Bennett GL, Balthazar EJ.
Ultrasound is the initial imaging modality of choice for the evaluation of suspected acute gallbladder disorders, and is often sufficient for correct diagnosis. CT also plays a vital role, however, in the evaluation of acute gallbladder pathology. CT is particularly useful in situations where ultrasound findings are equivocal. CT is also extremely valuable in the assessment of suspected complications of acute cholecystitis, particularly emphysematous cholecystitis, hemorrhagic cholecystitis, and gallbladder perforation, which are often very difficult diagnoses to establish at sonography. If CT is the initial imaging test performed in a patient with abdominal pain of uncertain etiology, recognition of the various disorders described in this article may eliminate the need for further imaging and facilitate appropriate management.PMID: 14661666 追記:出血性胆嚢炎は急性胆嚢炎のまれな合併症である.強い炎症から粘膜壊死または潰瘍形成を起こすためと言われる.胆嚢壁の動脈硬化性変化が素因となる.

Abstract:66歳男.突然上腹部痛が出現し,さらに胸部痛も加わったため来院した.腹部全体に筋性防御を認め,CT所見上,胆嚢は腫大し内部は均一で血腫と思われるhigh densityな物質で充満しており,結石は認められなかった.急性出血性胆嚢炎を疑い同日緊急手術を施行した.開腹所見では胆嚢周囲の炎症は軽度で,胆嚢頸部と胆嚢管との移行部に壊死性変化が認められ,胆嚢以外には異常所見が認められないことから,胆嚢摘出術を施行した.病理組織学的所見では体部,底部の粘膜面はほぼ正常で出血は頸部からと思われた.患者は術後17日目に軽快退院した. 追記:本邦集計78例.原因は胆石が43%と最も多い(図).
