Concordance between a Mohs surgeon and a dermatopathologist in evaluating Mohs cryosections.

Background: Mohs micrographic surgery is the gold standard treatment for high-risk non-melanoma skin cancers. The success of Mohs relies on accurate histopathologic evaluation. Due to law restrictions in some European countries, Mohs surgeons are not permitted to report on histopathology; therefore, a pathologist evaluates the frozen sections.

[Tracheal bronchus which is characterized with persistent cough].

A 57-year-old man admitted to department of pulmonary medicine with a history of persistent cough. Computed tomography showed there was a right tracheal bronchus originated from 1/3 distal region of trachea. We reported this case because of the rarity of pulmonary anomaly.

Colour Doppler imaging of superior ophthalmic vein in thyroid-associated eye disease.

Purpose: One of the possible etiologies of proptosis in patients with thyroid-associated eye disease is stated to be passive orbital venous congestion caused by the occlusive and constrictive changes of the superior ophthalmic vein (SOV). In an attempt to clarify the validity of this claim, quantitative information on the flow velocity of the SOV was obtained by colour Doppler imaging in 24 patients with thyroid-associated eye disease and compared with data from the control group.

Methods: On clinical examination, ocular motility, proptosis, soft tissue involvement, and the presence of optic neuropathy were evaluated.

Magnetic resonance imaging and morphometric histologic analysis of prostate tissue composition in predicting the clinical outcome of terazosin therapy in benign prostatic hyperplasia.

Purpose: To determine whether magnetic resonance imaging (MRI) or quantitative color-imaged morphometric analysis (MA) of the prostate gland are related to the clinical response to terazosin.

Methods: Thirty-six male patients with symptomatic benign prostatic hyperplasia (BPH) with a serum prostate-specific antigen level of 4-10 ng/mL underwent MRI with body coil, transrectal prostate ultrasonography and biopsy prior to terazosin therapy. For MRI-determined stromal and non-stromal BPH, the ratio of the signal intensity of the inner gland to the obturator internus muscle was evaluated.

Radiology of an atypical fibro-osseous lesion confined to the nasal cavity.

Fibro-osseous lesions of the sinonasal region are relatively frequent, but those strictly confined to the nasal cavity are rare. We report an atypical fibro-osseous lesion in the nasal cavity and describe its radiological features. The differential diagnosis is discussed.

MR imaging and MR angiography in popliteal artery entrapment syndrome.

Popliteal artery entrapment (PAE) syndrome is an uncommon congenital anomaly seen in young adults causing ischemic symptoms in the lower extremities. It is the result of various types of anomalous relationships between the popliteal artery and the neighboring muscular structures. The purpose of this study was to define the role of MR imaging combined with MR angiography in the diagnosis of PAE cases.

Radiological follow-up in encapsulated intracerebral hematoma mimicking intratumoural bleeding.
