1/125. Negative pressure pulmonary hemorrhage.Negative pressure pulmonary edema, a well-recognized phenomenon, is the formation of pulmonary edema following an acute upper airway obstruction (UAO). To our knowledge, diffuse alveolar hemorrhage has not been reported previously as a complication of an UAO. We describe a case of negative pressure pulmonary hemorrhage, and we propose that its etiology is stress failure, the mechanical disruption of the alveolar-capillary membrane.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
2/125. The decline and early fall of neonatal pulmonary hemorrhage.Seven years' experience (1965-1972) with neonatal pulmonary hemorrhage at the University of colorado was reviewed. Pulmonary hemorrhage still occurs frequently as a preterminal event in hyaline membrane disease. As an isolated "pure" entity, however, pulmonary hemorrhage has shown a marked decline. This phenomenon is probably related to advances in neonatal intensive care. The radiographic pattern of "pure" pulmonary hemorrhage in the newborn is most commonly a diffuse alveolar infiltrate. Since pure hemorrhage is now an uncommon entity, the radiologist can reasonably suggest this diagnosis on rare occasions only, in the clinical setting of profound hypoxia.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
3/125. MR imaging of a hemorrhagic and granulomatous cyst of the ligamentum flavum with pathologic correlation.cysts of the ligamentum flavum are uncommon causes of neurologic signs and symptoms and usually are seen in persons over 50 years of age. We report a case of an epidural cyst located in the ligamentum flavum, which contributed to spinal stenosis in a 30-year-old man. Radiologic features were similar to those of a synovial cyst, but synovium was not identified histologically. The imaging and pathologic features were unusual, including hemorrhage and a fibrohistiocytic reaction with giant cells.- - - - - - - - - - ranking = 4.0283814575057keywords = ligament (Clic here for more details about this article) |
4/125. ligamentum flavum hematoma in the lumbar spine.A patient who presented with symptoms suggestive of nerve root compression secondary to an extradural mass was found to have a hematoma in the ligamentum flavum. Pathological examination of surgical specimens revealed an old hemorrhage, and hemosiderin deposits around organized granulation tissue within the ligamentum flavum. Vessels within the ligamentum flavum had, presumably, ruptured during minor trauma when the patient stood up.- - - - - - - - - - ranking = 2.0141907287529keywords = ligament (Clic here for more details about this article) |
5/125. Macular ring in a patient with Terson's syndrome.PURPOSE: To report on a pigmented finding in the macula that is unique to Terson's syndrome, and was previously described only once. METHOD: A 49-year-old man underwent vitrectomy for vitreous hemorrhage due to Terson's syndrome. During surgery the retina was exposed, and a pigmentation was noticed around the macula. Follow-up of the macular finding is presented. RESULTS: At surgery a pigmented "ring" encircling the macula was revealed. Two and six months later, the pigmented line was still noticed, and an epiretinal membrane appeared in the temporal macula. CONCLUSION: Terson's syndrome may be associated with a pigmented "ring" encircling the macula, a finding that may be a result of a detachment of the internal limiting membrane (ILM). The epiretinal membrane that was later noticed, might also be related to the damage to the ILM.- - - - - - - - - - ranking = 3keywords = membrane (Clic here for more details about this article) |
6/125. Aortopulmonary collateral artery embolization during postoperative extracorporeal membrane oxygenation after arterial switch procedure.Aortopulmonary collateral arteries sometimes complicate cyanotic congenital heart defects. Combined with a relevant left-right shunt, this could result in massive airway bleeding during and after corrective surgery. A preoperatively diagnosed 1.2 mm small aortopulmonary collateral artery in a newborn suffering from transposition of the great arteries caused life-threatening airway bleeding during surgery. Postoperative extracorporeal membrane oxygenation (ECMO) was necessary, and coil embolization was performed on ECMO to terminate pulmonary bleeding.- - - - - - - - - - ranking = 5keywords = membrane (Clic here for more details about this article) |
7/125. Treatment of primary pure angiosarcoma of ovary with multiple lung metastases: a case report.Angiosarcomas rarely involve the female genital tract. There have only been sporadic case reports of angiosarcomas of the cervix, uterus, vagina, parametrium, broad ligament and pelvis, and only 11 well-documented case reports of primary ovarian angiosarcoma in the English language literature to date. We present a case of primary pure ovarian angiosarcoma with lung metastasis that had partial response after chemotherapy with adriamycin and ifosfamide. But pulmonary hemorrhage and respiratory failure resulted in her death 7 months after initial diagnosis.- - - - - - - - - - ranking = 0.67139690958429keywords = ligament (Clic here for more details about this article) |
8/125. Systemic lupus erythematosus presenting with haemorrhagic manifestation.A 26-year-old female presented with an episode of severe mucus membrane bleeding. Investigations revealed prolonged prothrombin time (PT), and partial thromboplastin time (PTT), normal thrombin time (TT) and reptilase time, thrombocytopenia, a positive test for lupus anticoagulant (LA), as well as anti-cardiolipin antibodies (ACL). A toxicology screen for toxic drugs and coumadin was negative. Coagulation factor assays revealed low levels for factor II and XII. Low level inhibitor to factor II was demonstrated. Patient had a negative VDRL test and positive anti-nuclear antibodies (ANA). The diagnosis of acquired hypoprothrombinaemia secondary to circulating inhibitor induced by LA was made, and then the patient was started on prednisone, which led to cessation of the bleeding and normalization of PT and PTT, as well as an increase of factor II and factor xii levels. A few months later, the patient developed arthralgia and alopecia, and antibodies against double-stranded dna were detected, and the diagnosis of systemic lupus erythematosis (SLE) was confirmed. The patient continued to have mild prolongation of PT and PTT while on a low dose of prednisone, but she had no bleeding symptoms. A computed tomography scan of the brain was carried out for unexplained central nervous system (CNS) symptoms, and it revealed mild hydrocephalus, which was thought to be part of the CNS manifestations of SLE. It was concluded that patients with SLE may present with haemostatic defects that are a result of either platelet-related causes (quantitative or qualitative) or coagulation factor deficiency secondary to circulating inhibitor, or both, in the absence of other features of SLE which may appear later.- - - - - - - - - - ranking = 1keywords = membrane (Clic here for more details about this article) |
9/125. Sequential development of pulmonary hemorrhage with MPO-ANCA complicating anti-glomerular basement membrane antibody-mediated glomerulonephritis.We report a case of rapidly progressive glomerulonephritis caused by anti-glomerular basement membrane (anti-GBM) antibodies that progressed to end-stage renal disease in a 67-year-old woman with diabetes. Intensive combined immunosuppressive therapy with methylprednisolone bolus, oral prednisone, and cyclophosphamide led to negativity of anti-GBM antibodies but was not able to restore renal function. After 28 months of hemodialysis, the patient suddenly presented with pulmonary hemorrhage. In this setting, high levels of myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody (ANCA) and negative anti-GBM antibodies were found. Therapy with oral prednisone and cyclophosphamide led to resolution of pulmonary hemorrhage and negativity of MPO-ANCA.- - - - - - - - - - ranking = 5keywords = membrane (Clic here for more details about this article) |
10/125. Periadventitial extracranial vertebral artery hemorrhage in a case of shaken baby syndrome.We report a case of a two-month-old boy who became unresponsive in the sole custody of his father. resuscitation efforts on route to the hospital were able to restore the infant's heart beat. However, neurologic function never recovered. autopsy revealed massive cerebral edema, recent subdural, and subarachnoid hemorrhages, bilateral retinal hemorrhages, and cervical spine ligament hemorrhages. Separation of individual cervical vertebrae showed extensive, bilateral, periadventitial vertebral artery hemorrhages between C1 and C4, with corresponding luminal compression of the vertebral arteries. The importance of this previously unreported phenomena of periadventitial vertebral artery hemorrhage in the setting of shaken baby syndrome is discussed.- - - - - - - - - - ranking = 0.67139690958429keywords = ligament (Clic here for more details about this article) |
