A conscious 15-year-old boy presented with progressive proptosis and a severe headache 2 weeks after minor blunt trauma to the head. No neurological deficit was present. Computed tomography demonstrated intracranial and intraorbital cyst-like masses. At craniotomy a subacute extradural haematoma was found which communicated with an orbital subperiosteal haematoma through a shelved orbital roof fracture. The haematomas were drained and the patient made an uneventful postoperative recovery. Although rare, an extradural haemorrhage should be considered in any patient presenting to an ophthalmologist with progressive proptosis and headache following a head injury.

The clinical, neuroradiologic, and pathologic features of an unusual retinal and cerebral giant cell astrocytoma in a 24-year-old man with tuberous sclerosis are reported. The patient was referred at 3 years of age because of partial seizures from the first months of life, severe mental retardation, and left microphthalmos. The microphthalmic eye presented slow growth from 9 years of age and was enucleated at age 18 years because of exophthalmos and pain. At age 23 years, the patient experienced sudden and severe headache. Magnetic resonance imaging revealed a voluminous cystic tumor in the region of the foramen of Monro, lateral ventricle, and basal ganglia of the right cerebral hemisphere. Pathologic examination of the enucleated eye and of the cerebral tumor disclosed the same histologic findings in both locations, a giant cell astrocytoma.

A 55-year-old man reported a severe headache of 3 days' duration, left ptosis and left lid swelling before examination. The ocular examination revealed left eye proptosis, severe edema of the left bulbar conjunctiva and lid, increasing intraocular pressure of the left eye and ptosis on the left side with decreased extraocular movement. The right eye was normal. Hematologic studies indicated mild inflammation. An enhanced computed tomography scan revealed proptosis of the left globe and enlargement of the superior ophthalmic vein and cavernous sinus of the left side. Angiography revealed an area of interrupted blood flow in the left cavernous sinus. Enhanced magnetic resonance imaging (MRI) with Gd-DTPA revealed a low-intensity area that was suspected to be a blood clot in the enlarged left cavernous sinus. This case indicates the efficacy of enhanced MRI examination in the early diagnosis of cavernous sinus thrombosis.

A woman developed headaches, transient visual obscurations, anosmia, and decreased visual acuity. Ocular examination showed bilateral pulsatile proptosis and disc edema with choroidal folds. Standardized ophthalmic echography showed absence of bony orbital roofs, prominent dural pulsations, direct apposition of brain parenchyma and orbital tissues, and echographic signs suggesting bilateral optic nerve compression. CT and MRI showed a large defect in the floor of the anterior cranial fossa. The cribriform plate, both orbital roofs, and sphenoid bones were displaced by a large basal encephalocele. Clinical improvement followed reconstruction of the anterior cranial fossa and decompression of both optic nerves.

Acute, noninfectious orbital inflammations often defy a specific diagnosis despite a thorough medical evaluation and are grouped in the nonspecific diagnostic category of idiopathic inflammation of the orbit (pseudotumor). An atypical case of cluster headache presenting with intermittent migratory facial swelling and orbital inflammation, and 3 mm of exophthalmos simulating idiopathic orbital inflammation is presented. Although periobital pain is a frequent finding in patients suffering from cluster headaches, to the authors' knowledge this is the first reported case of orbital inflammation with cluster headache. After unsuccessful treatment directed at potential infectious and inflammatory causes, the patient responded well to methysergide, an established treatment for cluster headaches. A review of the known mechanism for this disorder, peripheral and central nervous system mechanisms of pain, and migratory angioedema reveals overlapping pathophysiology, clinical findings, and associated symptoms.

We report a case of intraorbital conjunctival cyst following a penetrating orbitocranial injury. The patient was a 28-year-old male who was hospitalized with exophthalmos, retrobulbar pain and upper gaze disturbance of his left eye. When he was 4 years old, a thin iron rod had penetrated intracranially through the inner angle of his left orbit. He was hospitalized and treated conservatively for about two weeks. The left eye ball was intact and visual acuity was normal, although bloody fluid had continuously flowed out from the left inner angle of the conjunctival wound for a few days. He had been febrile to 39 degrees C and complained of headache for one week. Subsequentry, the symptoms gradually improved through conservative therapy. When he was a junior high school student, he noticed exophthalmos of his left eye. However, he had never been examined closely, until he was 28 years old. We suspect that he had suffered from meningitis caused by the penetrating orbitocranial injury, and had fortunately improved under the conservative therapy. On admission to our hospital, a craniogram showed fracture of the left orbital roof, and coronal and three-dimensional computed tomography (CT) scans clearly demonstrated the orbital fracture. CT revealed a cystic mass in the retrobulbar space, and a porencephalic cyst in the medial basal frontal lobe. On magnetic resonance imaging (MRI) scans, both cysts were of low intensity on T1-weighted imaging, and of high intensity on T2-weighted images. Coronal and sagittal MRI scans showed that the two cysts were connected with each other through the fracture in the orbital roof. We diagnosed therefore that the orbital cyst was a herniated porencephalic cyst of the frontal lobe. Surgery was performed by a transcranial approach. The porencephalic cyst adhered to the fractured lesion of the frontal base but did not extend into the orbita. The intraorbital cyst was totally removed by opening the orbital roof including the fractured lesion. The cyst contained milky fluid. Postoperatively, the exophthalmos, retrobulbar pain and upper gaze disturbance showed gradual improvement. On histological examination, the cyst was found to be lined by non-keratinized stratified squamous epithelium and was diagnosed as a conjunctival cyst. This case was considered to be one of traumatic conjunctival cysts caused by a penetrating orbitocranial injury. Orbital conjunctival cysts have been reported to comprise about 10% of orbital epidermoid and dermoid cysts. Of these cysts, traumatic conjunctival cysts are rare, and only a few cases have been described. The etiology and therapy of orbital conjunctival cysts are discussed.

A case of eosinophilic granuloma of the lesser wing of the sphenoid bone is reported. The patient was a 5-year-old white male, with left temporal-frontal headache, left III cranial nerve palsy, left exophthalmos and ptosis caused by an osteolytic lesion of the anterior clinoid process extending to the left optic canal and cavernous sinus. The patient underwent surgical resection of pathologic tissue. Pathologic diagnosis was eosinophilic granuloma of the sphenoid bone. Surgical management, postoperative prognosis and differential diagnosis of eosinophilic granuloma of the skull base are discussed along with a review of the literature.

A 31-year-old woman complained of sudden diplopia and proptosis associated with a headache. Approximately 10 years earlier, she had sustained a right orbital blowout fracture during a snow machine accident that was repaired using a Supramid implant. She presented with 4 mm of right-sided proptosis by Hertel exophthalmometry, with limitation of up and down gaze. She manifested a right gaze preference with a left head turn to achieve fusion. Visual acuity was 20/20 on both sides; however, there was 20% red desaturation and a subtle afferent pupillary defect on the right side. Goldmann visual fields were full and the retinal examination was normal. A computed tomography (CT) scan of the orbits with and without contrast demonstrated a large right posterior inferior orbital mass. Once the periorbita was breached during orbitotomy, a burgundy serosanguinous material emerged. Gram staining revealed red cells without organisms. The implant had not been fixed by wires or screws. Upon removal, the implant appeared oversized, encompassing the orbital floor, medial and lateral walls. Postoperatively, the proptosis, gaze preference with face turn, afferent pupillary defect, desaturation abnormality, and diplopia resolved.

Three unusual cases of sphenoethmoidal mucoceles with rare intracranial extension are reported. A 64-year-old female presented with a 7-month history of right visual disturbance. Computed tomography (CT) and magnetic resonance (MR) imaging demonstrated a huge mass in the right middle fossa. She underwent right frontotemporal craniotomy. Postoperatively, her proptosis and cranial nerve dysfunction had improved markedly. A 53-year-old female complained of headache, nausea, and dizziness. CT and MR imaging revealed a cystic mass filling the right sphenoid sinus. The cystic lesion was evacuated through the transnasal approach. She was doing well postoperatively and has been asymptomatic. A 39-year-old male complained of headache, vomiting, and right visual disturbance. CT and MR imaging demonstrated a homogeneous mass occupying the sphenoid sinus. Sphenoidotomy exposed the cyst extending superiorly into the anterior cranial fossa. He recovered from the visual disturbances and has been asymptomatic since. MR imaging provides confirmation of the diagnosis of sphenoethmoidal mucocele and is important for preoperative evaluation.

Subperiosteal hematoma of the orbit is a rare but well-recognized entity, usually caused by trauma. Two cases of subperiosteal hematoma associated with sinusitis are presented. A 44-year-old woman experienced the sudden onset of proptosis, and decreased visual acuity. Computed tomographic scanning and magnetic resonance imaging revealed a frontoethmoidal mucocele and a biconvex mass in the upper part of the left orbit. The mucocele was drained during nasal endoscopic surgery and the subperiosteal hematoma was evacuated during superior orbitotomy. A 42-year-old man had a headache and proptosis. Computed tomographic scan revealed sinusitis and subperiosteal orbital hematoma of the left orbit. Subperiosteal orbital hematoma associated with sinusitis is extremely rare but should be suspected in a patient with acute onset of proptosis in whom computed tomographic scanning reveals paranasal sinusitis.
