Chondrolipoma in the Pelvic Cavity: a Case Report

Abstract

A chondrolipoma is an extremely rare form of a benign mesenchymal tumor containing mature cartilage and fatty tissue. Chondrolipomas may be found in almost any part of the body, particularly in the connective tissue of the breast, head and neck area, as well as in the skeletal muscle. However, to the best of our knowledge, chondrolipomas located in the pelvic cavity have not been reported. In this case report, we describe a case of a chondrolipoma in the pelvis, and show that it has its own characteristic imaging findings, which included the composition of fatty tissue and calcification in most parts, as well as some focal areas of chondroid tissue based on the CT and MR findings.

Ossifying chondrolipoma of the thigh

“…However, there have been few radiographic reports on the above subtypes of lipomas 15. Furtheremore, there is limited information available on the radiographic findings of chondrolipomas 3,4,13. Characteristic features of the MRI findings in our patient were the central area of tumor, intermediate signal intensity on T1-weighted images, and hererogeneous high-intensity on T2-weighted images, differing from adipose tissue.…”

“…Lipomas can occasionally have areas of bone or cartilage formation and are classified as osteolipomas or chondrolipomas, respectively 1,2. However, there have been few reported cases of lipoma with both ossification and cartilage formation 3,4. Here, we report an extremely rare case of ossifying intramuscular chondrolipoma in the thigh and review its radiographic and pathologic correlation.…”

Tumor Condrolipomatoso (Condrolipoma) De Mama

“…Aspecto general de la lesión, en la porción superior derecha se reconocen ductos mamarios proliferados sin evidencia de atipia, reconociéndose en la porción izquierda islas de cartílago hialino y tejido graso maduro. a b culta su diferenciación de otras lesiones, tales como necrosis grasa, fibroadenoma y mamas supernumerarias 5,6 , los lipomas pueden presentar combinaciones con otros elementos mesenquimales (fibrolipoma, angiolipoma), los condrolipomas se definen como lesiones lipomatosas que contienen tejido graso y cartilaginoso maduro siendo este último componente considerado como metaplasia en lesiones de larga duración 3,7 . La presencia del componente cartilaginomatoso en la mama, obliga a distinguir estas lesiones de neoplasias malignas y benignas tales como condroma extraesquelético, hibernoma, liposarcoma, condrosarcoma mixoide entre otros 2,3,5,8 .…”

Intramuscular Chondroid Lipoma: Magnetic Resonance Imaging Diagnosis by ‘Fat Ring Sign’

“…There are a limited number of case reports presenting the imaging findings of this rare tumor and, to the best of our knowledge, this is the second case of chondroid lipoma located in the pelvis. Preoperative diagnosis of chondroid lipoma is difficult due to heterogenous signal changes (1,(3)(4)(5)(6)(7)10). In this study, we present magnetic resonance imaging (MRI) findings of a histopathologically proven chondroid lipoma with a brief review of the literature and describe a new sign that may help preoperative diagnosis of chondroid lipoma.…”

“…Chondroid lipoma is a rare type of benign lipomatous lesion that can arise from any part of the body, including proximal extremities and limb girdles, trunk, head and neck, breast, and abdominal cavity, in decreasing frequency (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). There are a limited number of case reports presenting the imaging findings of this rare tumor and, to the best of our knowledge, this is the second case of chondroid lipoma located in the pelvis.…”
