摘要

髓外造血（EMH）是一种罕见的情况，在骨髓外形成造血组织。我们提出一个病例的病人长期骨髓纤维化和地中海贫血，诊断为肝内EMH （IEMH）通过手术病理。本病例描述其病因、发病机制及误诊原因，重点介绍IEMH的超声造影（CEUS）和磁共振成像（MRI）的特点。由于年龄和病变活动的不同，IEMH的MRI表现多种多样。值得注意的是，它首次描述了IEMH在超声造影上的增强模式，这是该疾病潜在的独特成像特征。

Contrast-Enhanced Ultrasound Reveals a Rare Pseudo-Malignant Lesion: Intrahepatic Extramedullary Hematopoiesis.

Extramedullary hematopoiesis (EMH) is a rare condition where hematopoietic tissue forms outside the bone marrow. We present a case of a patient with long-standing myelofibrosis and thalassemia, diagnosed with intrahepatic EMH (IEMH) through surgical pathology. This case describes its etiology, pathogenesis, and the causes of misdiagnosis, mainly focusing on the characteristics of contrast-enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) of IEMH. The MRI manifestations of IEMH are diverse due to differences in the age and activity of the lesions. Notably, it provides the first description of IEMH's enhancement pattern on CEUS, a potential unique imaging feature of this condition.

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
