Lung carcinoma with adrenal metastasis and inferior vena cava thrombosis in an elderly patient with decompensated chronic liver disease: a case report.

Introduction: Managing patients with complex comorbidities poses significant diagnostic and therapeutic challenges. This case report details a 65-year-old male with a history of decompensated chronic liver disease (CLD) and portal hypertension, who presented with symptoms suggestive of liver disease exacerbation. He was later diagnosed with primary lung malignancy and extensive thrombosis, including the inferior vena cava (IVC) and heart chambers, a rare finding. Case presentation: A 65-year-old man with a history of smoking, alcohol consumption, and chronic liver disease presented with severe pain in the upper right quadrant, dyspnea, weakness, loss of appetite, and unintentional weight loss. Medical assessments revealed decompensated CLD with elevated bilirubin levels, low albumin, and an elevated INR. Imaging showed lung cancer with metastasis to the adrenal gland and a large IVC thrombus extending to the heart chambers. The patient decided to pursue palliative care. Discussion: When dealing with primary lung cancer and adrenal metastasis, it's important to thoroughly assess atypical presentations for IVC thrombus. Even with advances in imaging and treatments, managing IVC thrombus related to cancer is still difficult and requires a team approach. This case highlights underdiagnosis in areas with limited resources, emphasizing the need for timely advanced diagnostics such as CT and MR imaging. Conclusion: This case highlights the complexities of diagnosing and managing patients with multiple conditions. It emphasizes the need for patient-centered care and the importance of ongoing research to develop effective diagnostic and treatment strategies for conditions like IVC thrombus in the context of malignancy.
