Lipoedematous scalp (LS) is an extremely rare condition characterised by a soft and boggy consistency in the scalp due to an increased layer of subcutaneous tissue.In this report, we present a case of LS in a 64-year-old Indian woman. Clinical examination revealed only vague boggy lumpiness involving the whole of occipital scalp extending to parietal scalp. MRI scalp showed diffuse fatty infiltration of the scalp, particularly at the posterior parietal and occipital convexity extending to both lateral aspects of the cranium, with homogeneous signal in keeping with fat. Incidentally MRI also found diffuse fatty infiltration of the parotids.The aethiopathogenesis of LS is still unknown, however it is believed that the hormone leptin could be the key hormone in the dysregulation of fat deposition and distribution. This case report highlights the subtle features with which these cases can present and explores the literature on reported cases of LS.
脂肪性头皮水肿（LS）是一种极为罕见的病症，其特征是由于皮下组织层增厚，头皮质地柔软且呈肿胀状。在本报告中，我们呈现了一名64岁印度女性患脂肪性头皮水肿的病例。临床检查仅发现枕部头皮弥漫性肿胀，延伸至顶叶头皮，质地模糊。头皮磁共振成像（MRI）显示头皮弥漫性脂肪浸润，尤其是顶叶后部和枕叶凸面，延伸至颅骨两侧，信号均匀，符合脂肪特征。偶然间，MRI还发现腮腺弥漫性脂肪浸润。脂肪性头皮水肿的发病机制尚不清楚，但人们认为激素瘦素可能是脂肪沉积和分布失调的关键激素。本病例报告强调了这些病例可能呈现的细微特征，并探讨了有关脂肪性头皮水肿报告病例的文献。
