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.
