In 5% of cases in the nasopharynx of an adult can be found a neoplasm with benign or malignant nature. Clinical manifestations of such pathology are next: persistent dysfunction of the auditory tubes, nasalness and postnasal drip syndrome. Endoscopy of the nasopharynx, computed tomography of the sinuses and magnetic resonance imaging of the head are the main diagnostic criteria for detecting neoplasms in this area. The tactics of treatment depends on the dysplasia type of the pathological process and varies from endoscopic one-stage resection to chemoradiation treatment. Using the example of two clinical cases, we will consider an algorithm for diagnosis and treatment the patients.

Pulmonary Arterial

The most common cause of pulmonary artery filling defects on computed tomography pulmonary angiography or magnetic resonance imaging is pulmonary thromboembolism, but not infrequently, the presentation of this finding lacks specificity. Given that the morbidity and mortality associated with pulmonary thromboembolism is high, proper diagnosis of the condition is essential. Unusual or more rarely encountered etiologies must be considered when clinical manifestations and imaging findings are inconsistent. With this review, our purpose is to describe possible causes of pulmonary arterial filling defects. We aim to provide clinicians with a comprehensive list of differential diagnoses to facilitate a measured approach to the assessment of pulmonary arterial filling defects on computed tomography pulmonary angiography or magnetic resonance imaging.

In recent years, it has become apparent that the incidence of diseases of the hypothalamic-pituitary system is extremely high. The clinical manifestations of diseases such as acromegaly, Itsenko Cushing's disease, primary hyperprolactinemic hypogonadism are considered to be well known [8, 9, 32, 45]. However, to select the optimal method of treatment in each specific clinical situation, it is imperative for the clinician to obtain information about the state of the main structural link of the pathological process - the pituitary gland

The incidence ranging of the dermoid and epidermoid cysts on the head and neck, from 1.6 to 7.0%, and they represent less than 0.01% of all oral cavity cysts. Histologically, they can be further classified as epidermoid, dermoid or teratoid. We analyzed two rare cases of large epidermoid cysts of the floor of the mouth, with sublingual as well as submental component resembling plunging ranula. Two female patients (age 15 and 16 y. o.), who’s had sublingual and submental swellings of oral floor with breathing and swallowing difficulties. The suspected clinical diagnosis of the sublingual dermoid or epidermoid cysts were supported by the radiological finding after performing ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI). On the radiological investigation the differentiation between epidermoid cysts, ranulas, cystic tumours, mucous extravasation phenomena and hygromas sometimes indistinguishable, leading in the determination of internal component differentiation and has pathognomonic signs to differentiate. The lesions were surgically excised using an intraoral approach. Microscopic examinations revealed a dermoid cyst of the epidermoid type.

Case reports detailing diagnosis and effective treatment of pisotriquetral loose bodies are scarce. This article describes an even rarer case of bilateral pisotriquetral joint loose bodies, explores the relative diagnostic roles of magnetic resonance imaging versus computed tomography, and outlines effective strategies used for the management of this condition drawn from the literature and our own experience.

Cardiac Myxomas

Aim. To determine the algorithm of in vivo diagnosis and surgical treatment of cardiac myxomas. Methods. Summarized was the experience of diagnosis and surgical treatment of 65 cases of cardiac myxomas. Examination of patients included electrocardiography, phonocardiography, radiography, angiocardiography, selective coronary angiography, two-dimensional transthoracic echocardiography, transesophageal echocardiography, computed tomography and magnetic resonance imaging with contrast, a biopsy, and a morphological study. Results. Among the examined patients (mean age 42.4±1.5 years) cardiac myxomas were diagnosed, which were localized in the left and/or right chambers of the heart. All patients underwent surgery. The tactics of surgical treatment were dependant on the tumor size, its mobility, involvement of the valve apparatus and conduction pathways of the heart into the pathological process, and concomitant diseases. The prognosis of the natural course of cardiac myxomas is unfavorable. In the diagnosis of space-occupying lesions (myxomas) of the heart chambers, which are often combined with valvular pathology, the most informative are echocardiography, computed tomography and magnetic resonance imaging. The final verification of the diagnosis should be made using emergency and routine pathological studies. Conclusion. Timely surgical removal of the myxomas with simultaneous correction of the concomitant cardiac pathology makes it possible to restore the intracardiac haemodynamics and to prevent thromboembolic complications.

Abstract BackgroundHemangioblastoma in the kidney is rare. Although a few renal hemangioblastoma cases have been reported, the content of these articles mainly focused on clinical and pathological research, with minimal descriptions of radiologic findings. Moreover, there are no descriptions of magnetic resonance imaging with enhancement for this condition. We herein report two cases of renal hemangioblastoma with computed tomography and magnetic resonance imaging findings.Case presentationTwo patients presented to our institution due to dull pain of the left abdomen, and a mass in the left kidney was found by ultrasound examination in each case. They had no special family history. Physical examination revealed no obvious tenderness or percussion pain in the renal region and ureteral walking area, and there was no obvious mass. Routine blood and urine tests were normal, and serum tumor markers were negative. No obvious lesions were found on imaging of other body parts. Similar radiologic findings were observed in both cases and mimicked those of cavernous hemangiomas of the liver, including peripheral nodular enhancement in the corticomedullary phase, progressive centripetal enhancement in the nephrographic and delayed phases, and occasional complete “filling in” in the delayed phase. Given the suspicion for renal cell carcinoma, both patients underwent partial nephrectomy. The pathological results showed renal hemangioblastoma.ConclusionsRenal hemangioblastoma is a rare benign tumor that is easily misdiagnosed as clear cell carcinoma. Characteristic computed tomography and magnetic resonance imaging manifestations may improve preoperative diagnostic accuracy to avoid surgery or indicate nephron-sparing surgery.

The aim of the review was to summarize information on clinical manifestations, diagnostic features, as well as methods for correction of scar defects after cesarean section (CS) outside pregnancy. Lack of the scar after CS, niche, isthmocele are a myometrium defect in the area of scar after CS, which is most often detected by ultrasound, sonohysterography or magnetic resonance imaging and is manifested by postmenstrual bleeding from the genital tract. In some cases, it can cause menorrhagia, dyspareunia, pelvic pain, infertility, uterine rupture during subsequent pregnancy and childbirth. Conservative therapy or surgical treatment with laparoscopy, laparotomy or vaginal approach is carried out depending on the symptoms, size of the defect, the thickness of the residual myometrium, as well as the womans reproductive plans.
