Metastatic Liposarcoma to the Parotid

Distant metastases of the parotid gland are uncommon. They arise from primary tumors located in the head and neck, mainly melanoma and epidermoid carcinoma. Other histological types of metastasis are very rare. We report an exceptional case of parotid metastasis of myxoid liposarcoma in a 42-year-old man and insist on the worse prognosis of this entity

Vein of Galen Aneurysmal Malformation revealed by a severe heart failure and pulmonary hypertension in an infant

Neonatal and pediatric heart failure is commonly caused by congenital heart diseases, especially by large left-to-right shunting. It is rarely related to a Vein of Galen Aneurysmal Malformation (VGAM). Diagnosis and management of these cerebrovascular malformations in infancy are still difficult and remain a medical challenge. We report the case of a 2-month-old infant hospitalized for heart failure. In addition to symptoms relating to heart failure, the child presented in an agitated state with opisthotonic posture. Echocardiography showed dilated right heart cavities with pulmonary hypertension and no heart defect. Brain magnetic resonance imaging scanning confirmed the diagnosis of VGAM, showing multiple cerebral parenchyma damages. The baby was treated with diuretics and an angiotensin-converting-enzyme inhibitor leading to stabilization of her heart failure. Given the gravity of the neurological sequelae, no embolization procedure was planned for this child. She died 5 years later of acute heart failure

Spectrum of gastrointestinal lesions of neurofibromatosis type 1: a pictorial review

Abstract Neurofibromatosis type 1 (NF1) is one of the most common genetic disorders. Gastrointestinal manifestations of NF-1 are seldom thought of in routine clinical practice and might thus be significantly under-recognised. Their heterogeneous spectrum ranges from localised microscopic proliferative lesions to grossly recognizable mass-forming neurofibromas, neuroendocrine and gastrointestinal stromal tumours (GIST). The aim of this study is discussing the imaging evaluation and characterisation of the abdomen lesions in patients with NF1. Teaching Points • Neurofibromatosis type (NF-1) is one of the most common single gene disorders. • Every organ system can be involved and intra-abdominal manifestations are underestimated. • The NF1 abdominal manifestations comprehend five categories of tumours. • Neurogenic tumours including with neurofibromas are the most common type. • Early diagnosis of abdominal manifestations of NF-1 based on imaging patterns is necessary for appropriate treatment to avoid serious organic complications related to tumour mass
