For a local field F with finite residue field, we count close vertices in the affine buildings of SLn(F ) and Spn(F ), addressing a question of [6]. In the case of SLn(F ), we give an explicit formula for the number ωn of vertices close to a given vertex. We establish the conjecture following Proposition 3.4 of [6] relating ωn and the number of chambers containing a given vertex. We give analog...

A solitary erythematous nodule on the arm A 31year old Kuwaiti female patient presented with a solitary skin lesion on the left arm since 1 year. The lesion started as a small red lesion that slowly progressed into a large nodule with erythematous halo. The lesion was painless and no other symptom was reported. There was no previous history of similar lesion and there was no history of any syst...

OBJECTIVE This study was designed to assess the ability of radiologists to accurately detect calcification within a solitary pulmonary nodule with chest radiography. MATERIALS AND METHODS Thirty-five solitary pulmonary nodules that were examined by both posteroanterior and lateral chest radiography and on thin-section CT were retrospectively identified. Fourteen radiologists blinded to the re...

Objective. This was a comparative study between FNAC and thyroid scan used to diagnose the solitary thyroid nodule and histopathology was used as gold standard to compare the results of both modalities. We hypothesized that Fine needle aspiration cytology and thyroid scan diagnose solitary thyroid nodule (STN) as accurately as histopathology. Materials and Methods. This study comprised of 50 pa...

  Solitary pulmonary nodule (SPN) is a frequent finding on the chest x-ray and computed tomography. Nuclear medicine techniques play an important role in the diagnosis and management of SPN. In the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (PET) using 18-F-FDG, and 11-C-Methionine, and single photon em...

A solitary pulmonary nodule (SPN) is radiologically defined as an intraparenchymal lung lesion that is < 3 cm in diameter and is not associated with atelectasis or adenopathy. Lung lesions > 3 cm in size are defined as lung masses. A solitary pulmonary nodule is noted on 0.09 to 0.20 per cent of all chest radiographs. An estimated 150,000 such nodules are identified each year. Ninety per cent o...

One hundred and thirty-one consecutive requests for thyroid scintigraphy were analysed to assess their diagnostic contribution to the subsequent medical management of the patient. Forty one per cent of requests were to investigate the presence of a clinically detectable solitary nodule and, of these, one fifth had hot nodules. Diffuse goitres accounted for 38% of all referrals, but in only two ...

The workup and management of the solitary pulmonary nodule is an increasingly common and confounding clinical problem for which a uniformly accepted approach has yet to be established. Conventional radiologic literature has suggested a number of imaging characteristics of nodules such as size, cavitation, growth rate, and margin morphology to guide the physician in clinical management. More rec...

Metastatic neoplasms of the thyroid are uncommon when compared to primary tumors of the gland. Renal cell carcinoma (RCC) is a highly aggressive tumor of the urinary system. It can spread all over the body. Isolated solitary metastases of RCC to the thyroid are very rarely observed. A 64-year-old woman with a history of left radical nephrectomy for RCC, was referred to our clinic with palpable ...

BACKGROUND Differential diagnosis of hypokalemia and adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome often presents challenging in endocrinology and requires careful clinical, biochemical, radiological, and pathological investigations. Hypokalemia is a common abnormality and systematic approach is required to avoid delays in diagnosis of important underlying causes. CASE SUMMA...
