Small bowel lymphoma accounts for 10%-30% of gastro-intestinal tumors. Clinical presentation is not specific. CT scans helps the diagnosis showing some characteristic appearances such as wall thickening of the loops, enlarged lymph nodes and infiltration of mesenteric fat. Pseudoaneurysmal intestinal dilatation is uncommon and may cause bowel obstruction which is a diagnostic and therapeutic emergency. We report the case of a 73-year-old man, who presented for occlusive syndrome revealing hail lymphoma. Pseudoaneurysmal intestinal dilatation is an uncommon presentation of lymphoma that should evoke the diagnosis especially when associated to wall thickening of the loops and lymphadenopathy.
Muscle metastases of bronchopulmonary cancer are rare, notably when they are revealing. They can affect all muscles of the body with a predominance of psoas, diaphragmatic and para-vertebral muscles. We report a case of psoas muscle metastasis revealing bronchopulmonary cancer in a 40-year-old patient with a long history of smoking (30 packs of cigarettes/year) presenting a chronic left low back pain with asthenia and weight loss (15 kg/year). The clinical examination was unremarkable. An abdominal computed tomography scan showing a retroperitoneal mass at the expense of the left psoas muscle, lysing the L2 vertebral and left pedicle with intraspinal extension. A complement by cervico-thoracic computed tomography scan showed a lung mass with hilar and mediastinal lymphadenopathy. A scan-guided biopsy puncture of the psoas muscle mass identified its metastatic origin. The clinical picture is often deceptive leading to diagnostic and therapeutic delay, hence the interest of the imagery as well as histological confirmation is recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
