Facial lacerations are a common presentation in emergency departments. It is important to appreciate the mechanism of injury and the anatomy of structures involved in penetrating lacerations in the maxillofacial region. A 65-year-old man suffered an accidental penetrating injury with a sharp kitchen knife to the right temporal region. There was a single laceration to the right temporal region. The right eye had no perception to light, a total afferent and efferent pupillary defect and partial ophthalmoplegia. Computerised tomography scan revealed signs of penetration through the skin, temporalis, postero-lateral orbital wall and orbital apex. There was no injury to the globe or either retrobulbar or intracranial haemorrhage. A diagnosis of direct traumatic optic neuropathy was made following consultation with opthalmology and neurosurgery teams. Only two similar cases of penetrating trauma in the temporal region resulting in direct traumatic optic neuropathy have been identified in the literature. This case presentation highlights the structures that are at risk of damage from penetrating trauma in the maxillofacial region.

Abstract Purpose To present a case of activation of Leber hereditary optic neuropathy (LHON) following head and ocular trauma of the fellow eye in the patient with no remarkable symptoms and normal visual acuity prior to trauma. Case summary A 31-year-old healthy man was referred to our hospital after a traffic accident. He had blowout fractures of medial and inferior orbital wall of the left eye, subcutaneous hematoma of the left forehead, and bony fragment that compressed the left optic nerve. Initially, best-corrected visual acuity (BCVA) was 20/20 in the right and 20/1000 in the left eyes. Relative afferent pupillary defect of the left eye was apparent, and fundus examination revealed choroidal rupture circumferentially crossing the macular area. Nine months later, the patient complained with gradual vision loss in the right eye, which was the contralateral eye of the ocular trauma. BCVA was 20/200, and perimetry revealed cecocentral scotoma in the right eye. BCVA in both eyes reduced to 20/2000 1 year post-trauma. Visual evoked potentials revealed markedly decreased in amplitudes and elongated latencies for both eyes. Mitochondrial DNA analysis revealed a G11778A mutation; therefore, a diagnosis of activation of LHON followed by trauma was made for the previously unaffected carrier. Conclusions This is a case in which activation of LHON occurred in a healthy carrier following head and ocular trauma of the fellow eye. This observation suggests the possibility that LHON activation in healthy carriers may occur in patients who experience head or ocular trauma even in the fellow eye.

Partial Status

Complex partial status epilepticus (SE) has been reported rarely in children. We describe the clinical case of a 14 year-old girl with complex partial seizures (CPS) since age 10 who developed a complex partial SE probably because she was not adherent to treatment. The neurologic examination and computed tomography scan were normal. During the SE she received diazepam and phenytoin and became free of the seizures after 5 minutes. The ictal EEG showed spikes and slow waves over the right temporal region.

Abstract Background Thoracic surgeons rarely encounter stab wounds with injury to the intrathoracic organs. However, such sudden and urgent situations could arise; therefore, experiences in managing such cases are invaluable. Case presentation An 84-year-old woman with depression who had a stab injury in the neck caused by a broad-bladed kitchen knife was brought to our facility by ambulance. She was stable in the emergency room; however, a computed tomography scan revealed that the blade had penetrated the right thoracic cavity. A right hemopneumothorax was seen. Considering the possibility of injury to the major vessels, a median sternotomy was performed. During the dissection around the blade, the patient started bleeding profusely, which required repair of an injury to the right internal jugular vein. The blade tip had penetrated the dorsal right upper lung lobe; however, it did not reach the hilum, and the knife was carefully removed. The damaged area of the lung was removed by wedge resection. Conclusion Patients with deep stab wounds from knives are often hemodynamically stable because the blade acts as tamponade and prevents hemorrhage. Therefore, a surgical approach that allows for good visualization should be considered for the extraction of the blade.

Introduction. Retinal vein occlusion is the largest group of retinal blood vessel abnormalities after diabetic retinopathy. Macular edema and neovascularization are major complications in BRVO that require therapy. Vitrectomy is indicated in cases of vitreous hemorrhage that fail spontaneous resolution after 6 weeks to 3 months. The time to do vitrectomy depends on the tendency of the ophtalmologist and the patient's visual needs. Case Presentation. A woman, 59 years old, housewife, came to the Eye Clinic on July 2016. The main complaint history is that the right eye has become more blurred since ± 2 months ago. On examination of the posterior segment of the right eye the detail is difficult to assess. In this patient suspected turbidity of the vitreous cavity so that an ultrasound examination was performed. Vitreous bleeding is an indication for vitrectomy. Intraoperatively after the vitrectomy, bleeding and ghost vessels were found in the super-temporal region. Conclusion. The main goals of therapy in BRVO are to improve hemodynamics, overcome macular edema, and prevent neovascularization.

Tomography Scan

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

Purpose: To report a case of right eye blindness due to a penetrating injury in the contralateral nostril. Methods: This is a case report of a 67-year-old patient who presented to the emergency room complaining of transient blurred vision in his right eye after falling on a small branch with no apparent injury besides minor lacerations. The following day, the patient experienced blindness in the right eye. Physical examination revealed small lacerations on his left forehead and optic neuropathy on the right side with no other obvious discerning physical or imaging abnormalities. Results: After elevated suspicion and reassessment of the neuroimaging findings, a radiolucent track was observed in the nasal cavity, continuing up from the left nostril to the right optic nerve. Transnasal endoscopic surgery was performed and a long wooden branch was removed from the nasal cavity. Conclusion: A nasally penetrating wooden foreign body can cause traumatic optic neuropathy and vision loss on the unaffected side and can be very difficult to locate and image without any clear external evidence as to its presence. This case highlights the importance of maintaining a high level of suspicion in these types of cases.

Traumatic optic neuropathy is sinister sequelae of craniofacial trauma leading to vision loss. The decision between early medical or surgical intervention is usually individualised. Visual evoked potentials may guide the treatment plan. We describe a young male presenting 5 days after a road traffic accident with no perception of light vision in the right eye. He was managed medically with high dose of intravenous steroids. At the 3-month follow-up, he reported a reversal of vision loss with return of visual acuity to 3/60, which improved to 6/36 at 5 months and remained stable at 8 months.

Abstract Background The classic Lemierre’s syndrome refers to a septic thrombosis of the internal jugular vein, usually caused by a Fusobacterium necrophorum infection starting in the oral cavity, and typically complicated by pulmonary emboli. However, unusual forms of the disorder have been rarely reported. Case presentation We describe an unusual case of a previously healthy 58-year-old male with Lemierre’s syndrome, manifesting with lumbar pain and fever. A thrombosis of the iliac veins and abscesses in the right iliac and the left psoas muscles was diagnosed by a computed tomography scan, together with a right lung pneumonia complicated by pleural effusion and an L4-L5 spondylodiscitis. Blood culture and pus drainage were positive for Fusobacterium nucleatum and an atypical Lemierre’s syndrome was suspected. The patient was treated with anticoagulant therapy for 12 weeks and intravenous antibiotic therapy for 6 weeks with a good evolution and resolution of the thrombosis. Conclusions This case illustrates the thrombogenic and thromboembolic tendency of Fusobacterium nucleatum and its potential invasiveness, regardless of the site of primary infection. The concept of an atypical Lemierre’s syndrome is redefined here to take into consideration non-cervical sites.
