Intravenous misplacement of the nephrostomy catheter following percutaneous nephrolithotomy (PCNL) is severe and extremely rare, and little information is available about this complication. Because the patient's prognosis may be poor, sufficient attention should be paid to early identification and treatment of this complication. We report a case with intravenous misplacement of nephrostomy catheter and severe bleeding from the catheter after PCNL was transferred to our hospital. The patient was successfully managed using a two-step intervention. First, the patient underwent embolization of the pseudoaneurysms in renal parenchyma, then underwent catheter withdrawal under digital subtraction angiography (DSA) and control bleeding by pushing the absorbable hemostatic material (Surgicel) into the tunneled renal drainage. There were no severe complications. Withdrawal could be performed by open surgery or under the supervision of imaging modalities. Some reports showed that minimally invasive management was safer and less invasive than open surgery.

Phlebosclerotic colitis (PC), also known as idiopathic mesenteric phlebosclerosis, is a rare disease resulting in ischemic colon due to venous sclerosis and calcifications that can be identified by characteristic imaging features on computed tomography and colonoscopy. Clinical examination reveals nonspecific symptoms with slow progression in the majority of cases. Patients with PC often require late-stage hospitalization and colectomy. We report a 79-year-old man with long-term clinical symptoms who used herbal medicines. Computed tomography and colonoscopy studies revealed several classical PC characteristics, and the patient subsequently underwent emergency total colectomy.

Chordoid gliomas are uncommon neoplasms located within the anterior portion of the third ventricle. In this article, we aimed to describe the clinical presentation, magnetic resonance imaging characteristics, histological findings, and surgical treatment applied to a case of chordoid glioma. Chordoid gliomas are typically observed as solid masses within the anterior segment of the third ventricle, characterized by homogenous and vivid enhancement. Despite being classified as a low-grade neoplasm, the outcome of choroid glioma is often uncertain.
