11/773. Adrenal endothelial cyst with massive central calcification.A 55-year-old woman was treated for a rare case of adrenal endothelial cyst that was detected incidentally during management of abdominal pain. Computed tomography of the tumor displayed massive central calcification and a fluid-fluid level by intracystic hemorrhage. magnetic resonance imaging showed an intracystic papillary part with calcification. After surgery, the tumor was diagnosed as an angiomatous type of adrenal endothelial cyst.- - - - - - - - - - ranking = 1keywords = abdominal pain, pain (Clic here for more details about this article) |
12/773. Regional proliferation of HMB-45-positive clear cells of the lung with lymphangioleiomyomatosislike distribution, replacing the lobes with multiple cysts and a nodule.The authors report a case of a localized lesion of the lung presenting as multiple cysts and as a tumor in the right upper and middle lobes, consisting of a diffuse proliferation of clear cells with intralysosomal glycogen granules and human melanin black (HMB)-45 immunoreactivity. A 33-year-old woman complained of dyspnea because of the enlargement of bullae in the right upper and middle lung fields without stigmata of tuberous sclerosis. Resection showed multiple, various-size air-filled cysts and a tumor. The cysts in the resected lungs were reminiscent of lymphangioleiomyomatosis (LAM), accompanied by the diffuse proliferation of clear cells in the interstitium. The tumor, 1.8 cm in diameter, resembled a clear cell tumor of the lung (CCTL) and showed proliferation of clear cells with sinusoidlike vascular spaces. Both forms of proliferation were continuous spatially, and both constituent cells showed diffuse HMB-45 immunoreactivity. The cells that comprised a nodule revealed ultrastructurally abundant cytoplasmic glycogen, which was in the form of free and membrane-bound glycogen granules. This case may represent a particular pulmonary lesion consisting of CCTL-LAM hybrid cells, which share the cytologic features with CCTL cells on one hand, and the proliferative pattern and potential with LAM cells on the other.- - - - - - - - - - ranking = 0.16234509944454keywords = upper (Clic here for more details about this article) |
13/773. Pyrofluid inhalation in "fire-eaters": sequential findings on CT.We report the sequential computed tomography (CT) findings in two fire-eaters after accidental inhalation of pyrofluid. The initial chest radiographic findings were ambiguous and the interpretation of the radiographs was biased by clinical history unrelated to fire eating. On CT, pneumatoceles were the major findings in both patients. The pneumatoceles resolved rapidly, leaving only minimal scarring. Our cases illustrate the sequential evolution of pneumatoceles in fire-eaters after the inhalation of pyrofluid and documents the rapidity with which the lesions regress. The rare accidental inhalation of pyrofluid in fire-eaters may produce a puzzling clinical and radiographic picture and can be confused with other lung disorders.- - - - - - - - - - ranking = 0.058398143426185keywords = chest (Clic here for more details about this article) |
14/773. Unusual findings in the inguinal canal: a report of four cases.Masses in the inguinal canal other than hernias are rare occurrences, and their preoperative diagnosis requires a high index of suspicion. A soft, partly reducible groin mass in a 3-month-old boy proved to be a cystic lymphangioma within the inguinal canal. A 15-month-old female who presented with an irreducible inguinal mass was found to have a neuroblastoma metastasis in the groin. An irreducible groin mass in a 6-year-old female proved to be an inguinal canal epidermal inclusion cyst. A 14-year-old female presented with a painful groin swelling that represented an incarcerated hemorrhagic ovarian cyst. An awareness of the wide spectrum of entities other than the standard bowel, testicle, and ovary in the inguinal canal can help to identify uncommon pathologies preoperatively.- - - - - - - - - - ranking = 0.28581588631759keywords = pain (Clic here for more details about this article) |
15/773. Familial fatal and near-fatal third ventricle colloid cysts.BACKGROUND: Despite having a presumed congenital origin, familial cases of colloid cysts have been reported only rarely. The first case of a brother and sister with colloid cysts is reported here, and the relevant literature is reviewed. methods: A 25-year-old man presented with a 24-h history of headache and vomiting. He rapidly became unconscious and fulfilled the criteria for brain death on arrival at hospital. No surgical intervention was performed. RESULTS: The patient's sister presented at the age of 41 with headaches and rapidly became unconscious. The sister had urgent bilateral ventriculostomies. followed by transcallosal removal of a colloid cyst. CONCLUSIONS: These cases support the hypothesis that colloid cysts are congenital lesions and provide some evidence of a possible genetic predisposition to their formation. Sudden death remains a real risk for patients harbouring a colloid cyst.- - - - - - - - - - ranking = 0.65127391010709keywords = headache (Clic here for more details about this article) |
16/773. Endoscopic treatment of symptomatic septum pellucidum cysts: with some preliminary observations on the ultrastructure of the cyst wall: two technical case reports.OBJECTIVE AND IMPORTANCE: We describe two patients with symptomatic septum pellucidum cysts managed by endoscopic fenestration. In each case, tissue from the cyst wall was studied to define the origin of the cyst wall and fluid. CLINICAL PRESENTATION: The patients, a 6-year-old boy and a 42-year-old man, each presented with headaches and a syncopal episode. Imaging studies demonstrated large septum pellucidum cysts with obstruction of the foramina of Monro. INTERVENTION: The patients underwent endoscopic transventricular cyst fenestration with a 4-mm steerable fiberscope. The fenestrations were created to allow communication with the right and left lateral ventricles. In one patient, adhesions between the cyst wall and the foramen of Monro were lysed with endoscopic monopolar cautery. Tissue from the cyst walls was removed for examination by electron microscopy. Postoperatively, the headaches and syncopal episodes resolved in both patients. CONCLUSION: Endoscopic fenestration of symptomatic septum pellucidum cysts produces immediate relief of the mass effect of the cyst and resolution of associated symptoms. Cannulation of the lateral ventricle before cyst fenestration prevents inadvertent injury to the fornices, thalamus, internal capsule, caudate nucleus, and septal and thalamostriate veins. The endoscopic approach allows the surgeon to ensure communication within the ventricular system, thus avoiding placement of a shunt. Preliminary ultrastructural analysis indicates that the cyst walls derive from the septum pellucidum rather than the choroid plexus or arachnoid. The cellular machinery necessary for fluid secretion was identified in some specimens.- - - - - - - - - - ranking = 0.65127391010709keywords = headache (Clic here for more details about this article) |
17/773. Testicular cystic dysplasia: evaluation of 3 new cases treated without surgery.PURPOSE: We describe 3 cases of testicular cystic dysplasia that were diagnosed only by sonography to avoid an invasive approach. MATERIALS AND methods: Three patients 5, 8 and 12 years old, respectively, had increased testicular volume and/or intermittent pain. Sonographic examination of the testis by high frequency (7.5 mHz.) probes showed the typical onset of testicular cystic dysplasia, characterized by several small focal or diffuse intraparenchymal cystic formations. RESULTS: biopsy or orchiectomy was not considered. At 16, 18 and 24 months of followup, respectively, testicular pain was absent in our 3 cases and sonographic findings were unchanged. CONCLUSIONS: Clinical and sonographic followup is considered sufficient to evaluate possible changes in the clinical course of this pathological condition which, although benign, still remains to be defined.- - - - - - - - - - ranking = 0.57163177263518keywords = pain (Clic here for more details about this article) |
18/773. Testicular cysts: management and literature review.Simple testicular cysts are extremely rare; only 20 cases have been reported in the literature. Sites include the tunica albuginea, tunica vaginalis, and testicular epidermis. Conservative enucleation is an effective treatment for these lesions once ultrasound examination establishes that the mass is cystic. Such Enucleation salvages testicular tissue. In the cases discussed, two patients were initially evaluated for vague testicular discomfort and one patient for male infertility. All were subsequently found to have benign testicular cysts. All the cysts were excised, and all patients remain disease-free. Included is a case series report of simple testicular cysts and a review of the literature.- - - - - - - - - - ranking = 1.5580423690268keywords = discomfort (Clic here for more details about this article) |
19/773. Intracerebral cyst associated with meningioma.A 27-year-old male had experienced an episode of severe headache and nausea, sometimes accompanied by an inability to name objects. magnetic resonance imaging showed a huge cyst within the left temporal lobe and a high degree of brain shift by it. A small round mass, which appeared to be a mural nodule, was located in the tip of left middle fossa. It was highly enhancing together with its attached dura mater, but the cyst wall was not enhanced. Sphenoid ridge meningioma with an associated intracerebral cyst or cystic glioma invading the dura mater was suspected. During surgery the small tumor was found to be arising from the sphenoid ridge and evaginating into the tip of the temporal lobe. The intracerebral cyst had a smooth surface and the tumor was visible outside the cyst through its wall. The tumor was totally removed, but the cyst wall was left without excision. Postoperatively he had no symptoms. Histological examination showed a microcystic meningioma. It is stressed that differentiations of cystic meningiomas from other cystic tumors and, of intratumoral from extratumoral cystic meningiomas using radiological, operative or histological findings are important.- - - - - - - - - - ranking = 0.32563695505355keywords = headache (Clic here for more details about this article) |
20/773. Successful surgical treatment of haemophilic pseudotumour, filling the defect with hydroxyapatite.A preliminary report is made on the use of hydroxyapatite for surgical procedure of pseudotumour, a rare but serious complication of the bleeding diathesis in patients with inherited bleeding disorders. Surgical or percutaneous treatment and refilling with fibrin sealant is shown to be a successful therapy in a 19-year-old male with severe haemophilia B. The pseudotumour, in the upper pad of the left leg, was filled with hydroxyapatite after surgery. We suggest that the use of hydroxyapatite is a new and useful option in the surgical treatment of haemophilic pseudotumour.- - - - - - - - - - ranking = 0.081172549722272keywords = upper (Clic here for more details about this article) |
