ABSTRACT: A case of 16 yrs male patient with parosteal lipoma affecting the lower
metaphyseal end of the left femur is presented. Clinical suspicion, plain
radiographs, CT (Plain and 3 D) as well as MRI suggested a diagnosis of parosteal
lipoma. Lipomas may be defined as benign lesions of mature adipose tissue
without evidence of cellular atypia [1]. Lipomas are the most common soft tissue lesions
and surprisingly are among the rarest bone neoplasias. The most frequent
complaints are a tumoral convexity presenting as a visible or palpable mass or
a mild-intensity, dull pain. The parosteal type is a rare tumor accounting for
0.3% of all lipomas [2] and is usually asymptomatic. It is seen
commonly affecting adults aged over 40 [3]. The present
article describes a rare case of parosteal lipoma located in the femur, with
extensive hyperostosis visible on plain xray and confirmed by imaging studies
(CT and MRI). Unlike the parosteal lipomas reported in adults over 40 yrs in this
case it presented in a much younger age group.
