A rare type of tumor: orbital schwannoma. Case report and literature review

Abstract Schwannomas arise in the cells responsible for the mielinating the neurons distal to the Obersteiner-Redlich zone. Most of the intracranian Schwannomas are in the posterior fossa, developed from the VIIIth or Vth nerve stheath. The location on other cranian nerves is quite rare, only 6% of the orbital tumors being Schwannomas. We review the case of a 52 years old male patient, presenting for right eye exophthalmia and visual field deficit, diplopia due to VIth nerve paresis, and stubbing pain in the right eye, the MRI showing a tumor, located in the orbital apex displaced the globe forward and superiorly, and the optic nerve medially and superiorly. A modified lateral orbital approach was preferred. The choice of the orbitotomy allowed us to maintain the integrity of the lateral rim of the orbit without the need of a bony reconstruction at the end of the intervention, as it faced the anterior margin of the temporal muscle, covering it and not the skin over the zigomatic bone. The technical approach for orbital schwanomas should be tailored to reach the lesion through an esthetic incision and orbitotomy, immediately under the resected bone, with no need retracting the ocular globe or the vasculonervous elements in the orbit.

Introduction. Heart injuries can be classified as penetrating and non-penetrating (blunt). Penetrating wounds are usually caused by stabbing with a piercing object, weapon or projectiles - missiles. The right atrium is damaged in most cases, because of its anatomical position - making the most of the anterior side of the heart. Morbidity caused by stabbing injuries to the heart is 20%-30%, while piercing wounds cause 30%-60% of deaths. Case report. A 28-year-old patient was admitted to our clinic with acute ischemia of the extremities. Angiography revealed a bullet in the right common femoral artery, occluding it. The patient denied having any piercing or shooting wound to his leg, but he said that four years before he had been shot to his chest. Echocardiography revealed an atrial septal defect of secondary type. An event reconstruction revealed that, four years after shooting, the bullet was displaced from the heart to the right common femoral artery. Conclusion. This case report is unique because of the rare type of injury, time that passed from the injury, the way bullet entered the artery (via atrial septal defect) and especially the success of both surgical procedures (embolectomy and repair of atrial septal defect).

Purpose To present a case with co-existence of Cogan-Reese syndrome and exfoliation syndrome. Case report A 72-year-old Caucasian woman presented for consultation due to uncontrolled intraocular pressure (IOP) of the right eye. Clinical examination revealed the presence of Cogan-Reese syndrome and exfoliation syndrome OD. This eye exhibited elevated IOP, open anterior chamber angle, advanced glaucomatous optic nerve head damage, and severe glaucomatous visual field loss. The left eye was completely normal without IOP elevation or visual field damage. To our knowledge this is the first case report demonstrating the coexistence of the Cogan-Reese syndrome, exfoliation syndrome, and secondary open-angle glaucoma. Since both syndromes frequently lead to secondary open-angle glaucoma, it is not feasible to determine with certainty which condition was the cause of secondary open-angle glaucoma in our case. It is conceivable that both conditions contributed to glaucoma development. Conclusions Cogan-Reese syndrome, exfoliation syndrome and secondary open-angle glaucoma may present on the same eye.

Case report of a long term diabetic patient with partial motor crises originating from passive movement of the right arm. This is a rare type of crisis when compared to spontaneous partial crisis in diabetic patients. Partial crises are often the initial manifestation of diabetes mellitus (about 19% of the cases reported). As in those cases registered in the literature, crisis control in this case was obtained by normalization of glycose serum levels. Possible mechanisms involved in the pathogenesis are discussed.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.
