT FROM AUTHOR]

Brucellosis is a multisystem disease w ith varios clinical symptoms. Neurobrucellosis is a rare but serious manifestation of brucellosis. A 60-year-old man with a previous diagnosis of brucellar spondylitis presented with sudden onset of aphasia and numbness of the right upper extremity. Cerebral angiography showed diffuse narrowing and dilatation on the distal branches of both the anterior cerebral artery (ACA) and the left middle cerebral artery (MCA) which indicated cerebral vasculitis, and the parent's Brucella agglutinintiter was 1:1280. After combined antimicrobial and steroid therapy was started, the patient's condition improved significantly, and he was discharged after 1 month. Antimicrobial therapy was continued for 16 months on an outpatient basis, and the last Brucella agglutinin titer was "1:40. To our knowledge, this is the first case of relapsed neurobrucellosis with vaseulitis in Korea to have been treated successfully. [ABSTRACT FROM AUTHOR]
