Suspected brain metastasis from lung cancer mimicking intracerebral hemorrhage: A case report

RATIONALE: Hemorrhage rarely occurs in a solitary brain metastasis from lung carcinoma. PATIENT CONCERNS: We report on a 54-year-old man who presented with a severe headache for 4 days. DIAGNOSES: Based on computed tomography and magnetic resonance imaging enhancement, the patient was diagnosed with a suspected hemorrhagic brain metastasis from lung carcinoma. INTERVENTIONS: The patient's family rejected a pathological examination. OUTCOMES: The patient's family requested discharge after diagnosis. LESSONS: The present case emphasizes the need to consider hemorrhagic metastasis as a differential diagnosis in patients presenting with solitary intracerebral hemorrhage whose location is uncommon, especially when the poor general state of the patient cannot be attributed to hypertensive intracerebral hemorrhage.
