“…The presenting symptoms are usually a painful swelling of several months’ duration, focal neurologic deficits, proptosis and hearing loss [4,5,6]. Destruction of the posterior ear canal and fallopian canal with subsequent facial nerve exposure has been reported [7].…”

Aneurysmal bone cyst (ABC) of the skull is exceedingly rare. We report a unique case of an intradural ABC without bone involvement presenting with raised intracranial pressure. The patient was a 14-year-old boy who presented with headache, vomiting and right focal seizure. Imaging showed a large multicystic left frontal lesion without any evidence of bone involvement. The lesion adherent to an intact sphenoid wing dura was completely excised. The histopathology report was consistent with an ABC. This case represents the first report of an ABC without involvement of the skull bones or any evidence of dural erosion. The possible mechanism of origin at this unusual location is hypothesized.

Objective/Hypothesis Aneurysmal bone cysts (ABCs) are benign, lytic bone lesions, which rarely present in the paranasal sinuses. There is no published consensus on the appropriate diagnostic or treatment approach. Our objective was to elucidate the clinical behavior, treatment, and outcomes for patients with ABCs of the paranasal sinuses (psABCs). Study Design Retrospective case series and system review of the literature. Methods A retrospective chart review was performed to identify patients evaluated at the authors' institution with psABC and consolidated with literature reports of psABC. Results Eighty‐nine patients met inclusion criteria. The most common presenting symptom was painless facial swelling (n = 35, 39%). The ethmoid sinuses were the most common site involved (n = 55, 62%). Surgical approach was reported in 74 cases including 20 endoscopic and 54 with an open or combined approach. Fifty‐nine patients (71%) underwent gross total resection. Follow up data was reported for 67 patients. Fifteen patients (22%) were found to have recurrence or progression at follow up; 10/15 (66%) patients within the first 12 months, 14/15 (93%) within the first 24 months, and 1/15 (7%) greater than 24 months after treatment. Patients were more likely to have recurrence/progression if they presented with nasal discharge (P = .05), proptosis (P = .01), or orbital involvement (P = .03). Conclusions psABCs typically present with painless swelling or nasal obstruction. Orbital involvement is a negative prognostic indicator with these patients more likely to have recurrence after treatment. Recurrence or progression of disease is most likely to occur within 2 years after treatment. Therefore, patients should be monitored closely during this time.

We present an unusual case of an epidermoid cyst in the sphenoid sinus with extensive bony erosions and mass effect, compressing the optic nerve causing visual disturbances. Epidermoid cysts of the paranasal sinuses are extremely rare cases. They usually present as intradural, extraaxial, benign masses of the cerebellopontine angle but they should also be considered in the differential diagnosis of sphenoid sinus lesions. The typical imaging appearance of craniocerebral epidermoid cysts is demonstrated and pathophysiological considerations of formation in the paranasal sinuses are discussed. ZusammenfassungWir präsentieren einen Fall mit der ungewöhnlichen Lokalisation einer Epidermoidzyste im Sinus sphenoidalis mit ausgedehnten knöchernen Arosionen, Zeichen der Raumforderung und Kompression des Nervus opticus. Die Nasennebenhöhlen sind ein äußerst seltener Manifestationsort der Epidermoidzysten. Gewöhnlich zeigen sie sich als intradural und extraaxial gelegene benigne Raumforderungen des Kleinhirnbrückenwinkels. Sie sollten jedoch in die Differentialdiagnose der Läsi-onen des Sinus sphenoidalis eingeschlossen werden. Die charakteristische Bildgebung kraniozerebraler Epidermoidzysten wird demonstriert, und pathophysiologische Erklärungen zur Entstehung in den Nasennebenhöhlen werden diskutiert.
