Project description:Benign cardiac hemangiomas are rare tumors that may present in or out side of the heart, epicardium being the most common site. Echocardiography is the method of choice in diagnosing cardiac masses and though 3D TEE may seem to add exact information about the location, the time constraint in doing a comprehensive examination along with 3D rendering inside operation room may become an hindrance.

Project description:BackgroundCavernous hemangiomas, more accurately defined as cavernous venous malformations, constitute the most common primary intraorbital tumors of adults comprising 4-9% of all tumors,[4] and the second most frequent cause of unilateral proptosis after thyroid-related orbitopathy.[3] Over 80% are located within the intraconal compartment, most commonly in the lateral aspect.[1] Surgical treatment for orbital cavernous hemangioma is generally required in symptomatic cases, optic nerve compression, and cosmetically disfiguring proptosis.[2] Transcranial approaches, the most familiar approaches for neurosurgeons, provide wide access to the entire superior and lateral orbit. They usually offer direct visualization, allowing for a safer dissection, while minimizing significant injury to the native neural and vascular anatomy of the orbit.[5] Although transcranial approaches continue to evolve, in many cases, they have been supplanted by endoscopic skull base approaches and modifications to deep lateral orbitotomy approaches.[5].Case descriptionA 62-year-old male patient presented with slowly expanding left proptosis, which he had first noticed 3 years before presentation. He was already blind in his right eye due to a history of traumatic amaurosis in childhood. The left eye examination revealed severe proptosis with restricted eye movement in all directions and significant visual impairment (visual acuity of 20/300, expressed by Snellen test, with no improvement on correction). MRI of the orbit showed a large left superolateral intraconal cavernous hemangioma compressing and displacing the optic nerve, with the typical feature of slow gradual irregular enhancement with delayed washout on contrast-enhanced image. A one-piece modified orbitozygomatic approach was performed and a total en block resection was achieved. The bone flap was fixed with titanium miniplates and screws, the temporal muscle and the skin were closed in a standard fashion. The patient did not present any new deficit in the postoperative period. The patient had good functional and cosmetic outcomes with resolution of proptosis, restoration of eye movements, and improvement of visual acuity in the 3-month follow-up. Postoperative MRI showed total resection.ConclusionThe orbitozygomatic approach for large orbital cavernous hemangioma provides satisfactory orbital decompression and large working space, reduces traction, and increases visualization and freedom to dissect small vessels and nerves that may be tightly attached to the tumor pseudocapsule.

Project description:Lower gastrointestinal (GI) bleed due to hemangioma in rectum is an uncommon problem. A 19-year-old female patient presented with history of recurrent episodes of lower GI bleeding 1-2 times/month for last 3 years. At the time of hospitalization her vital signs were normal and rectal examination revealed frank blood. Investigations revealed a hemoglobin level of 8.9 g/dL and normal coagulation parameters. Colonoscopy showed bluish reddish elevated nodular lesions limited to distal rectum. Magnetic resonance imaging and endoscopic ultrasound showed cavernous hemangioma.

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:BackgroundAdrenal hemangioma is a rare benign adrenal tumor that is usually misdiagnosed preoperatively. We here present a case of adrenal cavernous hemangioma that was successfully treated with retroperitoneal laparoscopic adrenalectomy.Case presentationA 67-year-old man with dull right back pain attended our clinic for examination of a mass on the right adrenal gland for 1 week. Pheochromocytoma was considered according to the preoperative computed tomography angiography + computed tomography urography findings and was subsequently corrected to adrenal gland hemangioma according to postoperative pathological findings. The patient showed no recurrence of adrenal hemangioma during the 1-year follow-up period after surgery.ConclusionAdrenal gland hemangioma is rare with a high rate of misdiagnosis, and it should be considered in imaging findings of adrenal tumors with typical hemangioma. Surgery is an effective treatment method.

Project description:BackgroundCavernous hemangioma are the most common benign lesions of the orbit. Their surgical resection is still challenging and several surgical approaches have been proposed.Case descriptionWe 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.ConclusionThe 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: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:BackgroundPatients with upper limb pain often have a slumped sitting position and poor shoulder posture. Pain could be due to poor posture causing mechanical changes (stretch; local pressure) that in turn affect the function of major limb nerves (e.g. median nerve). This study examines (1) whether the individual components of slumped sitting (forward head position, trunk flexion and shoulder protraction) cause median nerve stretch and (2) whether shoulder protraction restricts normal nerve movements.MethodsLongitudinal nerve movement was measured using frame-by-frame cross-correlation analysis from high frequency ultrasound images during individual components of slumped sitting. The effects of protraction on nerve movement through the shoulder region were investigated by examining nerve movement in the arm in response to contralateral neck side flexion.ResultsNeither moving the head forward or trunk flexion caused significant movement of the median nerve. In contrast, 4.3 mm of movement, adding 0.7% strain, occurred in the forearm during shoulder protraction. A delay in movement at the start of protraction and straightening of the nerve trunk provided evidence of unloading with the shoulder flexed and elbow extended and the scapulothoracic joint in neutral. There was a 60% reduction in nerve movement in the arm during contralateral neck side flexion when the shoulder was protracted compared to scapulothoracic neutral.ConclusionSlumped sitting is unlikely to increase nerve strain sufficient to cause changes to nerve function. However, shoulder protraction may place the median nerve at risk of injury, since nerve movement is reduced through the shoulder region when the shoulder is protracted and other joints are moved. Both altered nerve dynamics in response to moving other joints and local changes to blood supply may adversely affect nerve function and increase the risk of developing upper quadrant pain.
