“…Second, we were unable to confirm that lesions smaller than 5 mm could be reliably detected using HASTE DWI because most of the detected cholesteatomas were larger than 5 mm. However, as with other studies, we believe that smaller cholesteatomas have no short-term prognostic impact (9,11) and may be detected during follow-up visits with repeated MRI.…”

“…HASTE DWI has shown mixed results in the detection of cholesteatoma in past studies. Although Plouin-Gaudon et al (9) reported relatively low sensitivity, specificity, NPV, and PPV (62%, 88%, 89%, and 58%, respectively), most studies have reported a very high diagnostic performance for HASTE DWI that often reaches 100% for all four statistical measures (8). De Foer et al (19) have reported that the HASTE DWI detection limit for a cholesteatoma is as low as 2 mm; EPI DWI had previously set the limit of detection at 5 mm.…”

“…Dhepnorrarat et al (8) stated that HASTE DWI techniques would be useful for patients with a discharging ear or for ruling out recurrent cholesteatoma within the middle ear or mastoid cavity but not in a dry auto-evacuating retraction pocket. Although HASTE DWI avoids bone-air artifacts in zones such as the tegmen, the spatial resolution remains poor for very small or thin lesions (9). De Foer et al (21) also noted motion artifacts on HASTE DWI images.…”

“…Delayed postcontrast T1 spin-echo sequences improve the diagnosis of recurrent cholesteatoma and allow differentiation between scar tissue, which shows delayed enhancement, and cholesteatoma, which does not show delayed enhancement; conversely, inflammatory tissue displays early enhancement (7). However, these sequences do not provide the diagnostic performance necessary to eliminate the need for second-look surgery (7)(8)(9)(10)(11). Growing data suggest that DWI, particularly Half-Fourier acquisition single-shot turbo spin-echo (HASTE) DWI, yields better diagnostic performance for the detection of cholesteatomas (8,11).…”

“…In such cases, middle ear cholesteatoma may be frequently found. CT scan is very efficient in preoperative diagnostic evaluation of cholesteatoma, with positive predictive value of 75% [21] . The clinical presentation of acute mast-oiditis in patients with evident middle ear cholesteatoma on CT scan should not be considered as acute mastoiditis itself, since it is caused by a chronic disease of the middle ear or a congenital malformation.…”

OBJECTIVE: Acute mastoiditis is serious otological condition which may cause difficult, sometimes fatal complications. The aim of the study is to present our experiences in diagnosis and treatment of acute mastoiditis in children. MATERIALS and METHODS:Medical records of 52 children with diagnosis of acute mastoiditis were reviewed retrospectively. Data on clinical presentation, laboratory tests, microbiological and radiological features, prehospital treatment and delay in making the diagnosis, hospital treatment and outcome were analyzed. A relationship between white blood cell count or level of C-reactive protein and therapeutic protocols was investigated. RESULTS:All children were admitted as emergency patients and were treated with intravenous antibiotics. Almost 15% of patients were not examined by a doctor prior to hospitalization. The conservative treatment was successfully conducted in 15% of patients. One-third of the patients were recovered after myringotomy. Almost a half of the patients underwent surgical procedure such as antrotomy, mastoidectomy or tympanomastoidectomy. Computed tomography (CT) scan was done in patients with signs of developing complications and those with no improvement after the beginning of treatment. CONCLUSION:Acute mastoiditis is still persisting problem in our health care system. An early diagnosis and adequate treatment of acute mastoiditis is essential in order to prevent serious complications.

Recent developments in imaging techniques have made diffusion-weighted MRI more effective for detecting recurrent cholesteatoma. The major drawback of this technique, however, has been its poor anatomical and spatial discrimination. Fusion imaging using high-resolution CT and diffusion-weighted MRI appears to be a promising technique for both the diagnosis and precise localization of cholesteatomas. It provides useful information for surgical planning and, furthermore, is easy to use in pediatric cases.
