An 8-year-old boy suffered severe craniocerebral trauma with left-sided fronto-orbitobasal fracture. The CT scan showed minor subdural air inclusions. The child recovered well and had no clinical signs of aftereffects. Eight years after the accident, symptoms of intracranial pressure developed progressively with nuchal rigidity and elevated temperature. The CT showed an extensive left fronto-orbitobasal abscess. The intraoperative finding was a brain prolapse both into the frontal sinus and into the ethmoidal cavity with a large dura-bone defect at the site of the former fracture line, which was closed with refobacin-bone-meal fibrin sealant plasty and glued periostal patch. The postoperative course was unremarkable. Evidently, the accident had caused a brain prolapse into the bone defect, which prevented liquorrhea. Due to the lack of bone and dura barrier, a late brain abscess developed in the course of sinusitis. In such cases, primary surgical revision seems to be indicated.

Orbital-cranial injuries have the greatest potential for death and disability of any condition treated by the ophthalmologist. An object that penetrates through the orbit into the brain may leave only a small entrance wound. Patients can have normal vision, neurologic exam, and plain x-rays despite trauma that may lead to meningitis, brain abscess, or pneumocephalus. The CT scan greatly aids in both the early and late management of blunt and penetrating orbital-cranial trauma. The detection of pneumocephalus may be the only clue that intracranial penetration has occurred. Blunt trauma can cause vision loss, ophthalmoplegia, ptosis, and intracranial injury. Management of orbital-cranial trauma frequently requires a team approach by the ophthalmologist and neurosurgeon due to the complexity of these injuries.

We report the case of a 73-year-old female who presented facial numbness and pain in the first division of the trigeminal nerve, ptosis, diplopia and visual loss on the right side for the previous four months. The neurological, radiological and histological examination demonstrated a rare case of invasive fungal aspergillosis of the central nervous system, causing orbital apex syndrome, later transformed in temporal brain abscess. She died ten months later due to respiratory and renal failure in spite of specific antimycotic therapy.

We report a case of unilateral mydriasis associated with sphenoid sinusitis and mucocele in a child. An 11-year-old girl with a history of unilateral mydriasis was referred for ophthalmologic examination. She complained of a mild headache over the past four days. The right pupil was dilated and nonreactive to light. The left pupil was normal and reactive. There was no ptosis or other focal neurological deficit. She was orthotropic. Visual acuity in both eyes, ocular motility and fundi were normal. Magnetic resonance imaging (MRI) showed a sphenoid sinus mucocele with sphenoiditis. The diagnosis was partial third nerve palsy without ophthalmoplegia. Treatment with antibiotics was initiated and led to complete resolution of the mydriasis. Sphenoid sinus mucoceles are relatively rare. Failure to diagnose and treat can lead to serious neurologic sequellae such as third nerve palsy, compressive optic neuropathy, cavernous sinus thrombosis, meningitis or brain abscess. Head imaging by reconstructed CT and MRI can lead to the diagnosis of mucocele. Isolated unilateral mydriasis as a sign of third nerve palsy may be caused by a slowly enlarging lesion. In a child with isolated unilateral mydriasis, head MRI should be performed to rule out a compressive lesion of the oculomotor nerve.

Mucoceles are benign mucus-containing cysts formed due to the obliteration of sinus ostium. They are most commonly found in the frontal sinus. Mucoceles can spread both intraorbitally and intracranially causing complications such as meningitis, brain abscess, and loss of vision. Radiological investigations are required for diagnosis, with both computed tomography (CT) and magnetic resonance imaging (MRI) being useful. Surgical approaches for management have changed from external to endonasal these days. We report a case where a 54-year-old patient presented to us with a 14 days' history of loss of vision and complete closure of eyes over 2 days. Contrast-enhanced CT scan and MRI confirmed the diagnosis of frontoethmoidal mucocele breaching the left frontal sinus floor. Endoscopic orbital decompression with functional endoscopic sinus surgery was done. Eye movements and ptosis recovered completely after the surgery, but the vision did not. Although the etiology of mucocele is multifactorial, obstruction of sinus ostium is the most plausible cause. Increasing pressure on adjacent structures by the expanding mucocele can cause intraorbital and intracranial complications. MRI is superior to CT in differentiating mucocele from soft-tissue neoplasms, although CT gives a more detailed information on bone structure. Endoscopic approaches have become the most preferred way to access frontoethmoidal mucoceles, with external approaches being reserved for mucoceles in certain inaccessible locations. Timely intervention is imperative to prevent undesirable complications.
