Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo and has a lifetime prevalence of 2.4% in the general population. Benign paroxysmal positional vertigo is caused when calcium carbonate material originating from the macula of the utricle falls into one of the semicircular canals. Due to ...

There is a broad spectrum of benign disorders of the biliary system that resemble hilar cholangiocarcinoma (HCCA) in terms of clinical, pathologic, and imaging findings. No unifying features were found to characterize patients with benign hilar obstruction and distinguish these patients from those with cholangiocarcinoma. Imaging plays a vital role ...

Intraosseous leiomyomas are very rare. To the best of our knowledge, this is the first published case of primary intraosseous leiomyoma in a rib. This rare benign tumour should be included in the differential diagnosis of any relatively small intraosseous lesion with benign imaging findings, but with gradually worsening, long-standing ...

Benign paroxysmal positional vertigo is the most common peripheral cause of vertigo. Although its pathophysiologic mechanisms remain unclear, different locations have been attributed throughout the last century, from the days of Bárány. Disease was initially located by Dix and Hallpike in the utricle, but later, Schuknecht's works elicited the cupulolithiasis ...

A 50-year-old white Caucasian woman with previously diagnosed migraine was admitted with unilateral headache and anisocoria. An initial assessment revealed no cause for this abnormality and she was thought to have mydriasis in the context of migraine. However, failure of her symptoms and signs to resolve prompted further investigation and ...

Isolated amyloidosis of the lower urinary tract is rare. This report presents localised primary amyloidosis of the urinary bladder as a rare cause of macroscopic haematuria. Treatment of bladder amyloidosis mainly consists of controlling the haematuria. For small localised lesions, the favoured approach is transurethral resection (TUR) of the lesion.

The pharmacokinetic analysis of dynamic-contrast-enhanced (DCE) MRI data yields K(trans) and k(ep), two parameters independently measuring the capillary wall contrast reagent transfer rate. The almost universally used standard model (SM) embeds the implicit assumption that equilibrium transcytolemmal water exchange is effectively infinitely fast. In analyses of routine DCE-MRI data from ...

Benign metastasizing leiomyomas are rare tumors, which are typically found in the lungs and, thus, might be confused with leiomyosarcomas. Further, it is not clear whether the term "benign metastasizing leiomyoma" is a misnomer and whether these lesions actually represent low-grade malignant tumors that have a low proliferation index. Micro-RNAs ...

Several benign and malignant nonepithelial and stromal-like lesions arise in the prostate. Because such lesions are rare, their recognition is essential, because treatment and prognosis depend on an adequate pathohistologic classification. We report a case of an 83-year-old man with a stromal tumor of the prostate of uncertain malignant potential ...

ABSTRACT: A 62-year-old male presented with symptoms of urinary obstruction and elevated serum prostate-specific antigen level of 3.61 ng/mL. Prostate needle biopsies showed benign prostatic tissue with a focus of crowded glands with minimal cytological atypia, fairly well-circumscribed with infiltrative appearance of glands at the edges. This focus had both ...

Hepatic tuberculosis is a rare manifestation of extra-pulmonary tuberculosis. Hepatic tuberculous lesions are especially mimicking tumour-like mass or cystic lesions in the liver and so can be misdiagnosed with several diseases. Histopathological examination of the specimen is essential in the diagnosis for hepatic tuberculosis. In this report, two cases with ...

Prostatic enlargement due to benign adenomatous hyperplasia is very common in elderly males. However, benign mesenchymal tumors, especially true leiomyoma, are rare in prostate. True prostatic leiomyoma has been defined by Kaufman and Berneike as a smooth muscle tumor within the prostate or juxta-prostatic in position, devoid of glandular elements. ...

The morphologically heterogeneous (intra)ductal lesions of the prostate frequently present a diagnostic challenge, particularly when found within prostate needle biopsies. By current convention, all high-grade intra-acinar and intraductal neoplastic lesions of prostatic origin fall under the diagnostic umbrella term: prostatic intraepithelial neoplasm (PIN). Although a long-standing contentious issue, some lesions ...
