Radiological Imaging of Rare Intracranial Complications Secondary to Otitis Media and Mastoiditis.

Acute otitis media used to cause fatal results because of its intracranial complications before the introduction of potent and effective antibiotics. After the introduction of antibiotics, complications have started to be observed more frequently as a result of chronic otitis media and especially in children. Because clinical findings changed and became indistinct, the diagnosis of otitis and mastoiditis has been made occasionally with imaging findings only after complications occurred. Multidetector computed tomography and magnetic resonance imaging are efficient and sufficient methods in the rapid diagnosis and should be immediately referred methods.

Aberrant Internal Carotid Artery in the Tympanic Cavity.

OBJECTIVES: Presence of aberrant internal carotid artery (ICA) in the tympanic cavity is a very rare case and therefore the diagnosis is a challenge. Here, the authors aimed to address the importance of the diagnosis since the intervention to the middle ear and implants is increasing in number and this condition may lead to life-threatening bleeding. METHODS: Between 2012 and 2016, among the patients referred to the authors' Radiology Department from the Department of Otolaringology for the evaluation of the temporal region for various indications, the authors reported this anomaly in 6 patients and multidetector computerized tomography of these 6 patients and magnetic resonance imaging of 2 were assessed in detail. RESULTS: The mean age of the 6 patients was 28.8 and aberrant ICA abnormality was observed in 2 patients bilaterally and 4 patients unilaterally on the right side. In 1 patient ICA was not totally regressed and observed as hypoplastic. In one of the patients, dehiscence was evident between ICA and the cochlea. Moreover, in 1 patient the contralateral ICA was not observed. CONCLUSION: Although rare, aberrant ICA is an abnormality that should be kept in mind by the clinicians and the radiologists, since it leads to abundant bleeding when undiagnosed before the surgical interventions.

Two cases with giant pseudo-aneurysm of vertebral artery secondary to shrapnel injury.

INTRODUCTION: Due to their locations, vertebral arteries (VA) are structures that are rarely injured after traumas. Formation of vertebral pseudo-aneurysm (PA) because of pieces of shrapnel is also rare. It causes clinical findings like cervical mass after the injury CASES PRESENTATION: Two Syrian 12- and 17-year-old male patients were admitted to the Department of Ear, Nose and Throat with the complaint of swelling in the left lower cervical region. In their USG examination which was ordered to investigate the cervical lesion, a lesion consistent with PA which shows a prominently thick wall structure due to circumferential thrombus formation and fibrotic tissue, chaotic flow, and ying-yang appearance in the centrally located cavity of the lesion in a color Doppler examination was detected. Later, multi-detector computed tomography angiography (MDCTA) was planned to demonstrate pseudo-aneurysms (PAs). CONCLUSION: Because there was no report on the development of giant pseudo-aneurysms secondary to shrapnel injury to date and because we thought these cases are demonstrative, we found the cases suitable for presenting as case reports.
