RT Journal Article SR Electronic T1 Giant left gastric artery aneurysm with intrathoracic extension JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 199 OP 201 DO 10.15537/smj.2025.46.2.20240847 VO 46 IS 2 A1 Akcali, Ayhan A1 Ogan, Bilal A1 Buğra Sezen, Celal A1 Metin, Muzaffer YR 2025 UL http://smj.org.sa/content/46/2/199.abstract AB Splanchnic artery aneurysms, particularly those involving the left gastric artery, are infrequent occurrences and often lack noticeable symptoms, but their rupture involves a significant risk of mortality. We present a case involving an unruptured left gastric artery aneurysm (LGAA) that extended into the right hemithorax. This case report outlines the categorization, clinical manifestations, and diagnostic challenges associated with such aneurysms. Our findings could offer valuable insights for clinicians and radiologists when adopting a systematic approach for the early detection and management of LGAA.
