Hepatic metastases from carcinoid tumours are typically solid, hypervascular lesions on imaging. The cystic form, mimicking an abscess, is extremely rare. We report a case of a 48-year-old female presenting with a large hepatic mass that was diagnosed as a hepatic abscess, but the ultrasound-guided biopsy showed well-differentiated grade 1 neuroendocrine tumour. CT scan of chest, abdomen and pelvis was performed, looking for the primary tumour, it revealed an endobronchial mass of the right inferior lobe. Lung biopsy by rigid bronchoscopy was taken confirming the diagnosis of a typical carcinoid tumour.

Primary hepatic lymphoma is rare. Clinical and radiological presentations are not specific. The diagnosis is often late. Chronic hepatitis or cirrhosis, especially post-viral C usually precedes primary liver lymphoma. The differential diagnosis arises mainly with other hepatic tumors, such as atypical hypovascular cellular hepatocellular carcinoma when there is liver cirrhosis and with hypovascular hepatic metastases, especially colorectal, stomach and lung metastases. Other differential diagnosis are tuberculosis or sarcoidosis, particularly when there is multiple lesions. We report the case of a 52-year woman, with a history of hepatitis C infection, presenting liver cirrhosis with multiple hepatic lesions. Radiological aspect was not specific which makes it difficult to distinguish from other hepatic tumors, especially hypovascular liver metastases.

Introduction: Vascular rings, due to the double aortic arch, are a class of congenital anomalies, considered as an important cause of tracheoesophageal compression. These anomalies are usually symptomless and thus are diagnosed fortunately when imaging is being performed for other reasons. Case Report:We report a clinical case of a patient with a history of dysphagia in his childhood, never labeled or treated. Conclusion:Currently, advanced imaging, especially computed tomography (CT), is the diagnostic procedure of choice of the double aortic arch. It can be associated with other anatomical variants. Surgical repair leads to excellent long-term prognosis.
