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.

Septic pulmonary embolism is an uncommon disorder that is most often seen in patients with predisposing situations (intravenous drug use, endocarditis, septic thrombophlebitis, central venous catheter infections…). The clinical signs are non-specific. CT scan is useful for diagnosis showing bilateral pulmonary nodules with some orienting signs. We report a case of a 43-year-old woman, with a history of hemodialysis via a tunneled jugular catheter, who presented with acute respiratory distress and fever, chest CT showed multiple bilateral nodules, some of which are excavated. Blood cultures showed a staphylococcus aureusbacteremia. The diagnosis of septic emboli was made in view of all the clinical, biological, and radiological elements.

Background. Emphysematous osteomyelitis and emphysematous pyelonephritis are both rare entities responsible for a high death rate. The first is defined by the presence of intravertebral or intraosseous gas, while the second is infectious damage to the renal parenchyma and perilesional tissues caused by gas-producing microorganisms and is, therefore, characterized by the formation of gas. Imaging plays a crucial role in making a rapid diagnosis and, thus, the initiation of the necessary treatment. Case Report. A 66-year-old woman with a medical history of type 2 diabetes mellitus and hypertension presented with the altered general condition and flank pain for 5 days, associated with fever and chills. The patient’s vital signs were remarkable with a disturbed biological workup, which led to emergency abdominal and pelvic computed tomography scanning that revealed emphysematous osteomyelitis of the spine and emphysematous pyelonephritis. Conclusions. The coexistence of emphysematous pyelonephritis and emphysematous osteomyelitis is a rare life-threatening entity, occurring in patients with comorbidities such as diabetes mellitus. Computed tomography is currently the gold standard in making the positive diagnosis, staging, for a quick and better management and, thus, a favorable prognosis.
