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.

We describe the clinical course of two patients who developed tracheal compression and deviation by multinodular goiter (MNG). Case 1: A 66-year-old woman presented with thyroid swelling. Five years after the initial admission, she was diagnosed with hyperthyroidism by Graves' disease and increased bilateral thyroid lobes compressing the trachea. ⋯ Thyroglobulin was elevated from 122 to 392 ng/mL. Two cases and literature review indicated that MNG with >50 mm, solid components, and extension to the mediastinum or paralarynx were risk factors of tracheal compression and deviation. Monitoring thyroglobulin elevation can help predict the clinical course.

We present three cases with an atypical clinical course of organizing pneumonia (OP) secondary to coronavirus disease 2019 (COVID-19). Three patients were discharged with satisfactory improvement after standard steroid therapy for COVID-19. Shortly after the completion of treatment, the patients experienced a flare-up of symptoms. ⋯ Steroids were administered, and a good therapeutic response was observed. This report is the first to describe pathologically confirmed OP that developed after recovery from COVID-19. Careful follow-up is advisable for patients who have recovered from COVID-19.

Review Case Reports
Hepatocellular Carcinoma in a Patient with Tetralogy of Fallot: A Case Report and Literature Review.
We herein report a 34-year-old woman born with tetralogy of Fallot who had undergone 5 cardiac repair procedures. She developed liver nodules with congestive cirrhosis secondary to severe mitral regurgitation and an atrial septal defect. A percutaneous liver biopsy showed hepatocellular carcinoma with liver fibrosis, which was treated using transarterial chemoembolization.
