Elastofibroma Dorsi: MR and CT findings

Exercise-Induced Elastofibroma Dorsi

“…With these findings, the lesion can only be considered as a connective tissue mass. On MRI, a connective tissue mass could show alternating regions of high and intermediate signal intensity (8). On the other hand, in recent years, it was claimed that the definitive preoperative diagnosis could be achieved by fine-needle aspiration; thus, a more invasive means of obtaining a tissue diagnosis could be obviated (9).…”

MR imaging findings of elastofibroma dorsi in correlation with pathological features: our experience

“…T2 hypointensity may be ascribed to the poor cellularity of the fibrous tissue and elastic fibres [6]. The internal fatty component arranged in linear or curvilinear streaks parallel to the longest axis of the lesion has high signal intensity on T1-weighted sequences, intermediate on T2-weighted sequences and shows the typical signal loss on sequences with fat suppression [7,8,14]. Lesion margins may be more or less defined, although infiltration into surrounding structures has never been documented.…”

“…La RM consente la caratterizzazione, in particolare mediante sequenze T2 pesate, degli elastofibromi del dorso tipici, per sede e caratteristiche morfo-strutturali, grazie alla possibilità di differenziare altre lesioni dei tessuti molli della regione infra-scapolare [5][6][7][8]. Lo scopo del nostro lavoro è quindi quello di analizzare le caratteristiche RM degli elastofibromi del dorso, correlando i reperti imaging con quelli anatomo-patologici, allo scopo di promuovere la riduzione del numero di biopsie ed escissioni chirurgiche ingiustificate. )…”

“…MR imaging allows characterisation of the site and morphostructural features of typical elastofibroma dorsi, in particular, with T2-weighted sequences, thanks to the possibility of differentiating it from other soft tissue lesions of the infrascapular region [5][6][7][8]. Therefore, the aim of our study was to analyse the MR features of elastofibroma dorsi by correlating imaging and pathologic findings to help decrease the number of unjustified surgical biopsies and resections.…”

Elastofibroma Dorsi

“…18 Surgical excision is recommended when elastofibroma causes functional disability, compression symptoms, an asymmetric outline of the chest wall, or when it is greater than 5 cm in diameter. [19][20][21] Marginal excision carries a very low risk of recurrence. 22 Radiologically welldocumented cases can be surgically excised without previous histopathologic confirmation.…”
