AI Article Synopsis

  • Extraocular muscle (EOM) enlargement can result from multiple causes, which can be classified by pathogenesis, site, and clinical features.
  • Diagnosis relies on patient history, clinical examination, and necessary imaging techniques like CT or MRI, sometimes coupled with muscle biopsy.
  • Treatment should be tailored to the underlying cause, highlighting the importance of accurate diagnosis and management in EOM enlargement cases.

Article Abstract

Extraocular muscle (EOM) enlargement may be due to a variety of causes. These causes can be classified in three ways: according to pathogenesis and histopathological features, according to the site, and according to the clinical features. Diagnosis of the cause is dependent upon history, clinical examination, and investigations. Imaging with computed tomography or magnetic resonance imaging and muscle biopsy is typically necessary to make the correct diagnosis. Treatment of the patient must be directed toward the specific cause. This review emphasizes important clinical and pathological guidelines for appropriate diagnosis and treatment of patients with EOM enlargement.

Extraocular muscle (EOM) enlargement occurs in both acromegaly and Graves' disease, but the degree and pattern of enlargement have not been directly compared in these patient groups. This study investigated whether acromegaly and Graves' orbitopathy (GO) are associated with different patterns of EOM enlargement at the time of diagnosis. Retrospective cohort.

Introduction: The external jugular vein (EJV) is a superficial vein of the neck in dogs; its significance is evident in veterinary clinical practice, encompassing surgeries and interventional procedures. However, there have been no reports on EJV variations in canines, despite extensive studies on variations in the jugular veins in humans. This study aimed to use CT imaging to evaluate the prevalence of anatomic vascular variations of the EJVs in Shih Tzu dogs and to describe the clinical and CT characteristics of these vascular variants.

Kimura's disease (KD) is a rare, chronic inflammatory disorder characterized by angiolymphoid hyperplasia, peripheral eosinophilia, and elevated serum immunoglobulin E levels. It primarily affects young Asian males and typically involves the head and neck region, especially near the mandible and postauricular regions. Orbital involvement is unusual and extraocular muscle (EOM) involvement is exceedingly rare, with only a few cases reported in the literature.

Computed Tomographic Findings of Liver Cirrhosis in Dogs: Comparison between Compensated and Decompensated Cirrhosis.

Department of Veterinary Medical Imaging, College of Veterinary Medicine, Konkuk University, Seoul 05029, Republic of Korea.

This study aimed to describe computed tomography (CT) characteristics of histologically confirmed cirrhosis and to compare these CT characteristics between compensated and decompensated cirrhosis. Sixteen dogs who underwent contrast CT and histopathological examinations were included; eleven dogs were assigned to the compensated group, and five dogs were assigned to the decompensated group. Irregular hepatic contours with a diffuse nodular distribution and hepatic lymph node enlargement are common concomitant features of cirrhotic livers on CT images.

Article Synopsis
  • The study investigates the differences observed in MRI scans between bacterial orbital cellulitis (OC) and diffuse non-specific orbital inflammation (DNSOI) to aid in diagnosis.
  • A total of 32 patients were reviewed, revealing distinct MRI characteristics such as the T2 signal intensity and contrast enhancement patterns, with OC showing hyperintense signals and specific EOM involvement.
  • The findings suggest that while certain MRI features can help distinguish between OC and DNSOI, the overlap in radiological signs creates challenges in making a definitive diagnosis between infectious and non-infectious orbital inflammation.
