Isolated Posterior Mediastinal Thyroid Nodule Simulating Esophageal Pathology: A Multi-Modality Diagnosis.

Posterior mediastinal goiter is not a common cause of dysphagia, and symptoms can simulate esophageal malignancy. This case report highlights two critical clinical aspects. First, the patient's symptoms of gradually worsening dysphagia to solids and liquids, odynophagia, and hoarseness of voice secondary to retrosternal thyroid nodule extension can simulate esophageal malignancy. Second, a barium swallow study can effectively rule out esophageal pathology even though more advanced studies, like High-resolution computed tomography (HRCT), are inconclusive. We present a unique case of isolated posterior mediastinal exophytic thyroid nodule simulating the symptoms of esophageal pathology.

Bilateral Cerebral Hemorrhagic Infarctions: An Early Presentation of Carbon Monoxide Poisoning.

Carbon monoxide (CO) poisoning is one of the most common causes of morbidity secondary to accidental or intentional exposure. It is a potentially life-threatening disease. We present the case of a 23-year-old male patient who slept with a gas generator the whole night in a closed room. The next morning the patient presented to emergency with altered mentation. His Glasgow Coma Scale score was 8/15 on arrival. The patient had cerebral hemorrhages on presentation with diffuse cerebral hypoxic injury and bilateral globus pallidus signals. Hemorrhagic infarction in the brain is a rare presentation of CO poisoning and even rarer as an early manifestation of this disease. We present a case of bilateral posterior cerebral hemorrhagic infarctions with a diffuse hypoxic insult as an early presentation of CO poisoning in a young male, which to our knowledge has rarely been reported. Early imaging and prompt medical attention can be life-saving.

Bladder Endometriosis Masquerading as Bladder Tumor: The Role of Magnetic Resonance Imaging in Diagnosis.

Bladder endometriosis is an infrequent cause of a focal bladder mass and may masquerade as a neoplasm on ultrasound imaging. This diagnostic dilemma can be resolved with a multiparametric MRI, which shows characteristic hemorrhagic signals of this entity. We present an unusual case of bladder endometriosis where the patient complained of lower abdominal pain without urinary symptoms and was found to have a bladder mass on ultrasonography. This mass was further investigated by an MRI of the pelvis, which revealed characteristic features of endometriosis; the diagnosis was confirmed on subsequent laparoscopy.
