まとめ
縦隔リンパ腫は、腹腔内疾患がない場合でも、犬の腹腔内出血(腹部出血)を引き起こす可能性があります。このまれな原因を診断するには、徹底的な全身検査が不可欠です。
科学分野:
- 獣医学; 犬の腫瘍学; 診断画像
背景:
- 犬の急性腹腔内出血は、典型的には腹腔内病変を疑わせます。
- 縦隔腫瘍は、診断を複雑にする非特異的な臨床兆候を呈することがあります。
研究 の 目的:
- 犬の腹腔内出血のまれな鑑別診断として縦隔リンパ腫を強調すること。
- 急性腹腔内出血の症例における完全な全身検査の重要性を強調すること。
主な方法:
- 2歳のテリアミックスの症例報告。倦怠感、嘔吐、腹腔内出血を呈しました。
- 診断手順には、ポイントオブケア超音波検査、コンピューテッドトモグラフィー(CT)スキャン、および胸水の細胞診検査が含まれました。
- 治療には、グルココルチコイドおよびL-アスパラギナーゼが含まれていました。
主要な成果:
- 診断画像検査により、頭側縦隔腫瘤、胸水、およびリンパ節腫脹が明らかになりました。
- 細胞診は、中間〜大型細胞リンパ腫と一致していました。
- 治療にもかかわらず、犬は最初の診察から38日後に死亡しました。
結論:
- 腹腔内出血は、縦隔リンパ腫などの腹腔外疾患の続発症となる可能性があります。
- 腹腔内出血の根本原因を特定するには、包括的な診断アプローチが不可欠です。
- 適切な犬の癌管理のためには、縦隔腫瘍の早期認識が重要です。

Cranial and Spinal Meninges
3.9K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Cranial Nerves: Types Part I
5.1K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

Cranial Part of Parasympathetic Division
2.2K
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

Cranial Nerves: Overview and Anatomy
4.6K
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...

Cranial Bones: Lateral View
4.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
