Calcification of the linea aspera: A systematic narrative review Samantha Bee Lian Low, Andoni Paul Toms European Journal of Radiology Open Volume 6, Pages 101-105 (January 2019) DOI: 10.1016/j.ejro.2018.12.002 Copyright © 2018 Terms and Conditions

Fig. 1 Photograph of the posterior aspect of a cadaveric femur (A) and corresponding line drawing (B) demonstrating the linea aspera as a raised bony ridge with the insertion of the gluteus maximus and adductor muscles.

Fig. 2 Anteroposterior radiograph of the pelvis (A) and lateral radiograph of the right hip (B) in a 62 year old female, with gradually increasing right thigh pain, demonstrate thickening of both medial and lateral femoral cortices in the diametaphyseal junction, with a 4.5 cm partly mineralised lesion arising from the anterior aspect of the proximal femur with periosteal thickening.

Fig. 3 Axial CT (A); axial T1-weighted (B), axial (C) and coronal T2-weighted fat suppressed (D) MRI of the right proximal thigh in a 62 year old female, with gradually increasing right thigh pain, demonstrate focal bony proliferation with peri-osseous oedema and mild bone marrow oedema, with no features of a neoplastic process.

Fig. 4 Anteroposterior (A) and lateral radiographs of the left hip (B) in a 67 year old male, with left hip pain and stiffness, demonstrate a lobulated area of calcification (partially seen in (B)) overlying the posterior aspect of the proximal femoral diametaphysis with no periosteal reaction.

Fig. 5 Axial CT (A) in a 67 year old male, with left hip pain and stiffness, demonstrates cortical involvement adjacent to calcification arising from the muscular septum between the vastus lateralis and gluteus maximus at the insertion to the linea aspera. Axial T2-weighted fat suppressed (B), axial T1-weighted (C) and sagittal T1-weighted (D) MRI sequences of the left proximal thigh in the same patient demonstrate the focal calcification adjacent to the linea aspera as previously described with perilesional soft tissue oedema.

Fig. 6 Anteroposterior (A) and lateral radiographs of the right hip (B) in a 61 year old female, with pain in the posterior aspect of the right proximal femur, demonstrate amorphous calcification in the proximal femur posteriorly, better visualised on the lateral radiograph.

Fig. 7 Axial CT (A); axial T1-weighted (B) and T2-weighted fat suppressed (C) MR sequences of the right hip in a 61 year old female, with pain in the posterior aspect of the right proximal femur, demonstrate patchy linear calcification within the adductor magnus with marked oedema.

Fig. 8 Anteroposterior (A) and lateral radiographs of the right hip (B) in a 57 year old female, with right posterior thigh pain that is worse on pressure, demonstrate new bone formation/ calcification in the proximal femur posteriorly.

Fig. 9 Axial T1-weighted (A) and T2-weighted fat suppressed (B) and sagittal T2-weighted fat suppressed (C) MR sequences of the right hip in a 57 year old female, with right posterior thigh pain that is worse on pressure, demonstrate an area of thickening and intermediate T1 signal at the insertion of the gluteus maximus/lateral intramuscular septum on the posterior femur with perilesional oedema. No cortical erosion or bone marrow oedema. European Journal of Radiology Open 2019 6, 101-105DOI: (10.1016/j.ejro.2018.12.002) Copyright © 2018 Terms and Conditions
