Esophageal Liposarcoma: A rare tumor.

Esophageal liposarcoma is a rare type of tumor. This case report documents the presentation, diagnosis, and management of a 74-year-old male with a medical history including diabetes mellitus, asthma, and hypertension. The patient's primary complaint was dysphagia, accompanied by regurgitation and substantial weight loss over a six-month period. Diagnostic evaluation revealed a sizable esophageal liposarcoma, which was successfully resected through surgery. Follow-up assessments demonstrated the absence of residual mass. Esophageal liposarcomas, though rare, should be considered in patients presenting with dysphagia or chest discomfort. Surgical resection is the mainstay of treatment, with the recommendation for extended postoperative surveillance given the limited available data regarding long-term prognosis.

Imaging of Pulmonary Post-Tuberculosis Sequelae.

Worldwide, tuberculosis (TB) is one of the top 10 causes of death, and the leading cause from a single infectious agent. Pakistan has an overwhelming burden of TB and it is a major health hazard for the majority of the rural population. The lung continues to be the most common site of involvement and even after completion of treatment residual changes remain which may affect quality of life. Complications of TB after treatment completion can often be misinterpreted for other active diseases so it is important to recognize and understand the radiologic manifestations of the thoracic sequelae. Post TB sequelae can be categorized into parenchymal, airway disease, pleural/chest wall, vascular and mediastinal. These residual changes can be minor however, some can be debilitating and even fatal.The purpose of this pictorial review is to show the spectrum of residual changes seen on chest radiography and/or computed tomography that persist after treatment completion and bacteriological cure.

Safety of Percutaneous Transhepatic Biliary Stenting in Patients with Obstructive Jaundice.

OBJECTIVE: To determine the safety of percutaneous transhepatic biliary stenting (PTBS) in patients with obstructive jaundice. STUDY DESIGN: A case series. PLACE AND DURATION OF STUDY: Department of Radiology, The Aga Khan University Hospital Karachi, Pakistan, from February 2012 to April 2013. METHODOLOGY: Patients with obstructive jaundice due to any cause referred for percutaneous transhepatic biliary stenting were included in the study. Patients were excluded if they had undergone previous ERCP, had guided transhepatic biliary stenting, previous percutaneous transhepatic biliary stenting and were lost to follow-up. Follow-up was taken at a 2, 4 and 6 week interval and clinical outcome was assessed as the difference between the bilirubin levels at base line and 6 weeks after PTBS, which was measured using Freidman's test. RESULTS: A total of 102 patients were included; 59 (58%) were males and 43 (42%) were females. The age ranged from 21 to 89 years. A total of 30 patients experienced complications making an overall complication rate of 29.4%; 20 experienced minor and 10 experienced major complications. Pain was the most frequent minor complication (n=15 patients, 14.7%) followed by biliary leakage, fever and cholangitis. Major complications included death in 10 (10%) patients followed by biliary peritonitis and septicemia. CONCLUSION: PTBS achieved satisfactory palliation with a low complication rate in patients with obstructive jaundice.
