The misdiagnosis of intestinal tuberculosis (ITB), such as Crohn's disease (CD), and subsequent treatment with immunosuppressive therapies can lead to severe outcomes. However, the differential diagnosis between these two conditions can be challenging. ⋯ In the international medical community, we encounter patients from countries, such as Myanmar, where tuberculosis is endemic. Therefore, it is necessary to understand the epidemiological background of each country to accurately distinguish between CD and ITB.

The Early Onset of Levodopa-induced Dyskinesia in a Patient with Multiple System Atrophy.
Multiple system atrophy (MSA) is a neurodegenerative disorder characterized by Parkinsonism, cerebellar ataxia, and autonomic dysfunction. While less frequent than Parkinson's disease, MSA patients with a beneficial levodopa response may occasionally present with levodopa-induced dyskinesia (LID). We herein report a 50-year-old woman diagnosed with MSA-parkinsonism who developed LID in the unilateral lower extremity 10 months after the start of levodopa treatment. In this case, the distribution of LID, the timing of its onset, and the presence of LID despite relatively poor levodopa responsiveness were distinctive.

Objective Radwisp™ is a fluoroscopic video analysis workstation recently developed to evaluate pulmonary circulation, thereby obviating the need for contrast medium or breath-holding. This study validated Radwisp as a diagnostic tool for acute pulmonary embolism (APE) and evaluated its potential utility in patients with symptoms of suspected APE. Methods The study included 10 patients (mean age, 69±16 years old) who were admitted to our hospital for suspected APE based on symptoms and physical examination findings between January 2020 and April 2021. ⋯ Among the residents, the sensitivity and specificity were 88% and 35%, respectively, and the positive and negative predictive values were 76% and 55%, respectively. Conclusion This study showed an initial validation of Radwisp for diagnosing APE, revealing a high sensitivity but not yet achieving a high specificity. Further studies with a larger number of cases are needed to thoroughly evaluate the diagnostic performance.

A 54-year-old woman presented with an elevated esophageal lesion. Computed tomography (CT) and magnetic resonance imaging revealed a mass in the pancreatic head. Endoscopic ultrasound (EUS) showed a well-defined, round, hypoechoic mass, which was considered lymph node enlargement. ⋯ The pathologically confirmed epithelial cells and multinucleated giant cells were positive for T-SPOT. Clinically, tuberculous lymphadenitis and esophageal tuberculosis were suspected, with successful treatment with anti-tuberculosis therapy resulting in a good response. Our findings suggest that an EUS-FNAB is useful for diagnosing esophageal tuberculosis.
