Focal skull lesions in children can be diagnostically challenging with a wide variety of potential etiologies. Understanding the diverse pathologies and recognizing their associated clinical and imaging characteristics is crucial for accurate diagnosis and appropriate treatment planning. We review pertinent anatomy of the scalp and calvarium and review different pathologies that can present with focal skull lesions in pediatric patients. These include neoplastic, non-neoplastic tumor-like, congenital, post traumatic, and vascular-associated etiologies. We review the key clinical and imaging features associated with these pathologies and present teaching points to help make the correct diagnosis. It is important for radiologists to be aware of the common and rare etiologies of skull lesions as well as the clinical and imaging characteristics which can be used to develop an accurate differential to ensure a timely diagnosis and initiate appropriate management.
儿童局灶性颅骨病变的病因多种多样，具有诊断挑战性。了解不同的病理学并识别其相关的临床和影像学特征对于准确诊断和适当的治疗计划至关重要。我们复习了头皮和颅骨的相关解剖结构，并复习了儿科患者中可能出现局灶性颅骨病变的不同病变。这些病变包括肿瘤性、非肿瘤性肿瘤样、先天性、创伤后和血管相关性病因。我们复习了这些病变的关键临床和影像学特征，并提出了教学要点以帮助做出正确诊断。放射科医生了解颅骨病变的常见和罕见病因以及可用于制定准确鉴别诊断的临床和影像学特征非常重要，这有助于及时诊断并启动适当的治疗。
