The Nutcracker Syndrome is a rare and often unrecognized cause of chronic pelvic pain and left back pain. These symptoms are due to the left renal vein compression between the aorta and the superior mesenteric artery (anterior nutcracker) or between the aorta and the spine (posterior nutcracker). The variety of clinical manifestations make the diagnosis difficult and commonly delayed. Therefore, imaging plays a key role in correcting the diagnosis by confirming the left renal vein stenosis and ruling out any differential diagnosis. Treatment options are discussed by a multidisciplinary team involving urologists, nephrologists and vascular surgeons for each patient. We report the case of 2 patients presenting chronic pelvic and lower back pain in whom clinical investigation and CT imaging findings were consistent with a nutcracker syndrome.

The hydatid cyst is a worldwide anthropozoonosis, which constitutes a health issue in Northern Africa. It may involve any organ, but it mostly affects the liver. This often asymptomatic disease can lead to multiple complications. Among them, spontaneous fistulization of a hepatic hydatid cyst in the stomach is exceptional even in endemic countries. We report the case of a 38-year-old female with febrile biliary colics due to a hydatid cyst of the liver fistulized in the stomach. The diagnosis was established based upon different clinical, biological and mainly radiological features. She received surgical treatment with satisfactory postoperative outcome.

Pneumocystis jiroveci pneumonia is a common pathology in HIV-infected but also in uninfected immunocompromised individuals. The pandemic coronavirus disease 2019 (COVID-2019) is a new type of coronavirus disease caused by SARS-COV-2, and the chest imaging is often used as complementary tool in patients’ evaluation. The imaging finding is similar with many pulmonary pathologies. Chest computed tomography scan is gold standard imaging and shows a central and diffuse distribution, ground- glass pattern with septal thickening with “crazy paving pattern.” We reported a case of 57-year-old man patient, followed in oncology for laryngeal cancer who presented of Pneumocystis jiroveci pneumonia during his follow-up. The diagnosis is confirmed by polymerase chain reaction with bronchoalveolar lavage fluid. Other immunochemical tests can be performed but are less specific. Both curative and preventive treatment in subjects at risk remains trimethoprim-sulfamethoxazole. Corticosteroid therapy may be associated depending on the case.
