A 57-year-old man visited our hospital for evaluation of an abnormal shadow identified on chest radiography. Chest computed tomography findings suggested diffuse bone metastases in the thoracic spine and the bilateral ribs. Notably, 18- fluoro-deoxyglucose positron emission tomography revealed no evidence of the primary tumor.

- A 48-year-old man with a fever was diagnosed with multiple liver abscesses after a CT scan, leading to a procedure where straw-colored pus was extracted.
- The pus analysis revealed Gram-negative coccobacilli which only grew on special culture media, confirming the presence of Aggregatibacter aphrophilus through advanced techniques like mass spectrometry and genetic sequencing.
- This case marks the first reported instance of liver abscess caused by A. aphrophilus in Japan, emphasizing the need for accurate identification of rare bacteria to ensure proper treatment.
Article Synopsis
- There is no agreed-upon best method for obtaining deep tissue biopsies for advanced gastric linitis plastica (LP), but endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) shows promise as a diagnostic tool.
- A 46-year-old male with suspected advanced gastric LP had inconclusive results from initial biopsies, but EUS-FNA ultimately revealed signet ring cell carcinoma, leading to a chemotherapy referral.
- The case highlights that EUS-FNA is a potentially effective and less invasive option for diagnosing advanced gastric LP, suggesting it should be considered for deep tissue biopsy collection.
