RESUMO
We report an observation of a macro- and microcystic lymphatic malformation located in the right upper limb. This was a 5-year-old girl with no previous pathological history, followed since the age of 11 months for a congenital subcutaneous, painless and soft swelling of the right upper limb. Ultrasound of the soft tissue and magnetic resonance imaging (MRI) allowed the diagnosis of macro- and microcystic lymphatic malformation of the right upper limb. There is little epidemiological data on cystic lymphatic malformations (CLM). Superficial MLKs are more numerous than deep MLKs; of the superficial MLKs, nearly 75% are located in the head and neck, with an estimated incidence of 1.2 to 2.8 per 1000 births, and in the axillary hollows in 20% of cases. They affect equally males and females and different ethnic backgrounds. Involvement of the upper limb and particularly the arm is very rare. MRI plays an important role in the diagnosis and assessment of the tumor's boundaries. Treatment can be difficult because of the location of the tumor and its extension into the surrounding tissue.
RESUMO
Post-traumatic hepatic biloma is a rare complication of closed trauma of the abdomen. Generally, biloma occurs spontaneously or secondary to traumatic or iatrogenic injury to the biliary system. It can lead to significant morbidity and mortality if not diagnosed promptly and properly managed. A 4-year-old child was admitted to the emergency room with abdominal pain following a traffic accident. Clinical examinations suspected closed abdominal trauma without biological signs of icteric cholestasis. Abdominal CT scan performed within 24 hours showed a focus of hepatic laceration, and follow-up imaging at 5 days showed post-traumatic intrahepatic cystic formations. This case report aims to emphasize the importance of imaging including ultrasound, CT, MRI, MRI cholangiopancreatography (MRCP), or hepatobiliary cholescintigraphy to establish the diagnosis and guide the therapeutic gestures.
