Multifocal osteolytic lesions of the skull: a primary cavernous hemangioma mimicking a neoplastic invasive lesion.
ABSTRACT: Intraosseous cavernous hemangioma is a rare cause of osteolytic lesions of the skull, and its multifocal type is even more infrequent. This tumor is difficult to accurately diagnose by imaging and can be confused with osteolytic Langerhan's cell histiocytosis or other neoplasms. Here we present a case of multifocal intraosseous cavernous hemangioma of the skull treated with surgical intervention in our hospital five years ago. A review of related literatures and case reports is also provided to help clarify the diagnosis and devise treatment regimens. In light of the difficulties of early diagnosis, early en bloc surgical removal is recommended.
Project description:To present an overview of varied clinical presentations, investigations and treatment options for Osteolytic skull lesions.It is a prospective study.We conducted this study from January 2013 to December 2015 in the Department of Neurosurgery, Nil Ratan Sircar Medical College and Hospital, Kolkata. During this period, 14 patients presented with osteolytic skull lesions through the outpatient department. All patients were thoroughly investigated with appropriate hematological and radiological investigations and treated following admission, and surgery was performed in the Neurosurgery Department. All were followed regularly in OPD.Total 14 patients were included in the study. Amongst these 7 were male and 7 female. Age group of patients ranged from 5 to 72 years. Of 14 cases, three cases had dermoid cyst, four cases had metastasis, and one each case had epidermoid cyst, intradiploic meningioma, benign cystic lesion, tuberculosis, histiocytosis X, hemangioma, and osteomyelitis. All underwent diagnostic/therapeutic procedures and referred for Radio or chemotherapy where indicated.All scalp/skull lesions need careful clinical correlation, appropriate radiological investigations to establish diagnosis and subject them to suitable treatment.
Project description:BACKGROUND:Primary intraosseous meningioma is a subset of extradural meningioma that arises in the bone, and only a few cases have been reported to date. CASE PRESENTATION:An 80-year-old man presented with decreased hearing on the right side accompanied by a disturbance of balance 10?months prior to admission. Magnetic resonance imaging revealed an 8?×?7?cm osteolytic mass in the right posterior fossa related to the petrous bone, with extension to the cervical region. During surgery, the tumor was found to be located extradurally, with no invasion of the dura. The tumor was removed entirely, apart from a small portion around the jugular foramen to avoid lower cranial nerve injury. CONCLUSION:The final diagnosis was primary intraosseous osteolytic meningioma with atypical pathology. Here, we report a rare case of an osteolytic skull lesion in the skull base not invading the dura and with extensive bone destruction.
Project description:BACKGROUND: Cavernous hemangioma are the most common benign lesions of the orbit. Their surgical resection is still challenging and several surgical approaches have been proposed. CASE DESCRIPTION: We present the case of a 59-year-old woman with a cavernous hemangioma of the orbital apex, which was diagnosed incidentally. The hemangioma was extraconal and involved mainly the medial orbital apex; it also extended to the pterygoid fossa, to the middle fossa, to the maxillary and sphenoid sinuses. The surgical resection was performed by a pure endoscopic transphenoidal, transmaxillary, transethmoidal approach, achieving a total removal. The patient had a transient and incomplete paresis of the VI cranial nerve on the left side and did not experience other postoperative complications. CONCLUSION: The endoscopic endonasal approach proved successful in the management of this case and it should be considered in the surgical management of extraconal orbital apex lesions with medial or inferior extension.
Project description:Introduction:Hemangioma is a common benign tumor of blood vessels, that rarely develops in the oropharynx. Cavernous hemangioma is characterized by thin-walled dilated blood vessels lined with endothelial cells. Case report:We report a case of a 46 years-old woman who was admitted to our department with a complaint of chronic dysphonia and dysphagia. Clinical examination, radiological investigations and thyroid scintigraphy found a mass of the tongue base, compatible with a lingual thyroid. Treatment consisted of surgical excision through a cervical approach. The histopathological examination found a cavernous hemangioma. Conclusion:Though hemangioma is very rare in the base of tongue, it should be a part of the differential diagnosis while investigating a lesion in the oral cavity and the oropharynx, alongside the other possibilities.
Project description:Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up.
Project description:Cavernous hemangioma (CH) of the thymus is an extremely rare congenital venous malformation. Related symptoms are non-specific and patients are often asymptomatic. The diagnosis is difficult to make either by non-invasive or mini-invasive procedures. Surgical resection is usually required for diagnosis and treatment. We report a case of a 46-year-old men with an incidental finding of an anterior mediastinal tissue mass on chest computed tomography scan. A complete surgical resection of the mass was performed. Histopathological examination concluded to a thymic CH.
Project description:We report an unusual presentation of an orbital cavernous hemangioma in a 26-year-old female, who noted sudden redness and swelling of the left eye (LE) on waking up. At presentation, upper eyelid edema with periorbital ecchymosis and subconjunctival hemorrhage were noted in the LE. Although there was transient symptomatic relief with topical medications, blurring of vision developed in the LE. When seen 10 days later, the patient's LE showed axial proptosis. Magnetic resonance imaging revealed an intraconal soft tissue mass in the superomedial quadrant of the left orbit. Superior orbitotomy with mass excision was done; histopathological examination of the excised mass revealed a cavernous hemangioma. The patient had complete visual recovery following surgery. To our knowledge, an acute presentation of an orbital cavernous hemangioma with subconjunctival hemorrhage and periorbital ecchymosis has not previously been reported.
Project description:INTRODUCTION: Liver cavernous hemangioma is the most common noncystic hepatic lesion, and a hemangioma that undergoes degeneration and fibrous replacement is called a hepatic sclerosed hemangioma. CASE PRESENTATION: A 63-year-old Japanese man was admitted for detailed investigation of a liver tumor. Tumor markers carcinoembryonic antigen, alpha-fetoprotein, and CA19-9 levels in the peripheral blood were not elevated at any time. Plain computed tomography showed an approximately 1.5 cm low density mass in the periphery of segment 8, which was marginally enhanced on contrast-enhanced dynamic computed tomography. On magnetic resonance imaging, the tumor was hypointense on T1-weighted image and hyperintense on T2-weighted image. The tumor was suspected to be an atypical hemangioma, metastatic, hepatocellular carcinoma, or cholangiocellular carcinoma. Segmental hepatectomy was performed. Histological examination of the resected tumor specimen revealed a sclerosed hemangioma with marked hyalinization and sparse stromal fibrosis. Immunochemically, the tumor cells were positive for CD34 and alpha smooth muscle actin. Electron microscopically, the residual hemangioma consisted of numerous caveolae and vesicles in endothelial cells in irregular shapes and sizes. Immunostaining for caveolin-1 showed decreased or no caveolin-1 reactivity in the hyalinized lesions of the sclerosed hemangioma, but abundant caveolin-1 reactivity in the residual cavernous hemangioma. Of interest, computed tomography images of the tumor obtained 10 years earlier at our hospital depicted a 3 cm typical cavernous hemangioma. CONCLUSIONS: Hepatic sclerosed hemangioma is a rare condition. Comparison of radiological findings of the lesion over a period of 10 years was valuable in providing insight for the evolutional process from liver cavernous hemangioma to hepatic sclerosed hemangioma.
Project description:Epithelioid hemangioma of bone is a rare vascular neoplasm with a ubiquitous distribution. To date, up to 25% epithelioid hemangioma of bone presents synchronous bone lesions. We report a unique case of epithelioid hemangioma with multifocal metachronous bone lesions without any fatal outcome observed after a long period. Importantly, a strong nuclear expression of FOSB antibody was detected by immunohistochemical analysis. In this case, the pathologic and radiologic findings are also described. We suggest that epithelioid hemangioma can present multifocal metachronous bone lesions without producing a fatal outcome.
Project description:Backgrounds/Aims:While minimal invasive surgery has become popular, the feasibility of laparoscopy for liver cavernous hemangioma has not been shown. Methods:Patients who underwent hepatectomy for liver cavernous hemangioma from January 2008 to February 2019 at the Samsung Medical Center were reviewed. Patients who underwent trisectionectomy were excluded. Background characteristics, along with operative and postoperative recovery, were compared between the laparoscopy and open surgery groups. Results:Forty-three patients in the laparoscopy group and 33 patients in the open surgery group were compared. The differences in the background characteristics were presence of symptoms (14.6% in laparoscopy vs. 57.1% in open, p<0.001) and tumor location (right, left and both side p=0.017). The laparoscopy group had smaller blood loss (p=0.001), lesser blood transfusion requirements (p=0.035), lower level of post-operative total bilirubin, prothrombin time (INR) (p=0.001, 0.003 each), shorter hospital stay (p=0.001), earlier soft diet start (p<0.001), earlier drain removal (p<0.001) and shorter amount and duration of additional pain control (p=0.001, p=0.017 each). There was no significant difference in complication after surgery between two groups (p=0.721). All the patients showed pathologic report of benign hemangioma regardless of type of surgery (100%). Almost every patients reported no symptom or relief of symptom in both groups (97.7%, 93.9% each). Conclusions:Laparoscopic liver resection for liver cavernous hemangioma can be safely performed with improved postoperative recovery. However, surgery for liver cavernous hemangioma should be conducted with informed consent of the patients.
