Lomber spinal anjiyolipom: a case report

Lumbar spinal angiolipomas are rarely seen tumors which present with progressive spinal cord and/or root compression symptoms. Definitive diagnosis with magnetic resonance imaging (MRI) is possible because of their unique signal characteristics. However, probable misdiagnosis is likely due to the infrequency of these tumors. This article reports the case of a 53-year old woman with progressively worsening low back and hip pain in last 6 months. MRI demonstrated a sharply demarcated extradural mass which was hyperintense to cerebrospinal fluid and hypointense to epidural fat on T1-weighted images. The signal was suppressed in fatsaturated images and the mass showed diffuse enhancement after contrast administration

Diagnostic value of acustic radiation force impulse imaging in the assessment of salivary gland involvement in primary Sjogren's sydrome

Aims: The aim of this study is to investigate the diagnostic value of Acoustic Radiation Force Impulse (ARFI) imaging in the assessment of salivary gland involvement in primary Sjogren's syndrome (pSS). Material and methods: Twenty five patients with pSS and 25 healthy volunteers were included. First, echostructures and the thickness of the submandibular and parotid glands were evaluated by B-mode ultrasonography. Then, ARFI imaging with Virtual Touch Quantification (R) was performed. Ten independent shear wave velocity measurements were taken from each gland. Finally, the mean shear wave velocity (SWV) values were calculated, and used for further analysis. Results: The mean SWV values of parotid and submandibular glands were significantly higher in the pSS patients than in the healthy control group (p 0.005). Conclusions: Our findings indicate that ARFI imaging may provide a non-invasive, simple and fast means of assessment of glandular impairment as an alternative test when other salivary gland tests are inconclusive or cannot be performed. ARFI may be a valuable adjunct for the clinical diagnosis of pSS

Value of shear wave elastography by virtual touch tissue imaging quantification in patients with diffuse thyroid gland pathology

Background/aim: This study was performed to assess the diagnostic accuracy of shear wave elastography by virtual touch tissue imaging quantification in patients with diffuse thyroid gland pathology and to differentiate Graves' disease from Hashimoto's thyroiditis. Materials and methods: Thirty patients with Hashimoto's thyroiditis and 22 patients with Graves' disease were evaluated with conventional ultrasonography and shear wave elastography by virtual touch tissue imaging quantification. Thirty healthy participants formed the control group. Ten elastographic measurements of each thyroid lobe were performed in all three study groups. The mean shear wave velocity was calculated and compared between the patients and controls. Results: The mean shear wave velocity of the controls (1.92 +/- 0.14 m/s) was significantly lower than that of the patients with Graves' disease (2.71 +/- 0.22 m/s) and Hashimoto's thyroiditis (2.50 +/- 0.20 m/s). Patients with Graves' disease had significantly higher shear wave velocities than those with Hashimoto's thyroiditis (P < 0.001). Conclusion: Shear wave elastography by virtual touch tissue imaging quantification can be used to discriminate a normal thyroid gland from diffuse thyroid gland pathology after conventional sonography and may assist in the diagnosis of Graves' disease and Hashimoto's thyroiditis
