A fortuitous discovery of a neurofibroma in a female patient with type 1 neurofibromatosis: a case report.

Neurofibromatosis type 1 (NF1) is a neurocutaneous condition with an autosomal dominant pattern of inheritance. This congenital disease is characterized by a wide spectrum of clinical manifestations and degree of severity. This case report describes a female patient in her early 20s who presented with a complaint of lumbosciatica-like pain evolving for several months. The condition initially escaped the attention of clinicians until a lumbar computed tomography scan and spinal magnetic resonance imaging were performed. The patient was then transferred to the general surgery department, where a clinical diagnosis of NF1 was established. The clinical manifestations were specific for this disease, including café-au-lait macules, plexiform neurofibroma, and a history of neurofibromatosis in her mother. The patient underwent surgical resection of the neurofibroma, which resulted in a favorable outcome. However, 2 years later, a new mass attached to the second lumbar spinal nerve was revealed by a follow-up computed tomography scan. Long-term and close follow-up of NF1 is required because of the high risk of malignancy and recurrence in NF1 patients.

Co-Existence of An Unusual Branching Pattern of Celiacomesenteric Trunk With Complete Common Mesentery in a 48-Year-Old Man: A Case Report.

Celiacomesenteric trunk (CMT) refers to the common origin of celiac trunk and superior mesenteric artery which is a very rare anatomical variation. CMT is incidentally diagnosed during angiography or abdominal computed tomography scanning. The diagnosis of CMT may inform surgical practice and prevent damage during invasive radiologic procedures, lowering thus the rate of iatrogenic errors. Complete common mesentery is in its turn a rarer congenital anomaly that arises from an abnormal rotation of primitive small intestine during embryonic development. We report a case of a 48-year-old man, suffering from chronic abdominal pain, and postprandial discomfort. The patient underwent an abdominal contrast-enhanced computed tomography that detected a CMT associated with common complete mesentery. According to our review of bibliography, this is the first case report to simultaneously report both congenital anomalies (CMT and common complete mesentery). Furthermore, the CMT described here has not been described in previous classifications and represent a novel anatomical variation of CMT.

[Liver regeneration after major hepatectomy. Evaluation of dogs hepatectomy]. / La regeneration hepatique apres hepatectomie. Etude expérimentale sur le chien.

OBJECTIVES: The aim of our study is to evaluate anatomic regeneration and metabolic derangement of the liver after major resection in dogs. METHODS: This is an experimental study on 9 dogs; we divided the dogs in two groups: the first group (5 dogs) underwent at one go major hepatectomy (90% of the liver). The second group (4 dogs) underwent successively a resection of 75% of the liver and a second resection of 90% of the restored liver six months later. All dogs underwent a metabolic and morphologic studies of the liver and of their kidney function. RESULTS: In the first group; all dogs which underwent 90% hepatic resection died 48 hours after the surgical resection of hepatic insufficiency. The ultra microscopic study showed the role of portal hypertension in hepatic degeneration on the first group. In the second group, the dogs survived the first resection, and our study shows a regeneration of the liver after resection and sub normal hepatic function. CONCLUSION: The liver is able to regenerate after minimally resection but major resection must be done by successively resection to avoid hepatic dysfunction, but the time between resection must be evaluate later.
