case_images: (A) Chest CT upon admission reveals scattered nodules and encapsulated pleural effusion in both lungs. (B) After a 10-day course of oral ceftriaxone and metronidazole, chest CT indicates a partial reduction of the pulmonary lesions. (C) Subsequent chest CT at 12 weeks post-antibiotic treatment, demonstrating significant and sustained regression of pulmonary lesions.

case_images: Immediate radiologic assessment included a chest CT revealing multiple cavitated nodules and moderate pleural effusion (Figure 1A). A repeat chest CT demonstrated a partial resolution of pulmonary lesions (Figure 1B). By the end of the 12-week antibiotic course, two months post-discharge, the patient was symptom-free, and imaging revealed substantial regression of the lung abscess (Figure 1C).
case_images: (A) The proximal lumen of the left internal jugular vein exhibits a rich blood flow signal (white arrow). (B) The middle and distal segments of the same vein display weak echogenicity with an absence of notable blood flow signals (white arrow).

case_images: Subsequent ultrasonographic examinations, including jugular venous and transesophageal cardiac ultrasounds, revealed patent flow in the proximal portion of the left internal jugular vein (Figure 2A) and occlusion in the middle and distal portions (Figure 2B), without notable cardiac abnormalities.
