Dentigerous cysts are seen in the maxillary canine and third molars. We report a case of dentigerous cysts invading the maxillary sinus, which was managed surgically by endoscopic‐assisted transantral and transnasal approach.

Computerized Tomography(CT) scan plays an important role in the diagnosis and treatment of sinus and skull base lesions. The CT image distinctly provides detail of bony anatomy, anatomical variation, and the extent of diseases, and differentiates between inflammatory, benign, and malignant sinus and skull base pathology.1 It is an important aspect of imaging that helps not only the diagnostic role but also rules out other sinus pathology and helps in designing the surgical plan by 3D-MPR  and 3D VRT CT scan. Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases. It can be associated with sinusitis. The patient may present either with a unilateral headache that is difficult to differentiate from a migraine or often no symptoms which are diagnosed by chance during a radiological examination. Here we present a case of a 42-year female present with left frontal headache and facial fullness treated with endoscopic and open approaches which were designed by CT paranasal sinus 3-D multiplanar reconstruction(3D-MPR) and from 3-D MPR and volume rendering technique(3D VRT).

Female, 66 years old with a chief complain of shortness of breath and lump over her neck since 6 month. Neck USG showed enlarged right lobe of thyroid gland with hyperechoic nodules. FNAC confirmed anaplastic carcinoma of thyroid. patient underwent chemotherapy using doxorubicin as agent of choice. She had difficulty in breathing and she kept on high flow of oxygen, even after she had stridor and planned for tracheostomy. MRI revealed heterogeneously enhancing mass (9.6*6.5*10.5 cm) replacing right lobe of thyroid, and extending superiorly till the level carotid bifurcation and inferiorly superior mediastinum. Lesion is partially encasing trachea and laryngeal airway, posteriorly extending into prevertebral space and anteriorly invading strap muscles and sternocleidomastoid muscle. Now it become very difficult stage. She transfers to ICU. intubation tried but failed. As mass was just anterior to trachea and difficult to do tracheostomy without intubation. all hope failed and she put continue to high flow of oxygen.

Approximately one to 10% of patients with Human Immunodeficiency virus (HIV) infection associated with salivary gland disease. The presence of Benign lymphoepithelial cyst (BLEC) in the parotid gland is an indicator of HIV Infection. The diagnosis is usually based on a clinical course and HIV confirmatory blood testing. We have reported a case of a 35 years old Nepalese male patient with swelling of the bilateral parotid glands and HIV associated BLEC confirmed by Rapid diagnostic test kit (Determine unigold stat pack).

Background: Foreign body ingestion frequently occurs in the extreme of ages. Meat bolus, fishbone buried in the food, and sharp bone are the common ingested foreign bodies among adults. The normal ligament and bony structure start to ossify after the third decade of life and mimic foreign bodies. Ossified thyrohyoid ligament, cricothyroid ligament, cornu of hyoid bone may be misdiagnosed as a foreign body in the aerodigestive tract. Case presentation: We describe a 54 years female who presented with painful swallowing for two days after eating chicken bone at Emergency Department. X-ray soft tissue neck lateral view showed a radiopaque shadow in front of the C3-C4 region. The patient underwent rigid esophagoscopy, however, a foreign body could not be found at the pharynx. Computerized Tomography (CT) shows the same hyperdense shadow at the same location as seen in the x-ray. Furthermore, Magnetic resonance imaging (MRI) scan was done to localize the exact site of the foreign body, but the patient was a case of thyrohyoid calcification rather than foreign body in the esophagus. Conclusion: Difficulty arises for the surgeons when a foreign body is not found during rigid esophagoscopy. It is important to reassess and locate the foreign body by imaging. The calcified ligament can mimic a foreign body in the neck. MRI confirms the diagnosis which may be misguided by X-ray and CT-scan.
