The utilization of rapid sequences reduces the impact of fetal motion and allows for high contrast resolution of fetal structures. A thorough understanding of fetal anatomy and a systematic approach to MRI interpretation are essential for accurate diagnosis of fetal head and neck anomalies. A stepwise structural analysis of fetal head and neck structures includes the evaluation of the facial profile, including maxilla, mandible, nasal bones, and integrity of lip and palate, scalp integrity, skull morphology and proportions, and anatomy of the orbits, nasal passages, choanae, ears and neck (including visualization of the thyroid gland and airway). This approach allows for accurate and effective screening of fetal head and neck anomalies including cleft lip and palate, nasal bone abnormalities, micrognathia, craniosynostosis, skull defects, orbital anomalies, choanal atresia, ear abnormalities, goiter and head and neck masses. MRI assessment further optimizes perinatal management in cases of airway compromise by providing superior visualization of the airway column and its relationship with adjacent structures. This information helps predict a difficult airway and is essential for planning perinatal management and the delivery method, which may include EXIT (Ex-Utero-Intrapartum Treatment) procedure. Early diagnosis remains essential for parental shared decision-making, guiding counseling, and preparing families for the possible perinatal loss, limited life expectancy, or the need for supportive medical care.</p>","PeriodicalId":49541,"journal":{"name":"Seminars in Ultrasound Ct and Mri","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These include both benign and malignant processes and are classified into five categories in the 2021 WHO Classification of Thoracic Tumors: benign hyperplastic disorders, primary pulmonary neoplasms, secondary involvement of the lung, posttransplant lymphoproliferative disorders, and histiocytic neoplasms. Diagnosing PLDs is often challenging due to their histological similarity to other lymphocyte-rich interstitial lung diseases, including cellular nonspecific interstitial pneumonia (NSIP) and hypersensitivity pneumonitis. A multidisciplinary approach integrating clinical, radiologic, and pathological information is essential to reach an accurate diagnosis. This review focuses on the detailed pathological features of PLDs, particularly benign hyperplastic disorders and primary pulmonary neoplasms. It emphasizes the differential diagnosis and highlights distinguishing characteristics among key subtypes, including lymphoid interstitial pneumonia, follicular bronchiolitis, nodular lymphoid hyperplasia, Castleman disease, IgG4-related disease, and primary pulmonary lymphomas such as MALT lymphoma, diffuse large B-cell lymphoma, and lymphomatoid granulomatosis. Special attention is paid to morphological patterns, immunophenotypes, and diagnostic challenges encountered with small biopsies. Given the broad differential diagnosis and potential overlap with infectious, autoimmune, or immunodeficiency-related conditions, careful clinicopathological correlation remains the cornerstone of accurate classification and appropriate management. This review aims to enhance diagnostic clarity and support effective interdisciplinary evaluation of suspected PLD cases.</div></div>","PeriodicalId":49541,"journal":{"name":"Seminars in Ultrasound Ct and Mri","volume":"46 4","pages":"Pages 272-282"},"PeriodicalIF":1.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144561737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
