感染性単核球症による自発性非外傷性脾破裂
Irish medical journal
|February 23, 2026
まとめ
エプスタイン・バー・ウイルス(EBV)は、まれではあるが重篤な状態である自発性脾破裂を引き起こす可能性がある。CTスキャンによる迅速な診断と、脾臓摘出術などの適時介入は、患者の生存にとって極めて重要である。
科学分野:
- 医学;放射線学;外科学
背景:
- エプスタイン・バー・ウイルス(EBV)感染は、一般に感染性単核球症として知られ、まれではあるが重篤な合併症を引き起こす可能性がある。; 自発性脾破裂は、緊急の医療処置を必要とする生命を脅かす状態である。
研究 の 目的:
- エプスタイン・バー・ウイルス感染に続発する非外傷性脾破裂の症例を報告する。; このまれな病態における画像検査の診断的有用性と管理戦略を強調する。
主な方法:
- 感染性単核球症の症状を呈し、その後血行動態の破綻を来した若年成人患者の症例研究。; 診断ワークアップには、ベッドサイド超音波検査および造影CTスキャンが含まれた。; 管理には緊急開腹手術および脾臓摘出術が含まれた。
主要な成果:
- 患者は発熱、咽頭痛、それに続く腹痛と嘔吐を呈し、脾破裂を示唆していた。; CT画像検査では、著明な腹腔内出血、脾臓血腫、および活動性の出血が明らかになった。; 緊急脾臓摘出術が成功裏に施行され、合併症のない回復に至った。
結論:
- EBV関連非外傷性脾破裂は、まれではあるが極めて重要な診断である。; 造影CTは、脾臓損傷および活動性出血を確認するために不可欠である。; 管理は患者の安定性に合わせて調整されるべきであり、血行動態的に不安定な患者には脾臓摘出術が適応となる。

Disorders of Leukocytes
2.1K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Esophageal Perforation-I: Introduction
669
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Secondary Lymphoid Organs
9.8K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
