There is an increasing use of "Novel Psychoactive Substances" containing synthetic cannabinoids worldwide. Synthetic cannabinoids (SC) are highly addictive and cause severe adverse effects. The purpose of our study was to assess whether chronic use of SC alters brain volume and function. Fifteen SC chronic users and 15 healthy control participants undertook an MRI scan to assess brain volume and function while performing a working memory N-back task and a response-inhibition Go-No-Go task. SC users showed impaired performance on the N-back task but not on the Go-No-Go task...

Isolated traumatic oculomotor nerve (ON) palsy is an uncommon clinical presentation of mild traumatic brain injury (TBI). There are very few cases in which it has been possible to demonstrate the isolated damage of the ON by avulsion of the roots, accompanied with traumatic axonal injury and intraneural microhemorrhage. We present a 23-year-old female who, after mild TBI, began to experience right ptosis, binocular diplopia, and photophobia. Clinical examination showed a complete ophthalmoparesis of the right ON, without other neurological deficits...

Trapdoor fractures are common in children because of elastic nature of the pediatric bone. Clinical signs and radiological evidence in these cases may be minimal.This study involves a 14-year-old girl who sustained blunt trauma to her left eye. Initial investigation, for pure orbital floor fracture included computerized tomography (CT scan) of the orbit, did not show any evidence of incarcerated rectus muscle. She had no limitation of extraocular movements nor enophthalmos. Following conservative treatment, she had a left persistent orbital pain and left monocular diplopia...

REVIEW
Christopher Lo, Shoaib Ugradar, Daniel Rootman
Orbital imaging plays a central role in the diagnosis and management of thyroid-related orbitopathy (TRO). Diagnostically, it is used to compliment a careful ophthalmic examination, laboratory values, and ancillary studies to confirm the presence of TRO and/or dysthyroid optic neuropathy (DON). It can also be helpful in surgical planning and understanding the progression of thyroid myopathy. Computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine all have applications in the field...

Invasive fungal sinusitis causes painful orbital apex syndrome with ophthalmoplegia and visual loss; the mechanism is unclear. We report an immunocompromised patient with invasive fungal sinusitis in whom the visual loss was due to posterior ischaemic optic neuropathy, shown on diffusion-weighted MRI, presumably from fungal invasion of small meningeal-based arteries at the orbital apex. After intensive antifungal drugs, orbital exenteration and immune reconstitution, the patient survived, but we were uncertain if the exenteration helped...

Background: Giant cell tumor of bone originating from the connective tissue within the bone marrow is benign but locally aggressive lesion. In all, 90% of the cases involve the epiphysis of long bones and less than 2% involve the skull. Giant cell tumors of the skull occur most frequently in the sphenoid and temporal bones, and very rarely in the ethmoid, frontal, parietal, and occipital bones. We would like to share a case of giant cell tumor of bone arising from the left orbital roof with involving ethmoid sinus, which was diagnosed to be a meningioma before surgery...

Adenoid cystic carcinoma (ACC) is a rare malignant secretory gland tumor. It is characterized by slow growth, long clinical course, local recurrences, and distant metastases. In the sinonasal tract, it most commonly arises in the maxillary sinus. It often presents at an advanced stage with perineural spread (PNS). Our patient presented with left-sided facial numbness without other symptoms. The numbness was localized to the left cheek, left side of nose, and left upper lip. Magnetic resonance imaging (MRI) of the brain revealed an enhancing lesion involving the left maxillary sinus with orbital invasion and posterior extension into the cavernous sinus...
