Osteomas are slow growing fibro-osseous lesions. Very rare to occur in paranasal sinuses. Small osteomas don't require any intervention. Giant osteomas may require surgical intervention due to its cosmetic and functional compromises. A 28 year old male presented with swelling over forehead and left orbit for more than 4 years. The swelling is around 6 × 5 cm with gross lateral and inferior deviation of left eyeball. Extradural fronto-ethmoidectomy was done with combined external and endoscopic approach. There was pearly white bony hard, fixed tumor mass seen infiltrating anterior and posterior table of frontal bone. All the tumors removed in piecemeals. Wait and watch policy is the usual treatment policy for small and asymptomatic osteomas. Combine external and endoscopic approach is the treatment of choice for giant frontoethmoid osteoma.

PURPOSE
To report a very rare and atypical case of an elderly Caucasian female patient who developed perilesional multiple polypoidal choroidal vasculopathy (PCV) as a probable complication of choroidal osteoma (CO), associated to preretinal neovascular membrane overlying the lesion.
METHODS
Observational case report.
CASE OBSERVATION
A 60-year-old Caucasian woman presented with blurred vision in her right eye (RE). Fundus examination revealed a round white-yellowish calcified deep lesion in the juxta-papillary superior area, measuring 4 disc-diameters, with well-defined scalloped margins and an irregular surface. B-scan ultrasonography and orbital tomography confirmed the diagnosis of choroidal osteoma (CO). Further investigation with multimodal imaging including infracyanine green angiography, fluorescein angiography, swept source optical coherence tomography and angiography highlighted the presence of multiple aneurysmal choroidal dilations around the CO, corresponding to PCV. We also noted the presence of a preretinal neovascular membrane overlying the CO. The patient was monitored with regular follow-up since no signs of activity were detected on multimodal imaging.
CONCLUSION
Our case report represents an exceptional and atypical association between pre-retinal neovascularization, PCV and choroidal osteoma. While the mechanisms underlying the development of PCV and pre-retinal neovascularization in the setting of CO are not well understood, it is imperative for ophthalmologists to recognize this association as a potential cause of sudden vision loss in patients with CO, and to consider appropriate diagnostic and management strategies.

Heterotopic ossification is a rare but debilitating situation. It occurs in patients who have undergone paralysis and/or immobilization. Hip osteoma is one of the most frequent locations and is associated with a significant functional handicap. Its treatment is based on surgical resection, which is a risky surgery that is not devoid of complications such as infections, hematoma, and recurrence. We describe in this paper a new surgical technique that adds to the classic hip osteoma resection: guidance with a navigation system coupled to a 3D imaging tool. We performed this technique on two patients (three hips, one bilateral case). We think that this technique makes the surgery safer with fewer complications.

In the elbow joint, occurrences of intra-articular osteoid osteoma are uncommon. We detail the case of a 21-year-old male who experienced pain, inflammation, and a restricted ability to move his elbow. For a few months, the diagnoses was missed and the patient was treated for idiopathic synovitis. After a contrast MRI, the tumor was revealed. During an arthroscopic examination of the elbow, a distinct red lesion was observed after the removal of the pale reactive bone in the olecranon cavity. This was subsequently removed in its entirety with the aid of a specialized bone tool. Histopathology confirmed the diagnosis of osteoid osteoma. Remarkably, the individual reported alleviation from the symptoms just a day following the operation and regained full range of motion 5 weeks after the surgery. This case underscores the efficacy of arthroscopy in addressing intra-articular osteoid osteoma, with a focus on accurately pinpointing the lesion.

Rhinolithiasis is a rare clinical presentation and may be a diagnostic challenge, often mimicking other intranasal pathologies and difficult to differentiate based on imaging alone. We present the case of a 50-year-old patient with rhinolithiasis who presented with chronic left nasal obstruction and unilateral cyclic pain with foul discharge. After review of her imaging, she was initially misdiagnosed with an intranasal osteoma via telehealth and scheduled for surgical resection. Her true pathology of rhinolithiasis was subsequently identified and treated during an in-person pre-operative clinic visit. In this case report, we review the key characteristic elements of rhinolithiasis presentation, and in doing so, we reveal the limitations inherent to telehealth evaluations, and the considerations needed to be taken into account by providers evaluating intranasal lesions. Specifically, in-person assessment with a detailed endoscopy is critical as part of the complete workup of nasal cavity lesions.

BACKGROUND
Langenbach (1820) first described paranasal sinus mucoceles under the name of hydatids. Roulette (1909) introduced the name mucocele. Paranasal sinus mucocele is the accumulation of mucus secretions and exfoliated epithelium in the sinuses, causing enlargement of the sinus walls. It is considered a cystic, dilatation-eroding lesion. However, the mucocele often occurs as a localized mass, causing bone erosion and displacement of surrounding structures. If left untreated, a nearby mucocele in the brain can become infected and lead to death. Frontal sinuses are often involved; sphenoid, ethmoid, and maxillary mucoceles are rare. Mucoceles usually result from sinus ostium obstruction due to infection, fibrosis, inflammation, trauma, surgery, or obstruction by tumors such as osteomas. Of all causes, patients most often present with cranio-facial trauma (82.97%) and the most common mechanism is human aggression (90.85%).
CASE PRESENTATION
This 30-year-old male patient presented with a frontal head swelling of one year duration that started after he sustained a stick injury on the frontal head one year ago, and he has an associated frontal headache for one year. There was a 4x5cm frontal, firm, palpable, non-tender lesion extending from the nasion to the frontal head. On the brain CT scan, there was frontal bone erosion at multiple sites with partial frontal sinus opacity, an externally growing mass, and an old frontal sinus fracture noted. Bifrontal craniotomy and bilateral frontal sinus cranialization were done, and the patient was discharged on the third day and seen a month later with complete improvement from headache and swelling.
CONCLUSION
The incidence and pathophysiology of posttraumatic frontal sinus mucoceles are not known yet. The surgical management of mucocele demand a multidisciplinary team involving neurosurgeons, ear nose and throat surgeons, oral and maxillofacial surgeons, ophthalmologists and plastic and reconstructive surgeons. By treating the primary cause, frontal sinus fracture at contact, this case report aims to raise awareness of and prevent frontal sinus mucocele and related complications.

Osteomas are benign lesions that arise from the proliferation of either cancellous or compact bone. They can be categorized as extra-skeletal, peripheral, or central. Extra-skeletal soft tissue osteomas often develop within muscles, while peripheral and central osteomas emerge from the periosteum and endosteum, respectively. Osteomas are usually asymptomatic and rarely affect the jaws. In the mandible, they typically occur in the posterior regions. In this report, we present the case of a 46-year-old female with a mandibular peripheral osteoma located in the anterior region and treated by total resection via median cervicotomy.
