Lemmel’s syndrome is a rare and misdiagnosed cause of obstructive jaundice. The cause of the obstacle is a duodenal diverticulum located at the periampullary generating a compression effect on the common bile duct with secondary dilation of the extra- and intra-hepatic bile ducts. Late diagnosis of this entity is common and may lead to unnecessary further investigations and therapeutic delay. There are only few case reports of this rare condition. We report a case of 77-year-old female presenting with obstructive jaundice due to Lemmel’s syndrome. The diagnosis was made on a set of clinical, biological and radiological arguments with good improvement after medical treatment.

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.

Urachal anomalies are infrequent in the adult population and may represent a diagnostic challenge. Few cases of urachal sinuses are reported and are usually asymptomatic unless a complication occurs, most likely infectious. Infected urachal sinus' clinical manifestations are a purulent umbilical discharge, abdominal pain, and a periumbilical mass. We report the case of a late presentation of an infected urachal sinus in a male adult. Clinical and imaging features allowed accurate diagnosis. Antibiotic therapy was followed by the urachal remnant's surgical excision. The postoperative course was uneventful. Histological examination revealed no signs of malignancy.
