# Lung cancer brain metastasis and hemorrhagic cerebral venous thrombosis: experiences and lessons

## TL;DR

This paper reports a rare case of lung cancer brain metastasis combined with hemorrhagic cerebral venous thrombosis and highlights the challenges in diagnosis and treatment.

## Contribution

The paper presents a case study and lessons learned from a rare combination of lung cancer brain metastasis and hemorrhagic CVST.

## Key findings

- The incidence of lung cancer brain metastasis combined with hemorrhagic CVST is very rare.
- Clinical manifestations are not specific, requiring detailed medical history and imaging for accurate diagnosis.
- Timely treatment of the responsible lesion is crucial to relieve symptoms and optimize outcomes.

## Abstract

The incidence of lung cancer brain metastasis combined with hemorrhagic cerebral venous sinus thrombosis (CVST) is very rare, and the understanding and treatment experience of this case is insufficient. We reported a case of lung cancer brain metastasis accompanied by venous sinus thrombosis, and describe the diagnosis and treatment plan for colleagues to learn from experience and lessons.

1. The incidence of lung cancer brain metastasis combined with hemorrhagic CVST is very rare, and the understanding and treatment experience of this case is insufficient.

2. The clinical manifestations of metastatic tumors and CVST in patients are not specific, and the evolution of the medical history should be inquired in detail, with careful physical examination and imaging review.

3. CVST should be considered in patients with risk factors. The incidence of hemorrhagic CVST is relatively rare, and due to atypical symptoms and imaging manifestations, it is easy to miss and misdiagnose.

4. The responsible lesion should be determined based on the evolution of the medical history, the treatment of the responsible lesion should be prioritized, symptoms should be relieved in a timely manner and the optimal treatment time should be strived for.
