Osteomas of the frontal sinus are usually symptomless. When they enlarge they may produce pressure symptoms such as headaches. Small osteomas developing near the fronto-ethmoidal duct may interfere with the patency of the duct and impair the aeration of the sinus. This is a report of a case in which
We report a case of osteoid osteoma involving the ethmoid sinus, which presented as a unilateral fixed headache with some features suggestive of hemicrania continua.
Frontal sinus osteomas are benign and well-defined masses that may cause various symptoms when they press on the surrounding tissues. Paranasal sinus osteoma is seen as a well-defined mass showing high opacity in Computed tomography. In this case study, we presented here a 53-year-old frontal recess
We reported a case of osteoma involving the frontal recess, which presented as frontal headache and reviewed literatures. Also, this case highlights that sinunasal osteomas can cause pain by local mass effects, referred pain, or prostaglandin E2-mediated mechanisms.
Osteomas are benign, slow-growing tumors originating from bone tissue. Osteomas of the paranasal region, which are usually asymptomatic, are detected incidentally on tomographies taken for other medical needs. Paranasal sinus osteomas frequently localized in the frontal and ethmoid sinuses are among
Osteoma of external auditory canal is a rare benign tumour. Usually it is found incidentally and often symptomless. Here we have a case of osteoma arising from the anterior wall of the bony external auditory canal, causing ipsilateral temporal headache which was relieved by removal of tumour.
Paranasal sinus osteomas are among the rare causes of headache and they are most commonly seen in the frontal and ethmoid sinuses. In this report, we presented the first case of pneumatized nasal septum osteoma causing headache, successfully treated with endoscopic transnasal approach.
Frontal sinus osteoma accompanied by intracranial mucocele and local hyperostosis frontalis interna has never been reported. A 47-year-old woman presented with a 3-month history of intermittent headache. Physical examination revealed no neurologic abnormality. Contrasted magnetic resonance imaging
We present a 43-year-old female patient who had recurrent headache for one year. An intracranial bony lesion surrounded by a cyst in the anterior cranial fossa was found on imaging. Postoperative histological examination confirmed the diagnosis of osteoma and mucocele.
OBJECTIVE
Differential diagnosis is essential, since secondary headache due to paranasal sinus lesions are similar in headache characteristics to primary headache. However, since patients visiting the emergency department due to acute severe headache are primarily treated by neurologists, paranasal
A 35-year-old female suffered sudden onset of severe headache upon blowing her nose. No rhinorrhea or signs of meningeal irritation were noted. Computed tomography (CT) with bone windows clearly delineated a bony mass in the right ethmoid sinus, extending into the orbit and intracranially.
A 39-year old female was referred with a 2 year history of slowly progressive headache, exophthalmos, diplopia and restricted eye movements with exotropia of the right eye. Orthoptic examination revealed restricted elevation and mildly restricted adduction of the right eye. CT and MRI demonstrated a
