1/135. Systemic infection with Alaria americana (trematoda).Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.- - - - - - - - - - ranking = 1keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
2/135. Renal granulomatous sarcoidosis in childhood: a report of 11 cases and a review of the literature.We analysed retrospectively 11 children with renal granulomatous sarcoidosis confirmed by renal histology in order to describe the course and prognosis of the disease. Symptomatic sarcoidosis was diagnosed at a mean age of 10.1 years. Nine children had renal involvement at the time of diagnosis. In the course of the disease, nine patients developed renal failure and mild proteinuria, seven had transient sterile leukocyturia, four showed microscopic haematuria, seven had a urinary concentrating defect, and enlarged kidneys were seen in three patients. One child had hypercalcaemia and hypercalciuria, none had hypertension. light microscopy of the kidney showed interstitial infiltration by mononuclear cells in all children, interstitial fibrosis in nine patients, epithelioid granulomas in seven, tubular involvement in eight, and mild glomerular involvement in seven patients. Renal immunofluorescence was negative. Ten children received prednisone for 1-11 years. After a mean follow up of 5.5 years, three patients had entered end-stage renal failure and one had chronic insufficiency after interruption of medical supervision and prednisone therapy. CONCLUSION: Renal failure, proteinuria, leukocyturia, haematuria, and concentration defect are the prominent features of renal granulomatous sarcoidosis in children. Steroid therapy, adjusted according to disease activity, may prevent end-stage renal failure.- - - - - - - - - - ranking = 0.094443591844236keywords = cord (Clic here for more details about this article) |
3/135. Spinal aspergillus abscess in a patient with bronchocentric granulomatosis.aspergillus fumigatus hyphae is often found in the lung tissue of patients with bronchocentric granulomatosis (BCG). This organism is believed to be one agent responsible for inciting the hypersensitivity response and subsequent development of the characteristic pathology that defines BCG. The definitive etiology of this disease, however, remains conjectural. Corticosteroids represent the mainstay of therapy. The fungi recovered from patients with BCG are considered noninvasive; thus, the risk of fungal invasion secondary to steroid-induced immunosuppression is believed to be negligible. However, we report a case of spinal aspergillus abscess that developed in a patient with BCG subsequent to steroid therapy. This case also highlights the necessity for aggressive medical and neurosurgical intervention to avert the development of neurological sequelae.- - - - - - - - - - ranking = 0.27488208707123keywords = spinal (Clic here for more details about this article) |
4/135. Systemic bartonella henselae infection with hepatosplenic involvement.BACKGROUND: Systemic manifestations of bartonella henselae infection are rare in the immunocompetent host. The infection generally has initial symptoms of prolonged fever and multiple granulomatous lesions in liver and spleen. methods: Retrospective analysis of the records of all patients with hypoechogenic lesions in the liver and/or spleen diagnosed from 1990 through 1996 in three pediatric clinics in northern italy. RESULTS: Among the 13 patients reviewed, 9 had evidence of B. henselae infection and hepatosplenic involvement: five had prolonged and unexplained fever lasting from 3 to 16 weeks, and four had typical cat-scratch disease and peripheral lymphadenitis. All patients had increased sedimentation rate and normal aminotransferase serum activity. Five children had a liver biopsy, by laparotomy in three and by needle in two. In all, the predominant liver lesion was a necrotizing granuloma. All patients were treated with broad-spectrum antibiotics. fever lasted from 3 to 16 weeks, and hepatic and splenic lesions resolved in all with residual splenic calcification in one. CONCLUSIONS: Systemic B. henselae infection represents an important cause of inflammatory hypoechogenic hepatosplenic lesions in children. serology provides rapid diagnosis, avoiding multiple and invasive investigations. Hepatosplenic involvement can be found even in children with typical cat-scratch disease without apparent systemic manifestations. The frequency of liver and/or splenic involvement in cat-scratch disease is probably underestimated.- - - - - - - - - - ranking = 0.094443591844236keywords = cord (Clic here for more details about this article) |
5/135. 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 = 0.27488208707123keywords = spinal (Clic here for more details about this article) |
6/135. Interstitial granulomatous dermatitis with plaques.We report on the clinical and histopathologic findings of four patients who had asymptomatic, erythematous to violaceous plaques symmetrically distributed on the upper aspect of the thighs, lateral chest, and in two cases also on the abdomen and flexor surface of the elbows. All of the patients were women; two of them had arthritis, which in one case was associated with an autoimmune disorder, and another had autoimmune thyroiditis. Histopathologically, all cases showed similar changes consisting of an interstitial granulomatous dermatitis involving mostly the lower reticular dermis. histiocytes were the predominant cellular component, arranged interstitially and in small palisades around foci of degenerated collagen bundles in concert with large numbers of neutrophils and eosinophils. Interstitial granulomatous dermatitis can present different clinical expressions, including linear cords, papules, and, as in our cases, plaques. This peculiar histopathologic pattern falls into the spectrum of cutaneous extravascular necrotizing granuloma, a condition that is often associated with systemic autoimmune disease.- - - - - - - - - - ranking = 0.094443591844236keywords = cord (Clic here for more details about this article) |
7/135. Epidural Bilharzioma mansoni compressing the spinal cord: case report.A case of an epidural Bilharzioma mansoni (epidural granuloma due to Schistosoma mansoni) compressing the spinal cord at T11-T12 is presented. The patient, a 20-year old African man, started complaining of recurrent back pain since 1993 and became paraparetic in 1996. The myelography showed a complete block at T12 and the CT scan showed a mass at T11-T12 compressing the spinal cord. Through a bilateral laminectomy of T 10, T11 and T12, the bilharzioma was completely removed. The histopathology and the laboratory tests confirmed the diagnosis of granuloma due to schistosoma mansoni. The patient recovered completely and was seen last time more than one year after surgery. Not a similar case has been found in the literature and the authors presume that this is the first case ever successfully treated by surgery and chemotherapy and reported in the world literature.- - - - - - - - - - ranking = 6keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
8/135. Medically treated intraspinal "brucella" granuloma.BACKGROUND: Although there have been reports of brucella granuloma or abscess in the literature, they were all localized extradurally except one, and most patients underwent surgery. CASE REPORT: A 40-year-old female presented with urinary and fecal incontinence and a two-month history of progressive weakness of the right leg and numbness of the left leg. Four months previously, she had been diagnosed with systemic brucellosis with a period of radiculomeningoencephalitis; she was treated successfully with rifampicin, doxycycline, trimethoprim/sulfamethoxazole (TMP/SMZ), and streptomycin, and was discharged symptom-free on rifampicin and doxycycline. Neurological examination revealed spastic paraparesis, globally hyperactive deep tendon reflexes (DTRs) and sensory level at T6. magnetic resonance imaging (MRI) of the spinal cord revealed a 10 x 30 mm intradural-intramedullary mass lesion at the T5 level with surrounding edema that enhanced with contrast. The cerebrospinal fluid (CSF) was xanthochromic with lymphocytic pleocytosis and elevated levels of albumin, immunoglobulins, and antibody titers for brucella. The medications were modified to rifampicin 1200 mg, doxycycline 400 mg, and TMP/SMZ 480/2400 mg daily, and methylprednisolone 100 mg in decremental doses (for 6 weeks). After 2 months, the patient was almost symptom-free and her medication doses were decreased. After 5 months, the mass lesion resolved almost completely. The treatment was discontinued after 2 years. CONCLUSIONS: The case is presented because of its uniqueness. In cases of brucella granuloma, the authors recommend a trial of medical treatment with adequate dosages for a reasonable length of time before considering surgical intervention.- - - - - - - - - - ranking = 2.3744104353561keywords = spinal cord, spinal, cord (Clic here for more details about this article) |
9/135. granulomatous mastitis.granulomatous mastitis is a benign mammary lesion, which clinically can closely simulate breast cancer. The condition has only recently been recognized, less than a dozen cases being recorded in the English literature. Two further cases are presented, the histological features are illustrated, and the literature is reviewed.- - - - - - - - - - ranking = 0.094443591844236keywords = cord (Clic here for more details about this article) |
10/135. Spinal aspergillosis in nonimmunocompromised host mimicking Pott's paraplegia.The aim of this report is to highlight the less-known aspergillus spondylitis (AS) that may completely mimic Pott's paraplegia, leading to occasional but expensive diagnostic error, as the chemotherapeutic management of the two is different. A case of a patient with the diagnosis of Pott's paraplegia who turned out to have aspergillus spondylitis is described. Issues and difficulties regarding the differentiation between these two forms of spine infection and their therapeutic implications are discussed. We conclude that differential diagnosis of spinal tuberculosis (TB) should include aspergillus spondylitis, as cure of spinal aspergillosis, especially in early stages, is possible with surgery and/or antifungal agents, and morbidity and mortality are high in neglected cases.- - - - - - - - - - ranking = 0.54976417414246keywords = spinal (Clic here for more details about this article) |
