1/62. Papillary endothelial hyperplasia presenting as a chest wall neoplasm.Soft tissue hematomas generally resolve but may persist and develop into slow-growing, organized masses. These chronic expanding hematomas are characterized by a pseudocapsule and a predominantly necrotic central cavity, with foci of newly formed capillaries. These have been called chronic expanding hematomas or Masson's papillary endothelial hyperplasia. These lesions can mimic vascular neoplasms and must be considered in the evaluation of expanding soft tissue vascular malformations.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/62. Emergency tracheostomy following life-threatening hemorrhage in the floor of the mouth during immediate implant placement in the mandibular canine region.BACKGROUND: The edentulous interforaminal mandibular area is frequently the preferred area for implant placement. methods: A case of emergency tracheostomy following life-threatening hemorrhage in the floor of the mouth during immediate implant placement in the mandibular canine region is described. The probable cause was bleeding from the sublingual artery or a branch of that artery following implant perforation of the lingual cortex. RESULTS: Healing was uneventful and the patient was released from the hospital after 11 days. Three years later, CT showed a well-osseointegrated implant with a severe buccolingual inclination. CONCLUSIONS: It is stressed that short implants (14 mm or less) should be used in the mandibular canine region and that effective treatment of this complication is essential.- - - - - - - - - - ranking = 7.690090029668keywords = mouth (Clic here for more details about this article) |
3/62. Endoscopic and radiological features of intramural esophageal dissection.A 41-year-old woman was admitted to our hospital complaining of chest pain, dysphagia, and odynophagia after an upper respiratory tract infection and nasogastric tube insertion. An upper endoscopy showed a large submucosal bulge along the posterior wall from the upper esophagus with mucosal tears and bridge formation, extending down to the lower esophagus. A barium esophagogram revealed a "double-barreled" esophagus, and chest computed tomography (CT) scan showed eccentric thickening of the esophageal wall. The diagnosis of intramural esophageal dissection (IED) was made and the patient was managed conservatively with nothing by mouth and intravenous hydration. The clinical course was uneventful; the patient was discharged later and up to the time of writing has been completely asymptomatic, with normal swallowing function.- - - - - - - - - - ranking = 1.5380180059336keywords = mouth (Clic here for more details about this article) |
4/62. Signs of medullar aplasia in the oral cavity: report of case.Medullar aplasia is a hematological disease characterized by medullar dysfunction that results in a marked decrease of various hematological cellular elements. This produces anemia, infections of different etiologies and also, spontaneous or provoked hemorrhagic syndromes of varying importance. A case of medullar aplasia affecting a child, diagnosed after a tooth extraction is reported, and accompanied by its pathological characteristics. In addition, an easy reading E.L.I.S.A/ test for diagnosing herpes virus type 1 or 2 is presented.- - - - - - - - - - ranking = 4keywords = cavity (Clic here for more details about this article) |
5/62. Extrapericardial cardiac tamponade caused by traumatic retrosternal hematoma.cardiac tamponade is an uncommon complication of blunt chest trauma, resulting typically from hemorrhage into the pericardial space. We report a case of hemodynamic compromise secondary to an extrapericardial compression caused by the acute formation of a retrosternal hematoma associated with a sternal fracture. The patient was involved in a violent deceleration accident. Initially, he only complained of an anterior thoracic pain, but subsequently became restless, pale, and dyspneic. A severe hypotension associated with sinus bradycardia (45 bpm) rapidly occurred. Both jugular veins became markedly turgescent, but no significant pulsus paradoxus was noted. echocardiography disclosed a large hematoma, compressing anteriorly both the right ventricular cavity and outflow tract. Surgical evacuation of the retrosternal hematoma related to a bifocal fracture of the manubrium was followed by instantaneous hemodynamic improvement. Regional extrapericardial tamponade secondary to the acute formation of compressive retrosternal hematoma is an unusual cause of circulatory failure after severe blunt chest trauma. Since conventional clinical signs associated with typical tamponade physiology may be lacking in this setting, echocardiography is ideally suited for early recognition of this unusual condition.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
6/62. Explosion of a vulvar hematoma during spontaneous vaginal delivery. A case report.BACKGROUND: Vulvar hematoma formation during a spontaneous vaginal birth is rare. Although conservative management or observation is an option, complications, including delivery obstruction and excessive vaginal bleeding, may occur. CASE: A woman presented in active labor with an enlarging vulvar hematoma reaching the size of a softball. Spontaneous vaginal delivery occurred with an "explosion" of the hematoma and excessive blood loss. To obtain hemostasis, the hematoma cavity was explored and the bleeding points sutured. CONCLUSION: With a large intrapartum vulvar hematoma, the risk of rupture exists. If it occurs, delivery should be accomplished expediently, hemostasis achieved rapidly and blood loss monitored closely.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
7/62. Planned two-step vitrectomy for extremely large and thick subretinal hematoma.PURPOSE: To describe a new surgical strategy, planned two-step vitrectomy, for a large and thick subretinal hematoma involving 3 or more quadrants of the fundus. SURGICAL methods: In a first-step vitrectomy, a retinotomy was made in the posterior pole, after any vitreous hemorrhage had been removed. Following fluid-gas exchange with no laser photocoagulation around the retinotomy, patients took a face-down position for a few days to a week to facilitate subretinal hemorrhage movement to the vitreous cavity and anterior chamber. In a second-step surgery, the hemorrhage in the vitreous cavity and anterior chamber was washed out. The remaining subretinal hemorrhage was aspirated, and the retina was reattached with fluid-gas exchange and laser photocoagulation around the retinotomy. RESULTS: The planned two-step vitrectomy was performed in 4 consecutive patients with large and thick subretinal hematomas involving 3 or more quadrants seen during a 3-year period. By a face-down position after the first-step vitrectomy, subretinal hemorrhage moved to the vitreous cavity and anterior chamber. The remaining subretinal hemorrhage in a smaller quantity could be easily removed, leading to retinal reattachment in the second-step surgery. CONCLUSIONS: The planned two-step vitrectomy is a safer and more effective procedure for removing a large quantity of subretinal hemorrhage in a shorter period of surgical time, compared with hemorrhage removal in a single vitrectomy.- - - - - - - - - - ranking = 3keywords = cavity (Clic here for more details about this article) |
8/62. Ruptured epidermoid cyst and haematoma of spleen: a diagnostic clue of high levels of serum carcinoembryonic antigen, carbohydrate antigen 19-9 and Sialyl Lewis x.Splenic epidermoid cyst is a rare disease and that with haematoma is even more rare. The case of epidermoid cyst of the spleen is described, in a 36-year-old Japanese female, manifesting as left hypochondralgia and rupture of the cyst. Clinical features were splenic lesion 14 cm in diameter and consisting of round-hypovascular and crescent-hypervascular sublesions. Extravasation of cystic fluid was detected in abdominal cavity Preoperative diagnosis was difficult due to such uncommon features, however high levels of serum tumour markers (carcinoembryonic antigen, carbohydrate antigen 19-9, Sialyl Lewis x) strongly suggested epidermoid cyst. Laparotomic splenectomy and cholecystectomy were performed for splenic lesion and gallstones, and serum tumour markers decreased following surgery. Pathological diagnosis of the round-hypovascular lesion was epidermoid cyst and crescent-hypervascular lesion was haemorrhage (haematoma).- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/62. Successful laparoscopic treatment of a ruptured primary ovarian pregnancy.A 26-year-old woman had classic symptoms of primary ovarian pregnancy. Ultrasound examination disclosed a cystic mass surrounded by a complex mass that was compatible with hematoma in the pouch of Douglas, as well as an intrauterine device (IUD) displaced near the isthmic portion of the uterine cavity. laparoscopy revealed a ruptured gestational sac in the cul-de-sac that was encapsulated by a hematoma originating from the right ovary. All deep-seated products of conception were excised from the ovary, and the IUD was removed. Treatment was successful and avoided more invasive intervention.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/62. Intracavitary hematoma simulating mycetoma formation.SUMMARY: This case report details the initial radiographic findings of a patient with mixed connective-tissue disease who presented with significant hemoptysis. Several radiographic findings suggested mycetoma formation, prompting appropriate antibiotic therapy; however, the rapid resolution and subsequent reappearance of the lesion on serial images pointed toward a diagnosis of hemorrhage into a preexisting cavity. Chest radiographic and computed tomographic findings commonly described as pathognomonic for the diagnosis of mycetoma are, in fact, nonspecific and can be simulated by several other entities that result in intracavitary masses. Familiarity with these radiographic "mimickers" of mycetoma will aid in avoiding misdiagnosis and unnecessary or improper invasive interventions when the appropriate clinical history and course of disease are appreciated.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
