Neurofibromatosis, otherwise known as von Recklinghausen disease, is a congenital hereditary disorder involving tissues of neuroectodermal or mesodermal origin. Involvement of the coronary arteries is, however, extremely rare. To the best of our knowledge, this represents the first report of off-pump coronary artery bypass grafting using the bilateral internal mammary arteries for coronary arte...
Ten members of a large family who showed manifestations of either von Hippel-Lindau disease or von Recklinghausen's neurofibromatosis were examined. Three of 10 members were found to have retinal angiomas which had not been present on fundus examination 3 years previously. These angiomas were associated with ocular and systemic signs of neurofibromatosis. These cases show overlapping manifestat...
Neurogenic tumor of lung is very rare. Only few cases have been reported in the literature. We present here two cases of bronchopulmonary neurofibromatosis in two adults. In both cases, attempts at imaging failed to diagnose the case, and it was the histological study that ensured the diagnosis of neurofibromatosis. Biopsy specimens showed bundles of spindle-shaped cells mixed with collagen, an...
Neurofibromatosis or von Recklinghausen's disease is the most common inherited syndrome predisposing to neoplasia. Carcinosarcoma is a rare malignant mixed tumor of the lung. Association of carcinosarcoma of lung with Neurofibromatosis-1 is not common. A 57-year-old man presented with history of fever, cough, hemoptysis, breathlessness, weight loss, chest pain. Multiple cutaneous neurofibromas ...
A series of reports in the literature suggest an association of neurofibromatosis Recklinghausen with intestinal tumors as carcinoids, leiomyomas and leiomyosarcomas. We present a case of a 23-year-old man with severe cutaneous manifestation of neurofibromatosis. Dysphagia was the main symptom. CT scan suggested the diagnosis of an oesophageal leiomyoma. The oesophageal muscle layers were split...
Neurofibromatosis (NF) is an otozomal dominant and multisistemic disorder. Two types were defined: Neurofibromatosis type 1 (NF1) and Neurofibromatosis type 2. Neurofibromas can be found multisystemic and can be cause difficulty for either general anesthesia or regional anesthesia. The patient is 4 years old, 15 kilograms weight, who has common neurofibroms mostly at back and cafe au lait in wh...
A 23 short-stature female patient presenting initially to gynecologist for left ovarian mass and bilateral sciatica but on further investigations it had been proved to be big pelvic neurofibroma with little findings of neurofibromatosis type 1. Surgical excision had been done without any complications. We aim to discuss the manifestations of neurofibromatosis type 1 and why lack of some finding...
MR images showed an enhancing, enlarging mass in the tectum of the midbrain in a child with neurofibromatosis type 1. The mass was presumed to be a tectal glioma, which initially enlarged then regressed in size over a 3-year period and ceased to enhance. Although a tissue diagnosis was not available, we believe the temporal evolution of this lesion is strong presumptive evidence of a hamartoma....
Neurofibromatosis may be recognized in childhood, though it is unusual for the full syndrome to be present at an early age. Thus skin pigmentation may be the only manifestation in infancy, later to be followed by the development of skin tumours, skeletal and other abnormalities. The following case of neurofibromatosis is of interest in that it occurred in a newborn infant who presented with ski...
Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder. Pseudoaneurysms formation and rupture is an unusual complication of neurofibromatosis. To date, pseudoaneurysm of the internal pudendal artery associated with NF-1 has not been reported. In this article, we present a 62-yr-old man with NF-1 suffering from spontaneous hematoma of the perinea and scrotum. A digital substraction an...
