[en] The authors report a retrospective study concerning 32 cases of non Hodgkin lymphoma of the small intestine, histologically confirmed. All patients underwent digestive opacification. Ultrasonography was performed in 15 cases and CT scan was performed in 6 cases. The average age was 36 years and the sex-ratio was 3.4. The classical radiological signs describes in the literature were found in our patients. The diagnosis of lymphoma was easily suggested in the presence of polymorphic and multifocal lesions, and especially the aneurysmal appearance. Abdominal sonography and computed tomography contributed to the diagnosis and also helped to relate an abdominal mass to its digestive origin, by showing a classical 'sandwich' appearance.

[en] Full text: We report the case of a patient with a single liver metastasis of a mucinous colonic carcinoma that mimics a haemangioma in T₂-weighted sequences. Although a very high T₂ signal in non-cystic lesions is highly specific for the diagnostic of haemangioma, the use of gadolinium-enhancement MRI is recommended. In patients with a history of neoplasia, the diagnosis of benign liver nodules should be made with caution

[en] Radiation-induced lung disease (RILD) is frequent after therapeutic irradiation of thoracic malignancies. Many technique-, treatment-, tumor- and patient-related factors influence the degree of injury sustained by the lung after irradiation. Based on the time interval after the completion of the treatment RILD presents as early and late features characterized by inflammatory and fibrotic changes, respectively. They are usually confined to the radiation port. Though the typical pattern of RILD is easily recognized after conventional two-dimensional radiation therapy (RT), RILD may present with atypical patterns after more recent types of three or four-dimensional RT treatment. Three atypical patterns are reported: the modified conventional, the mass-like and the scar-like patterns. Knowledge of the various features and patterns of RILD is important for correct diagnosis and appropriate treatment. RILD should be differentiated from recurrent tumoral disease, infection and radiation-induced tumors. Due to RILD, the follow-up after RT may be difficult as response evaluation criteria in solid tumours (RECIST) criteria may be unreliable to assess tumor control particularly after stereotactic ablation RT (SABR). Long-term follow-up should be based on clinical examination and morphological and/or functional investigations including CT, PET-CT, pulmonary functional tests, MRI and PET-MRI. (authors)
