Question 1

i had a neck mri and i the results said "large particularly visualized left maxillary sinus retention cyst". i am having tingling and dull pain in the left side of the head. could this be the cause?

Accepted Answer

See ENT Consult: 29 year old male asks if visualized large left maxillary retention cyst on MRI could cause tingling &amp; dull pain in left side of head. The possibility is there but it is best to see the ENT expert to confirm and treat as appropriate.

Question 2

what is a small retention cyst in the left maxillary sinus?

Accepted Answer

Mucus cyst of sinus: A mucus retention cyst is a common variant seen on ct scans. This is mucus trapped under the mucus membrane lining the sinus. This creates a raised cyst in the sinus typically with no symptoms. Most of the time, no intervention is needed.

Question 3

i'm experiencing nasal congestion and have a retention cyst in left maxillary sinus. what does that mean?

Accepted Answer

Common finding : Usually,  a mucous retention cyst in one maxillary sinus is of little importance or concern. The cyst is  a mucus filled structure on the floor or side walls of the sinus. It can gradually enlarge, but not necessarily. It is unrelated to your nasal congestion. This is something you need to discuss with your otolaryngologist further about long term treatment and follow-up.

Question 4

can a mucous retention cyst in the left maxillary sinus cause headaches, double vision and selling around the eyes?

Accepted Answer

Sinus cyst: Cysts or inflammation of a maxillary sinus can cause cheek discomfort and headaches but double vision would not be usual. An otolaryngologist(ear,nose and throat specialist), opthalmologist or neurologist could advise you further.

Question 5

i recently had a ct scan done on my sinus and i have a 1.6 cm polyp or mucous retention cyst inferiorly in my left maxillary sinus what does it mean?

Accepted Answer

CT finding: The finding of an isolated polyp or retention cyst on a CT scan does not need to be
treated unless you have other symptoms of sinusitis.

Question 6

ct results1mild mucosal thickening involving the ethmoid air cells and small mucous retention in the left maxillary sinus.2small concha bullosa bilaterally without ostiomeatal stenosis. please explain?

Accepted Answer

Sinus CT: Concha bullosa are common anatomic variants of bones in the nasal cavity.  When they are large, they can obstruct the sinus drainage pathway and predispose to sinusitis.  When small, usually of no concern.  Small mucus  retention cysts and mild mucosal thickening may be related to mild chronic sinusitis.  However, these mild findings may not even cause noticeable symptoms.

Question 7

ct scan shows opacification of left maxillary sinus with large soft tissue consistent with polyps/retention cysts. i have terrible daily migraines & want to avoid another surgery. what alternatives?

Accepted Answer

Maxillary sinusitis: Sinusitis doesnt necessarily require surgery. Surgery is required only. When there is recurrent sinusitis with drainage problems.

Question 8

please translate: "mucous retention cyst in right maxillary sinus. bulbous mucosal thickening of left inferior turbinate is noted. mucosal retention cyst is also noted within left aspect of nasopharynx."

Accepted Answer

Retention cysts: Mucus retention cysts in the sinuses are common. As many as 30-40% of asymptomatic patients will have cysts of the sinuses on ct scans. The majority of these shrink without treatment or don’t change over time. Without symptoms or complications, observation is the best course to take. Thickening of turbinates can mean anything, from allergy to anatomic variance.

Question 9

there is semi circumscribed t2 hyperintensity in the right maxillary sinus. retention cyst, right maxillary sinus. please translate?

Accepted Answer

Retention cysts in: The maxillary sinuses are not uncommon and usually do not cause symptoms. They are very thin walled, fluid filled sacs. Unless they obstruct the sinus ostia or are associated with other sinus disease they are usually left untreated. These are often serendipitous findings on head ct's or mri's performed for unrelated reasons.

Question 10

can a polyp or retention cyst in the maxillary sinus cause imbalance?

Accepted Answer

Possible but rare: Polyps or cysts in the maxillary sinuses are very common.  Unless they are obstructing the opening to the sinus, they are completely benign and nothing should be done, especially surgery. If it blocks the opening, a simple endoscopic surgery can remove the blockage and improve symptoms.
