摘要

Background

Hemorrhagic transformation (HT) is usually seen in patients with massive cerebral infarction, or patients undergoing thrombolysis or mechanical thrombectomy, which usually occurs in the acute phase of ischemic stroke.

Case presentation

We present a case of a 61-year-old male patient with acute lacunar infarction in left posterior limb of the internal capsule with right persistent trigeminal artery (PTA). On the 20th day after the disease onset, the patient developed cerebral hemorrhage at the corresponding site. In addition. The susceptibility weighted imaging (SWI) showed multiple microbleeds in the brain.

Conclusions

PTA is a risk factor for exacerbation of acute ischemic stroke, which may lead to secondary cerebral hemorrhage through some potential mechanisms.
