Magnetic resonance sialography findings of submandibular ducts imaging.

PURPOSE: We aimed to assess the problem solving capability of magnetic resonance sialography (MR sialography), a noninvasive method for imaging submandibular gland ducts and determining duct-related pathologies, by comparing diseased and healthy cases. MATERIALS AND METHODS: We conducted radiological assessment on a total of 60 submandibular glands (mean age 44.7) in 20 cases and 10 volunteers. MR sialography examinations were conducted with single-shot fast spin-echo sequence by using a surface coil placed on the submandibular gland. Each gland was evaluated in terms of the length, width and stricture of the main duct, as well as the difference between the intraparenchymal duct width, and the main duct width. Statistical analysis was performed. RESULTS: In the MR sialography the primary duct mean length was determined as 51 mm (40-57 mm) in all submandibular glands. On the MR sialography imaging, the visualization ratio of the ductal system of submandibular gland was evaluated in the cases and volunteers. CONCLUSION: MR sialography is an effective and a noninvasive method in imaging submandibular gland ducts, demonstrating the presence, location and degree of stricture/dilatation, and elucidating the disease etiology.

Bilateral Baxter's neuropathy secondary to plantar fasciitis.

BACKGROUND: Baxter's neuropathy is a nerve entrapment syndrome that results from the compression of the inferior calcaneal nerve. The causes of Baxter's neuropathy include altered foot biomechanics such as flatfoot, plantar calcaneal enthesophytes, and plantar fasciitis. Baxter's neuropathy and causative pathologies such as plantar fasciitis can be identified with the help of typical MRI findings. CASE REPORT: In this report, bilateral Baxter's neuropathy developed in a 42-year-old woman secondarily to bilateral plantar fasciitis. On MR images, fatty atrophy of the abductor digiti minimi muscles was found in both feet, revealing high-signal areas in the T1-weighted images and low-signal areas in the T2-weighted images. Additionally, findings of plantar fasciitis were observed in both feet. CONCLUSIONS: To the authors' knowledge, no case of bilateral Baxter's neuropathy secondarily to plantar fasciitis has been reported. Baxter's neuropathy and causative disorders are easily recognized with help of typical MRI findings. Selective fatty atrophy of the abductor digiti minimi muscle is the unique sign of this neuropathy. Recognition of unique MRI findings of this rare condition that can cause heel pain are important since they provide an effective treatment plan.

A prospective study of paranasal sinus osteomas in 1,889 cases: changing patterns of localization.

OBJECTIVES/HYPOTHESIS: We developed the largest paranasal sinus computed tomography (CT) scan study so far by including 1,889 cases to investigate the prevalence, localization, age distribution, and the secondary complications of paranasal sinus osteomas. STUDY DESIGN: Prospective study. METHODS: A prospective study was performed on 1,889 consecutive adult individuals who underwent paranasal sinus CT examinations with suspected sinus disease. RESULTS: The prevalence of paranasal sinus osteomas was determined to be 3%. Osteomas were located most frequently in the ethmoid sinuses. The size of the osteomas varied from approximately from 2 to 30 mm. Of the osteomas found, 37%were accompanied by pathological sinonasal findings. CONCLUSIONS: The prevalence of sinonasal osteoma in the paranasal sinus region detected by CT scan is supporting the literature, whereas the localization pattern challenges it.
