Here, we aimed to analyze the objective findings regarding peripheral nerve, neuromuscular junction, and muscle function using electrophysiology in patients with a previous COVID-19 infection.

Methods: All consecutive patients with a history of COVID-19 were questioned for post-COVID-19 duration-related neurological complaints via Composite Autonomic Symptom Score-31 (COMPASS-31), modified Toronto Neuropathy score (mTORONTO), and Fatigue Severity Scale (FSS).

Spinal Melorheostosis: A Rare Presentation.

Case: A 22-year-old female patient was referred to the orthopaedic department for further examination after a radiopaque area was observed in the T6 vertebra in her chest radiograph. Computed Tomography (CT) showed a sclerotic mass with smooth borders, involving the entire body of the T6 vertebra, left posterior elements, posterior of the rib past the left zygapophyseal joint, and a "flowing candle wax" image toward the T7 vertebra. Spinal melorheostosis was considered radiologically in the patient, but malignancy could not be completely excluded.

Significant Prostate Cancer in Patients with PI-RADS Category 3 Lesions: A Single-Center, Retrospective Cohort Study.

Purpose:  The Prostate Imaging-Reporting and Data System (PI-RADS) category 3 is the most ambiguous lesion with a variable clinically significant prostate cancer (CsPCa) detection rate. Prostate-specific antigen density (PSAD) has been investigated as an adjunctive factor to improve the diagnostic efficiency of PI-RADS categories. This study aimed to investigate the utility of PSAD as an adjunctive factor in predicting CsPCA risk in patients with PI-RADS 3 lesions.

Assessment of deep venous thrombosis in the lower extremity in Behçet's syndrome: MR venography versus Doppler ultrasonography.

Lower extremity venous thrombosis (DVT) is the most common vascular manifestation of Behçet's syndrome (BS). Currently, Doppler ultrasonography (USG) is the most commonly preferred imaging modality in the diagnosis and follow-up of patients with acute and chronic DVT. Magnetic resonance (MR) venography, a quick and a non-invasive imaging modality, is successfully used to detect DVT in various settings.

Bladder cancer in an inguinal vesical hernia.

A 60-year-old male patient presented with intermittent right-sided scrotal swelling for the last 4 months. On ultrasonography, a fluid-filled cavity extending through the right inguinal canal into the scrotum was noted with inferior displacement of the right testis. Multiple papillary hyperechoic lesions with internal vascularity on Doppler ultrasound were protruding into the fluid-filled cavity.

Amyloid Goiter: A Diagnosis to Consider in Diffuse Fatty Infiltration of the Thyroid.

An amyloid goiter is the presence of amyloid protein in the thyroid in sufficient amounts to produce enlargement of the gland, accompanied by fat deposition of varying extents. It can be seen in long-standing inflammatory disorders such as familial Mediterranean fever. Imaging findings depend on the amount of fat and amyloid deposition; however, the main imaging finding is diffuse fatty infiltration of the thyroid.

Penile masses: Shear Wave Elastography correlated with Magnetic Resonance Imagining. A two cases report.

Definitive diagnosis of penile masses usually depends on clinical symptoms and patient history but in some challenging cases the help of radiologic diagnostic tools is required. Although ultrasound is an effective tool for detecting penile masses, unlike magnetic resonance imagining, it is not able to differentiate benign and malignant pathologies. Shear wave elastography (SWE) is a novel method, which has the ability to differentiate malignant and benign tissues by giving quantitative information about tissue elasticity.
