Giant Soft Tissue Hemangioma of the Neck with Laryngeal Extension.

Introduction: Soft tissue hemangiomas are among the most prevalent soft tissue tumors and can pose diagnostic challenges due to their propensity to extend into various regions. In our case, imaging studies facilitated effective characterization of the mass, and timely intervention with sclerotherapy enabled adequate initial control of the lesion. Subsequently, medical management with propranolol and a second scheduled surgical intervention with sclerotherapy contributed to a reduction in the lesion size, alleviation of symptoms, and improvement in prognosis.

Wandering Liver: A Case Report With Clinical and Radiological Insights.

Wandering liver (WL) is an exceptionally rare anatomical variant, scarcely described in the medical literature. This condition is characterized by hypermobility of the liver within the abdominal cavity, resulting from the weakening, laxity, or absence of the liver's suspensory ligaments. This case report describes a 28-year-old male patient with a history of Sashi-Pena syndrome who presented with chronic, nonspecific abdominal pain, in which cross-sectional imaging incidentally revealed WL.

Spleen anomalies and lesions in CT and MRI: essentials for radiologists and clinicians-a pictorial review.

The precise evaluation of splenic lesions using cross-sectional imaging presents a complex challenge due to the overlapping imaging characteristics of most splenic diseases and the absence of specific symptoms, complicating the diagnosis process. This pictorial review highlights the essential elements that should be included in a radiology report to interpret cross-sectional imaging studies of splenic lesions. To augment the diagnostic accuracy, we propose the implementation of a stepwise algorithmic approach.

Pulmonary Calcifying Fibrous Tumor in a Pediatric Patient: A Case Report.

A calcifying fibrous tumor (CFT), also known as calcifying fibrous pseudotumor, is an uncommon non-cancerous neoplasm usually located in the gastrointestinal tract. Its location in the lung is extremely rare, and only a few case reports have been published. This case report describes our diagnostic approach in a 9-year-old male patient with an incidental pulmonary mass.

Aberrant Right and Left Gastric Veins as a Cause of Hepatic Pseudolesions: A Report of Three Cases.

The complex structure of the liver and its elaborate hemodynamics can cause hepatic pseudolesions on contrast-enhanced imaging, making the interpretation of diagnostic liver imaging challenging. Aberrant gastric veins are rare; most of their epidemiology data comes from small single-center studies. While current literature suggests that pseudolesions originating from aberrant gastric veins mainly present as hyperdense defects, some cases can also show up as hypodense, as shown in these cases.

Odontogenic myxoma: A case report of a rare tumor.

Odontogenic myxoma is a rare and aggressive tumor. Identifying the tumor based on imaging characteristics can pose a challenge due to similarities in features with other tumors, such as ameloblastomas and aneurysmal bone cysts. We report a 33-year-old female who presented with a palpable, tender mass in the lower right jaw.

Prevalence and risk factors of unruptured intracranial aneurysms in ischemic stroke patients - A global meta-analysis.

Background: Unruptured intracranial aneurysms (UIAs) have an estimated global prevalence of 2.8% in the adult population; however, UIA was identified among more than 10% of ischemic stroke patients. Many epidemiological studies and reviews have pointed to the presence of UIA among patients with ischemic stroke; yet, the extent of this association is not fully known.

Traumatic scalp arteriovenous fistula post capillary implantation successfully treated using PHIL embolic agent.

Background: A traumatic arteriovenous fistula of the scalp due to hair transplantation (AVFHT) is a rare fistulous communication between branches of the arteries and draining veins in the scalp's subcutaneous tissue. Its incidence is unknown and its clinical manifestations may range from a pulsatile mass to seldom epilepsy. Surgery and interventional approaches (percutaneous and endovascular embolization) using coils and embolic agents such as Onyx have been used as treatment options.

Incipient Melanonychia: Benign Finding or Occult Malignancy? A Case Report of Subungual Melanoma.

Subungual melanomas are rare neoplasms that tend to debut as longitudinal melanonychia. They are primarily found in patients over 60 years of age and are usually diagnosed late, representing a diagnostic challenge. We present a case report of a 59-year-old female Hispanic patient who initially presented with melanonychia and was eventually diagnosed with subungual melanoma in situ.

Multiple sclerosis with megacystic presentation: A case report.

Multiple sclerosis is a frequent condition where the diagnosis relies on clinical presentation, neurologic examination, cerebro spinal fluid markers, and diagnostic imaging tests; however, atypical variants of the disease can lead to misdiagnosis in some scenarios. Herein, we describe a case of a 24-year-old patient with multiple sclerosis with megacystic plaques, in which appropriate interpretation of the imaging findings lead to a proper diagnosis and treatment.

Spontaneous rupture of chemotherapy catheter diagnosed using chest X-ray oblique projections: An interventional radiology approach.

Totally implanted central venous port systems are widely used to access central veins for patients needing long-term therapy. These devices have low rates of complications and are commonly used to administer medications like chemotherapeutic agents. Spontaneous rupture of a catheter segment is a rare mechanical complication, usually belatedly diagnosed and presenting with complications.

Severe Frostbite Due to Extreme Altitude Climbing in South America: A Case Report.

Frostbite is a tissue injury secondary to freezing that can currently be categorized using two schemes (Cauchy and clinical scheme). However, we present a fourth-degree frostbite case with overlapping features between both classifications, generating difficulty in categorizing it using either. We wanted to raise awareness of such an atypical presentation and propose employing both classifications to define the extent and compromise of frostbite more appropriately.

Clinical and Radiological Characteristics to Differentiate Between EGFR Exon 21 and Exon 19 Mutations in Patients With Lung Adenocarcinoma: A Systematic Literature Review and Meta-Analysis.

Epidermal Growth Factor Receptor (EGFR) mutations in lung adenocarcinoma have been previously associated with specific clinical characteristics and Computed Tomography (CT) patterns. However, associations among individual EGFR mutations have not been evaluated. We aim to differentiate if the most common EGFR mutations (exon 21 and 19) are related to specific clinical characteristics or CT patterns.

Diagnostic approach to Aicardi syndrome: A case report.

Aicardi syndrome is an X-linked-dominant genetic condition that is present almost exclusively in females. To diagnose Aicardi syndrome, the classic triad of agenesis of the corpus callosum, infantile spasms, and chorioretinal lacunae must be present. Here, we described a case of a female newborn baby delivered at 36 weeks of gestation that arrived at the emergency department with stiffening of arms and legs; therefore, an electroencephalogram was performed, showing generalized polypots confirming infantile spasms.

Pleuroperitoneal Hernia in an Adult Patient.

Introduction: Pleuroperitoneal hernia is the most frequent diaphragmatic congenital hernia, appearing in 1 in 3,000 births. This diaphragmatic defect is located on the left side in 80% to 90% of cases. Pleuroperitoneal hernia is usually diagnosed in the first 8 weeks of life due to respiratory compromise caused by the herniation of abdominal organs into the thoracic cavity; therefore, adult presentation is a rare condition.

Computed tomography findings of Crouzon syndrome: A case report.

Crouzon syndrome is a genetic condition characterized by a premature fusion of skull sutures resulting in head and facial deformities. Crouzon syndrome is usually suspected at birth through physical examination or in the antenatal period via ultrasonographic assessment. Once Crouzon syndrome is suspected, advanced imaging methods such as three-dimensional computed tomography must be requested, showing early signs of cranial sutures fusion.

Clinical and CT patterns to predict EGFR mutation in patients with non-small cell lung cancer: A systematic literature review and meta-analysis.

Purpose: This study aims to determine if the presence of specific clinical and computed tomography (CT) patterns are associated with epidermal growth factor receptor (EGFR) mutation in patients with non-small cell lung cancer.

Methods: A systematic literature review and meta-analysis was carried out in 6 databases between January 2002 and July 2021. The relationship between clinical and CT patterns to detect EGFR mutation was measured and pooled using odds ratios (OR).
