Here, we report a case of an infectious pseudoaneurysm at the root of the innominate artery, compressing the trachea, that resulted in massive hemorrhage due to rupture of the innominate artery. The patient, a 31-year-old man, had complained of persistent fever for 40 days and severe dyspnea for 1 week. Contrast-enhanced computed tomography imaging of neck and thorax showed a pseudoaneurysm originating from the root of the innominate artery that was severely compressing the main trachea. A hybrid surgery strategy was applied. We first implanted a covered stent in the root of the innominate artery. Then, we performed a left-to-right carotid−carotid bypass with a great saphenous vein graft. Finally, we performed a median thoracotomy in which both the pseudoaneurysm and the previously implanted covered stent were successfully extracted. The patient lost strength in the right upper limb muscle on postoperative day 2 but recovered to baseline strength after 3 months. A hybrid surgical technique may represent a practical solution for such conditions.

Abstract Primary angiosarcoma is extremely rare malignant tumor that has no typical symptoms and progress rapidly with poor prognosis. It is mesenchymal in origin and observed most frequently in the right atrium, cases in the pericardium is much more rare. Only few can detected in the early-stage allowing complete radical resection with a mean survival of 3 months to 1 year. There is few pericardial angiosarcoma reported among these years. The present study reports a case of a 44-year-old woman with primary pericardial angiosarcoma, who underwent a wide range of imaging methods, including transthoracic echocardiography, contrast-enhanced computed tomography (CT) and positron emission tomography-magnetic resonance imaging (PET-MRI). The patient recovered well after operation in two years and died due to the recrudescence and pulmonary metastases in April, 2020. We report the case for its rarity and revealing the early detection of primary pericardial angiosarcoma with imaging examinations is critical for prognosis. Finally a literature review is done.

Introduction: Renal trauma is a relevant cause of morbidity in children older than 1 year. Most patients are currently managed conservatively, even in case of high-grade traumas; nevertheless, harmful complications may occur even in hemodynamically stable patients. We present a case of grade IV blunt renal trauma complicated by post-traumatic pseudoaneurysm. Case description: A 10-year-old girl was referred to our institution for grade IV trauma of the right kidney. During observation she had persistent hematuria that caused anemia. A second contrast-enhanced computed tomography scan revealed a posttraumatic pseudoaneurysm that was successfully treated by angiographic embolization. Conclusions: Although extremely rare after blunt renal trauma, post-traumatic renal pseudoaneurysm may cause severe blood loss and anemia, and angioembolization is therefore indicated. This condition should be suspected and move physicians to investigate further.

A 77-year-old man, who was on anticoagulation, presented with a painful lump on the right abdominal wall. Laboratory tests showed slight anaemia and elevated inflammatory markers. Abdominal plain computed tomography (CT) revealed a mass in the right rectus abdominis muscle. He was admitted with a diagnosis of primary rectus abdominis haematoma. However, on the next day, the diagnosis was corrected to primary rectus abdominis abscess, following contrast-enhanced CT of the abdomen. This case illustrates the importance of considering primary rectus abdominis abscess in patients with suspected primary rectus abdominis haematoma, and contrast should be used when performing CT.

Primary squamous cell carcinoma (SCC) of the renal parenchyma is a very unusual entity which needs to be differentiated from primary SCC of renal pelvis, SCC from another primary site, and urothelial carcinoma with extensive squamous differentiation. We are most probably describing the second case of primary SCC of the renal parenchyma in a 51-year-old male who presented with heaviness of right upper abdomen with intermittent pain in right flank. Contrast-enhanced computed tomography (CECT) revealed a mass in the right lower pole of the kidney and histopathology following nephrectomy displayed the features of well-differentiated squamous cell carcinoma without urothelial involvement.

Renal infarction is a rare clinical entity that is not easily detected by low-sensitivity ultrasound. We herein report a case of dermatomyositis with renal infarction detected during corticosteroid therapy. The patient was followed up for 18 months. A woman who was clinically diagnosed with dermatomyositis complained of severe pain in the right flank of the low back and abdomen, accompanied by nausea and vomiting during corticosteroid therapy. Based on the findings of routine blood tests, abdominal X-ray radiography, and abdominal ultrasound, the patient was diagnosed with acute gastroenteritis and treated with levofloxacin. However, her symptoms were not relieved. Abdominal contrast-enhanced computed tomography revealed renal infarction. Clinicians should be alert to the occurrence of thrombosis, especially when it manifests as vasculitis in patients with rheumatic disease who complain of severe abdominal pain, because it may suggest the presence of renal infarction.

Background: Endometriosis mainly affects female pelvic tissues and organs, and the presence of endometriosis in the kidney is extremely rare.Case Presentation: We report a case of a 48-year-old woman who presented with intermittent hematuria. She was found to have a cystic mass on renal ultrasonography, and contrast-enhanced computed tomography (CT) showed slight enhancement of the cystic wall and septa. These findings were indicative of cystic renal tumor. The patient subsequently underwent partial right nephrectomy. Histopathology revealed endometriosis of the right renal parenchyma. The patient recovered well and had no evidence of a recurrent renal mass at the 3 months' follow up.Conclusion: The possibility of renal endometriosis should be considered in a female patient with a cystic renal mass and clinical symptoms related to the menstrual cycle.

<p>Giant tonsillolith is a rare clinical entity. We present the case of a 7 years old male who presented with sore throat and difficulty in swallowing. Right tonsil was bulging into the oropharynx with marked peritonsillar swelling and inflammation and a provisional diagnosis of peritonsillar abscess was made. Contrast enhanced computed tomography scan revealed a large-sized tonsillolith on the right side. The patient underwent elective stone removal and tonsillectomy.</p>
