1/11. Intraosseous proliferative sparganosis: a case report and review of the literature.Intraosseous proliferative sparganosis is an extremely rare parasitic disease in which the larvae of incomplete differentiated sparganum proliferate in the human bone. We present the first case of intraosseous proliferative sparganosis arising in the long bone. The patient was a 51-year-old man who complained of a slow growing painful mass on his right leg. The radiographic findings showed an infiltrative osteolytic lesion with speckled calcification at the proximal tibia the clinical diagnosis of which favored chondrosarcoma. Incisional biopsy revealed an innumerable number of small globular shapes, whitish parasites. Histologically, the parasites were composed of a few layers of smooth muscle and several calcerous bodies that were enclosed within a single row of tegumental cells. The latter exhibited a wavy appearance and coated with microvilli. These morphologic findings confirmed the nature of these maldifferentiated larvae. The patient was treated by partial resection of the lesion. This should remind clinicians that parasitic infection of the bone can produce a tumor-like lesion.- - - - - - - - - - ranking = 1keywords = parasitic infection (Clic here for more details about this article) |
2/11. Fournier's gangrene associated with sparganosis in the scrotum.Fournier's gangrene is a necrotizing fasciitis of the scrotum or perineum that may extend by way of the fascial planes to the penis and the anterior abdominal wall up to the clavicles, buttocks, or lower extremities. It is a life-threatening progressive disease that requires aggressive antibiotic therapy and early radical debridement. sparganosis is a parasitic infection that occurs principally in cats and dogs, but human infestations have been reported, albeit rarely. Recently, we experienced a case of Fournier's gangrene associated with sparganosis in the scrotum, which was treated with antibiotics and extensive debridement including removal of a white, flat, shiny sparganum worm.- - - - - - - - - - ranking = 1keywords = parasitic infection (Clic here for more details about this article) |
3/11. sparganosis presenting as a conus medullaris lesion: case report and literature review of the spinal sparganosis.BACKGROUND: sparganosis is a rare parasitic infection affecting various organs, including the central nervous system. In rare cases, sparganosis may involve the spinal cord, usually at the thoracic area. We herein report, to our knowledge, the first case of sparganosis presenting as a conus medullaris lesion and review the literature of sparganosis involving the spinal cord. observation: A 42-year-old man presented with progressive perianal paresthesia and sphincter disturbances. Results of enzyme-linked immunosorbent assay of the cerebrospinal fluid and surgical biopsy were consistent with sparganum infection affecting the conus medullaris. We reviewed 7 other cases of spinal sparganosis. CONCLUSIONS: sparganosis may present as a conus medullaris lesion. This possibility should be considered when clinicians encounter patients with a conus medullaris lesion or cauda equina syndrome with uncertain diagnosis.- - - - - - - - - - ranking = 1.0004171986291keywords = parasitic infection, central nervous system, nervous system (Clic here for more details about this article) |
4/11. sparganum mansoni parasitic infection in the lung showing a nodule.Reported herein is a 57-year-old man infected by sparganum mansoni, a kind of tapeworm, showing a solitary nodule of the middle lobe of the right lung. Because a transbronchial biopsy could not diagnose the nodule, a right middle lobectomy was performed on suspicion of malignant tumor. The lesion was diagnosed as sparganosis by histological and immuno-serological examinations. Histological examination revealed granulomatous inflammation with neutrophil and eosinophil infiltration around the worm and interstitial pneumonia surrounding the nodule. Moreover, vasculitis with foreign body giant cell was seen around the lesion. To the authors' knowledge this is the second case of sparganosis limited in the lung, and the current report presents the first detailed histological description of a pulmonary sparganosis case.- - - - - - - - - - ranking = 4keywords = parasitic infection (Clic here for more details about this article) |
5/11. A case of cerebral sparganosis in south america.Cerebral sparganosis (CS) is a parasitic infection caused by the larva of spirometra mansonoides. Rarely it can affect the human brain. We report the case of a 24-year old man from paraguay who suffered from seizures and headache for one year. A frontal tumor was diagnosed by CT-scan and was subsequently resected. The pathological examination revealed a larva with sparganum characteristics. The evolution of the patient was satisfactory. As far as we know, this is the first case of CS reported in South-America.- - - - - - - - - - ranking = 1keywords = parasitic infection (Clic here for more details about this article) |
6/11. Cerebral sparganosis: case report and review.sparganosis is a rare infection caused by a tapeworm larva from the genus spirometra. A 21-year-old Indian man presented with an 18-month history of episodic confusion followed by a grand mal seizure. Computed tomography and magnetic resonance imaging of the brain confirmed the presence of a lesion of the left occipital lobe. Subsequent stereotactic biopsy revealed a plerocercoid larva or sparganum. Surgical resection resulted in cure. This case prompted a review of the literature on central nervous system sparganosis. Altogether, 17 other cases of primary cerebral sparganosis have been reported previously. seizures, headache, and focal neurologic signs are common at presentation. Neuroradiologic imaging is sensitive but not specific for the identification of lesions. enzyme-linked immunosorbent assay of cerebrospinal fluid or serum may be diagnostically helpful. However, the diagnosis is generally made after surgical resection, which is usually curative.- - - - - - - - - - ranking = 0.00041719862906184keywords = central nervous system, nervous system (Clic here for more details about this article) |
7/11. Cerebral sparganosis. Case report.The tapeworm spirometra mansonoides infects man worldwide, particularly in Asian countries. Rarely, the central nervous system is involved; such a case is presented here. In the total of 12 reported cases, including the case described, the worm presented clinically as a mass suspicious for neoplasm or chronic abscess cavity. Surgical removal was invariably curative in each case. Although infrequent, the possibility of tapeworm infection should be entertained in the evaluation of intracranial masses in patients who have visited exotic locales.- - - - - - - - - - ranking = 0.00041719862906184keywords = central nervous system, nervous system (Clic here for more details about this article) |
8/11. sparganosis of the brain. Case report.A rare case of cerebral sparganosis occurring in a 7-year-old boy is reported. Since his clinical symptoms fluctuated and diagnostic evaluation demonstrated multiple lesions, he was examined for a parasitic infection. Emphasis is placed on the difficulties involved in diagnosing cerebral sparganosis.- - - - - - - - - - ranking = 1keywords = parasitic infection (Clic here for more details about this article) |
9/11. Cerebral sparganosis in an East Timorese refugee.OBJECTIVE: To report the first case of cerebral sparganosis diagnosed in australia. CLINICAL FEATURES: A 23-year-old East Timorese refugee, whose diet before migration included raw snakes and frogs, presented with a generalised tonic-clonic seizure and a nine-month history of episodic left hemianaesthesia. Computerised axial tomography of the brain showed a right frontal lesion, which was excised, and histological examination demonstrated changes typical of sparganosis. INTERVENTION AND OUTCOME: Excision of the lesion resulted in cure. Postoperative eosinophilia and a subcutaneous nodule presumed to be due to disseminated sparganosis resolved following a course of praziquantel. CONCLUSION: Clinicians should consider the possibility of unusual parasitic infections in refugees who present with intracranial space-occupying lesions, especially those from developing countries. A dietary history may aid the diagnosis.- - - - - - - - - - ranking = 1keywords = parasitic infection (Clic here for more details about this article) |
10/11. Cerebral sparganosis diagnosed and treated with stereotactic techniques. Report of two cases.Infestation of the central nervous system with sparganum, the larva of spirometra mansoni, is rare. Only 27 cases have been reported in the literature; however, the true incidence might be underestimated. Two cases are reported that were definitively diagnosed by stereotactic biopsy techniques. Without a positive histological diagnosis, the first case would have been diagnosed as having a metastatic brain tumor and a course of radiotherapy would probably have been initiated. Differentiation between granuloma of cerebral sparganosis and brain tumors such as meningiomas, gliomas, and metastatic tumors is often difficult before operation. Detailed magnetic resonance imaging might offer some help in such cases. Emphasis is placed on the increasing importance of stereotactic surgery in the diagnosis and treatment of an intracerebral mass lesion, including cerebral sparganosis.- - - - - - - - - - ranking = 0.00041719862906184keywords = central nervous system, nervous system (Clic here for more details about this article) |
