Unexpected Tumor in an Elderly Patient: Nasopharyngeal Angiofibroma.

Although nasopharyngeal angiofibroma is an expected tumor in adolescent males, it is uncommon in the elderly. Because of its high vascularity or bleeding during biopsy, surgical resection can be life threatening. Therefore, nasal angiofibroma should be kept in mind in existing masses especially in elderly patients and support should be obtained from imaging methods.

Nasopharyngeal Synovial Sarcoma; Report of A Rare Case.

Synovial sarcoma is a soft tissue tumor originating from mesenchymal precursor stem cells. It is usually seen in young males and lower extremities. It is only seen in 10% of head and neck region and nasopharynx which is a very unexpected location. We report a rare case treated with radiotherapy and chemotherapy.

Bilateral Masticator Space Metastasis of Breast Cancer Mimicking Abscess.

Metastasis to the masticator space and mandible is very rare. The most common origin in women is breast cancer. Cystic metastases may radiologically mimic abscess. Definitive diagnosis can be made histopathologically. The prognosis of these patients is very poor and early diagnosis is important. Therefore, metastasis should be considered in the differential diagnosis of oral lesions.

Cerebellar cavernous angioma associated with developmental venous anomaly presenting as a cerebellopontine angle neoplasm in CT scan.

Association of developmental venous anomaly (DVA) and cavernous malformation (CM) of the posterior fossa is rare. If bleeding occurs, it must be assigned to the CM. Developmental venous anomalies, considered as normal vascular variation, are rarely symptomatic. Indeed, the CMs are true malformations and have a high bleeding potential.

Evaluation of anterior and middle cranial fossa intraosseous arachnoid granulations with 3D T2-SPACE sequence.

OBJECTIVES: Arachnoid granulations (AG) can be located anywhere outside the dural sinuses. Their presence is thought to be associated with idiopathic intracranial hypertension (IIH) and cerebrospinal fluid (CSF) leaks. It was aimed to evaluate the intraosseous AGs located in the middle and anterior cranial fosses in detail with three-dimensional T2-SPACE (Sampling Perfection with Application optimized Contrasts using different flip angle Evolution-Siemens) imaging and to investigate their clinical significance. MATERIALS AND METHODS: Sixty-five intraosseous AG of 46 patients were included in this retrospective study. The highest diameter, bone indentation degree (in the inner tabula, diploe distance, reaching and exceeding the outer tabula), content (CSF/+parenchyma) of each AG were evaluated by 2 experienced radiologists. In addition, the presence of other MRI findings supporting IIH was examined. RESULTS: Additional signs of IIH were detected in 25 patients, and they were statistically significantly more common in the middle cranial fossa. Parenchymal herniation (in four patients) was more common in the young population. CONCLUSIONS: Intraosseous AGs can be evaluated in detail with T2-SPACE imaging. Determining intraosseous AG is very important both as an indicator of IIH and in terms of its content. T2-SPACE imaging is superior to CT and conventional sequences in this regard.

An Unusual Cause of Hearing Loss: Incudal Osteoma.

Osteoma is common in the temporal bone but extremely rare in the middle ear cavity and incus. Computed tomography plays an important role in the diagnosis of this slow growing benign osseous mass. The treatment of this lesion, which usually causes conductive type hearing loss, includes follow-up and surgery according to the patient's condition.

Two Extremely Rare Case of Carcinosarcoma Ex Pleomorphic Adenoma.

Carcinosarcoma ex pleomorphic adenoma (CCPA), also known as true mixed malignant tumor, is an extremely rare high-grade aggressive tumor. The histopathologic examination is the gold standard for diagnosis and radiologic imaging also plays an important role. CCPA should be considered in the differential diagnosis of salivary gland tumors when there are findings suggestive of malignancy such as necrosis and diffusion limitation on imaging.

Intense Soft Tissue Calcification of the Head and Neck Following Tracheostomy.

ABSTRACT: Dystrophic calcification is the accumulation of calcium salts, especially calcium phosphate, which can occur anywhere in the body. Unlike other heterotopic calcifications, it occurs in damaged tissue when there is no calcium imbalance. The most common sites are the heart muscle and valve and it is rarely seen in the head and neck region. It can appear by any cause of soft tissue degeneration such as trauma, infection, inflammation, and neoplasia. It is not symptomatic unless a dystrophic calcification mass is present and is usually detected incidentally. Determination of the etiology plays an important role in the planning of the treatment so that the patient's history, laboratory findings, and imaging methods are very important.

Rare Cause of Blurred Vision: Unilateral Primary Dural Ectasia of the Optic Nerve Sheath.

ABSTRACT: Dural ectasia, also known as meningocele of the optic nerve sheath, is a rare benign pathology. Magnetic resonance imaging has a great role in the diagnosis of this condition, which has nonspecific symptoms such as progressive blurred vision. It is observed as cerebrospinal fluid accumulation within the expanded nerve sheath around the optic nerve. Treatment is planned after differential diagnosis of other pathologies such as mass and inflammation in addition to diagnosis with magnetic resonance imaging. Medical treatment is usually sufficient, and surgical treatment is planned for progressive patients.

Unilateral Vision Loss Due to Isolated Onodi Cell Mucocele.

ABSTRACT: Onodi cell mucocele is a rare, benign, cystic, destructive and expansive lesion. While the sphenoid sinus mucocele is 1% to 2%, onodi cell mucocele is very rare. Because of its direct mass compression effect, its proximity to the orbital apex may cause many symptoms such as loss of vision, eye movements, and exophthalmus. Imaging methods have an important priority in diagnosis. It also plays a crucial role in planning treatment quickly and guiding the surgeon. Surgical excision is performed in the treatment, usually with an endonasal approach.
