RESUMEN
Right-sided aortic arch, first documented by Fioratti and Aglietti in 1763, is a rare variant of the thoracic vascular anatomy present in about 0.1% of the adult population. In half of these cases the left subclavian artery is also aberrant. The aberrant left subclavian artery usually originates from a conical dilatation near its origin from the aorta also known as "Kommerell's diverticulum." Fewer than 80 of these cases have been reported in the literature as far as our web search is concerned. It is usually asymptomatic and diagnosed incidentally during adulthood. We are presenting a 56 years old male patient presented with right side chest and shoulder pain of 1 week duration. The pain exacerbated with motion of the right upper extremity and radiates to his lower back. However, he had no history of cough, shortness of breath, syncope, and dysphagia. The vital signs were in normal range. Pulmonary and cardiovascular exam were unremarkable. The complete blood count (CBC), electrocardiogram (EKG), and echocardiography showed no abnormality. In the adult population a right-sided aortic arch with an aberrant left subclavian artery arising from Kommerell's diverticulum is a rare occurrence often asymptomatic unless aneurysmal disease or compression of mediastinal structures ensues. Even though it is rare and at times an incidental finding, the condition is clinically relevant because of the morbidity caused by the complications. We report a case of Kommerell's Diverticulum of an aberrant left subclavian artery in an adult patient with a right-sided aortic arch. Right-sided aortic arch with aberrant left subclavian artery arising from Kommerell's Diverticulum is quite rare and may remain asymptomatic. On times it may cause symptoms in adulthood often as a result of early atherosclerotic changes of the anomalous vessels, dissection, or aneurysmal dilatation with compression of adjacent structures causing dysphagia, dyspnea, cough, or chest pain. Even though there are no general guidelines for the management of this condition patients need to be informed about the nature and possible outcomes of their condition. Close follow up of asymptomatic patients is one option of management until there are situations which require consideration of surgical intervention.
RESUMEN
Esophageal cancer (EC) is among the top ten worldwide causes of cancer related morbidity and mortality. Squamous cell carcinoma (SCC) accounts for over 90% of all cases in sub-Saharan Africa [1]. Azygos arch and azygos vein tumor thrombus in esophageal squamous cell carcinoma (ESCC) is a rarely reported phenomenon. We report a case of tumor thrombus in the azygos vein and arch in a patient with esophageal squamous cell carcinoma. To date only a single case of such tumor thrombus in the arch of the azygos vein have been reported which was subsequently managed with neoadjuvant chemotherapy followed by radical resection [2].
RESUMEN
Pulmonary arteriovenous malformation is characterized by an anatomic right-to-left shunt between the pulmonary arteries and veins, is characterized by an anatomic right-to-left shunt which reduces the arterial oxygen saturation and then results in clinical manifestations such as dyspnea and cyanosis. Most cases are congenital, and although uncommon, they are a significant part of the differential diagnosis of pulmonary problems like hypoxemia and lung nodules. We present a case of a 60 years old female patient who presented with the complaint of exacerbation of dry cough of 1-month duration and was diagnosed with right pulmonary arteriovenous malformation and successfully treated with surgery.
RESUMEN
Intra-cardiac retained bullets rare entities in clinical practice owing to the high mortality associated with it. We present a case of a 26-year-old male patient presented 24 days after sustaining a bullet injury to the left side of the chest. Intra-operatively totally myocardial bullet was found within the right ventricle and extracted successfully.
RESUMEN
Stump appendicitis is a rare complication of appendectomy because of recurrent inflammation of the residual appendix. The diagnosis is often delayed because of low index of suspicious, which may result in serious complications. Twenty-three-year-old male patient presented with right lower quadrant abdominal pain after 7 month of appendectomy done at a hospital. On physical examination, he has right lower quadrant tenderness and rebound tenderness. Abdominal ultrasound was done with finding of blind-ended tubular noncompressible 2 cm long part of appendix with wall-to-wall diameter of 10 mm. There is also focal defect with surrounding fluid collection. With this finding, perforated stump appendicitis was diagnosed. He was operated with similar intra operative finding. The patient discharged improved after 5 days of hospital. This is first reported case in Ethiopia as far as our search is concerned. Despite past medical history of appendectomy, the diagnosis was made by means of ultrasound scan. Stump appendicitis is a rare but important complication of appendectomy, often misdiagnosed. Prompt recognition is important to avoid serious complications. This pathologic entity should always be kept in mind in case of right lower quadrant pain in patient with previous history of appendectomy.
