Solitary fibrous tumour (SFT) is an uncommon type of spindle cell tumour that affects soft tissues. Due to the rarity of spinal SFTs, they are often overlooked by healthcare providers, leading to frequent misdiagnosis. The clinical signs of spinal SFT are not specific and can vary based on tumour size and location.

Foreign body aspiration is a significant cause of respiratory distress in geriatric patients, often leading to severe complications if not promptly identified and treated. Dental materials account for approximately 15-20% of foreign body aspirations in adults, with symptoms that can include dyspnea, localized wheezing, and, in some cases, cyanosis and pneumonia. We report the case of a 60-year-old man who aspirated a dental crown, resulting in shortness of breath.

The anatomy of the sural nerve is highly variable, and the nerve can present injuries of various etiologies, including iatrogenic injury during surgery. Precise knowledge of the course and morphology of the sural nerve is valuable, and the ability to assess the nerve properly before surgery increases the postoperative success rate, as well as facilitating the execution of nerve conduction studies and biopsies. The purpose of this article is to describe and illustrate the anatomy of the sural nerve, as seen on ultrasonography, which is a practical and economical imaging method.

Introduction: Cri Du Chat Syndrome (CdCS) is an autosomal genetic disorder involving the complete or partial deletion of the short arm of chromosome 5 (5p). The size of the CdCS deletion ranges from approximately 10-45 Mb.

Clinical Case: Female patient, one year and three months old, presents hyperextension of the knees.

The painful Os peroneum syndrome is subdivided into acute and chronic cases. The acute presentation is usually caused by trauma, most commonly a supination or inversion of the ankle, which consequently can lead to a fracture of the Os peroneum or even a rupture of the peroneus longus tendon. Furthermore, its chronic presentation comes as a result of recurrent foot injuries or even recovery from a fracture with calcification remodeling of this sesamoid bone.

This study aimed to systematically review the highest-quality evidence regarding the cutoff value in kPa for the diagnostic accuracy of ultrasound-based liver elastography in comparison with reference standards, including magnetic resonance imaging (MRI), computed tomography, and liver biopsy. In addition, we assessed the presence of hepatocellular carcinoma (HCC) and its associated implications in clinical and diagnostic contexts. We conducted a search using Medical Subject Headings across PubMed, Embase, Cochrane Library, Web of Science, Scopus, and Lilacs for articles published up to June 6, 2024.

Progressive supranuclear palsy (PSP) and multiple system atrophy (MSA) are neurodegenerative disorders characterized by parkinsonian symptoms. PSP typically presents with supranuclear gaze palsy, postural instability, and subcortical dementia, while dysautonomia and cerebellar signs are hallmark features of MSA. We report the case of a 77-year-old male patient with a four-year history of progressive parkinsonian symptoms that have shown poor response to treatment.

Damage to the sural nerve can cause sensory injuries, ranging from numbness to severe neuropathic pain. Conditions like ankle arthrosis and rheumatoid arthritis can compress the nerve, leading to pain and numbness. Sural nerve entrapment, although rare, can result in chronic calf pain, especially in athletes.

The thenar motor branch (TMB) of the median nerve exhibits significant anatomical variability, making it particularly vulnerable to iatrogenic injury during procedures such as carpal tunnel surgery. Understanding the diverse courses and origins of the TMB is critical for minimizing surgical complications. Such knowledge not only aids in preoperative planning but also enhances the accuracy of nerve conduction tests, contributing to improved postoperative outcomes.

Pronator teres syndrome is characterized by compression of the median nerve, leading to dysfunction of the affected limb. Median nerve entrapment causes paresthesia, changes in sensitivity, and loss of strength in the fingers, in addition to causing loss of hand dexterity. The diagnosis of pronator teres syndrome is complicated, due to its similarity with other neuropathies of the median nerve.

In the clinical evaluation of upper extremity embolism cases, the anamnesis should focus on identifying potential triggering risk factors. The physical examination may reveal sensory deficits, aiding in the determination of ischemia stages. Imaging diagnosis is crucial, with computed tomography (CT) angiography being the preferred examination due to its ability to provide detailed information about arterial anatomy across multiple planes and clear visualization of adjacent structures.

Edema of the psoas major muscle can indicate various pathologies, such as infection, malignancy, and trauma, but it can also result from benign causes like delayed-onset muscle soreness (DOMS). This article presents the case of a 44-year-old female patient who developed DOMS in the psoas major after participating in an intense abdominal workout. The patient reported hip pain that began a day after the workout, which was confirmed by magnetic resonance imaging (MRI) revealing significant edema in the psoas major muscles, particularly on the right side.

The neuropathic compression of the tibial nerve and/or its branches on the medial side of the ankle is called tarsal tunnel syndrome (TTS). Patients with TTS presents pain, paresthesia, hypoesthesia, hyperesthesia, muscle cramps or numbness which affects the sole of the foot, the heel, or both. The clinical diagnosis is challenging because of the fairly non-specific and several symptomatology.

The coracoclavicular joint is a diarthrodial synovial joint that is eventually located between the upper surface of the horizontal part of the coracoid process and the conoid tubercle of the clavicle, and is considered an unusual anatomical alteration. The coracoclavicular joint has a low prevalence and can be diagnosed by imaging tests - radiography and computed tomography. Treatment can be performed both conservatively and surgically.
