The absence of any antecedent trauma or surgical procedure in our case makes us conclude that the tumour rose de-novo. Radiological findings vary as a result of its disparate content of cellular, matrix water content and infiltration. Contrast enhancement is however universal. Differential diagnoses of abdominal wall tumours are extensive and include fibrosarcomas, lymphomas, rhabdomyosarcomas, neurofibrosarcomas, benign fibrous tumours of pleura, and primitive neuro-ectodermal tumours. Historical information in conjunction with the imaging features is helpful.
Definitive diagnosis is established by histopathology.
Radiotherapy is reserved for surgically inoperable tumours. Prompt recognition of the entity and its anatomic delineation is essential for both pre-operative evaluation as well as institution of appropriate treatment. Cift ci E, Erden I, Koral K, Akyar S.
