Beyond pulmonary embolism: Alternative diagnosis and incidental findings on CT pulmonary angiography in sickle cell disease.

Background: Sickle cell disease (SCD) is a genetic hematological disorder associated with severe complications, such as vaso-occlusive crises, acute chest syndrome (ACS), and an increased risk of thromboembolic events, including pulmonary embolism (PE). The diagnosis of PE in SCD patients presents challenges due to the overlapping symptoms with other pulmonary conditions. Our previous study revealed that nearly 96% of computed tomography pulmonary angiography (CTPA) scans in SCD patients were negative for PE, highlighting a gap in understanding the significance of CTPA findings when PE is absent.

Warfarin Woes: A Rare Case of Hemoperitoneum with Intramural Small Bowel Hematoma.

BACKGROUND Small bowel hematoma is a rare yet clinically significant condition characterized by the accumulation of blood within the mucosa and submucosa layers of the small intestine wall. It can lead to complications such as bowel obstruction, ischemia, perforation, and even hemorrhagic shock. The etiology of intramural small bowel hematoma is diverse, encompassing factors such as anticoagulant therapy, coagulopathies, vascular disorders, trauma, and underlying systemic conditions.

Frontal Meningoencephalocele With Cerebrospinal Fluid Rhinorrhea: A Case Report.

Traumatic brain injuries are a significant public health concern often associated with immediate consequences. However, delayed complications can manifest, including rare congenital neural tube defects such as encephaloceles. We present a case of a 45-year-old male with a history of traumatic brain injuries who developed a posttraumatic frontal meningoencephalocele associated with cerebrospinal fluid rhinorrhea.

Metastasis of Clear Cell Renal Cell Carcinoma to the Parotid Gland: A Case Report.

Parotid gland metastases from distant primary malignancies are uncommon and present diagnostic challenges for clinicians. We present the case of a 65-year-old male with a history of clear cell subtype of renal cell carcinoma who presented with a painless swelling in the right parotid region. His medical history was significant for a right-sided renal cell carcinoma, for which he had undergone a radical nephrectomy five years ago.

Assessing the Diagnostic Performance of CT in Suspected Urinary Stones: A Retrospective Analysis.

Background Urinary stone disease is a common reason for emergency department (ED) visits, and a computed tomography scan of the kidneys, ureters, and bladder (CT-KUB) is frequently used for diagnosis. The objective of this study was to estimate the positive rate of CT-KUB and identify predictors of emergency interventions for patients with ureteric stones. Methods A retrospective study was conducted to investigate the positive rate of CT-KUB for urinary stone disease and to explore the factors that determine the need for emergency urologic interventions.

Giant Colloid Cyst: A Rare Etiology for Chronic Headache.

Chronic headache affects a significant proportion of the population and can be caused by an underlying lesion or a serious condition. This case report describes a 38-year-old male with a history of chronic migraine headaches who presented with syncope. The patient was found to have bilateral papilledema on fundoscopic examination and a well-circumscribed, oval-shaped lesion located within the intraventricular septum on MRI.

Tracheal Stent Migration in a Patient With Tracheomalacia and Tracheoesophageal Fistula: A Rare Case.

Tracheomalacia refers to diffuse or segmental tracheal weakness. Most commonly, tracheomalacia develops after prolonged endotracheal intubation or tracheostomy. Surgical management is warranted in symptomatic patients with severe tracheomalacia.

Thrombosis of Abdominal Aorta and Bilateral Renal Arteries: Endovascular Treatment in Takayasu Disease.

Takayasu arteritis is an idiopathic vasculitis that typically involves the aorta and its major branches. It is more common in women and has the highest prevalence in Asia. Imaging studies are crucial for establishing the diagnosis and for determining the extent of the disease.

Pulmonary Embolism in COVID-19 Patients: A Retrospective Case-Control Study.

Background: Coagulopathy is a well-recognized complication in patients with coronavirus disease 2019 (COVID-19). Pulmonary embolism (PE) has substantial morbidity and mortality if the diagnosis is missed or the management is delayed. Computed tomography pulmonary angiography (CT-PA) is the imaging modality of choice for PE.
