Review Case Reports
Locked-in Syndrome Due to Meningovascular Syphilis: A Case Report and Literature Review.
We herein report a 46-year-old man presenting with locked-in syndrome secondary to meningovascular syphilis. Brain magnetic resonance imaging (MRI) demonstrated multiple acute infarctions in the left ventromedial pons, right basis pontis, and left basal ganglia. ⋯ This is a unique case of bilateral ventromedial pontine infarction caused by meningovascular syphilis that presented as locked-in syndrome. Meningovascular syphilis should be included in the differential diagnosis of uncommon stroke, particularly in young men.

Review Case Reports
Severe Immune Thrombocytopenia after COVID-19 Vaccination: Two Case Reports and a Literature Review.
We herein report two cases of coronavirus disease 2019 (COVID-19) vaccine-induced immune thrombocytopenia (ITP). A 69-year-old Japanese man developed severe thrombocytopenia after COVID-19 vaccination. He had oral bleeding and hemoptysis but no thrombotic symptoms. ⋯ A 34-year-old Japanese woman had generalized purpura after COVID-19 vaccination. Her platelet count improved rapidly after treatment with prednisolone and eltrombopag. The occurrence of two cases of ITP after COVID-19 vaccination at a single institution suggests that there could be more such undiagnosed cases, especially cases of mild secondary ITP.

Case Reports
Budd-Chiari Syndrome During Long-term Follow-up after Allogeneic Umbilical Cord Blood Transplantation.
A series of abdominal computed tomography scans of an asymptomatic 40-year-old woman with a history of umbilical cord blood transplantation (CBT) for leukemia at 19 years old revealed the long-term gradual development of a right hepatic vein thrombus and stenosis of the inferior vena cava, leading to a diagnosis of Budd-Chiari syndrome. The Budd-Chiari syndrome in this case might have been influenced by the patient's history of multiple liver abscesses after CBT and associated thrombus formation, in addition to the hormone replacement therapy with estradiol and dydrogesterone she was taking. This case provides insight into the development of Budd-Chiari syndrome.
