Subgaleal Lipoma: Imaging Findings

Abstract

Subgaleal lipoma is a benign tumor of adipose tissue. It should be suspected when a semi-spherical avascular mass with well-defined margins, iso-or hyperechoic in most cases, with thin internal echogenic lines parallel to the long axis of the tumor, is observed between the galea aponeurosis and periosteum of the cranial bone. We report a series of cases of three patients who underwent surgical lesion excision and whose histopathological examination findings confirmed the diagnosis of lipoma. Main Teaching Point:The presence of long continuous echogenic lines within a lensshaped soft tissue mass located beneath the galea aponeurosis may suggest the diagnosis of subgaleal lipoma.

A Case Report of Forehead Subgaleal Lipoma: Diagnostic Dilemmas and Surgical Solutions

“…Subgaleal lipomas are rare, benign soft tissue tumours that typically present as slow-growing, painless masses beneath the scalp's galea aponeurotica. Their subtle clinical appearance primarily distinguishes them and is often detected due to cosmetic concerns rather than any associated discomfort or pain [ 1 ].…”

“…Из современных диагностических ме тодов эхография является наиболее рас пространённым и широко используется для оценки состояния поверхностно рас положенных органов и тканей, доброка чественные новообразования которых требуют уточнения их границ, не всегда очевидных до морфологического исследования [1] . Эхографические методы имеют ряд пре имуществ перед другими диагностическими процедурами (в том числе КТ, МРТ) в оцен ке поражений мягких тканей: доступность, относительно невысокая стоимость и др.…”
