Project description:Middle meningeal arteriovenous fistula (MMAVF) is a shunt between the middle meningeal artery and the vein surrounding the artery. We report an extremely rare case of spontaneous MMAVF; then, we evaluated the effectiveness of trans-arterial embolization for spontaneous MMAVF and the possible cause of spontaneous MMAVF. A 42-year-old man with tinnitus, a left temporal headache, and pain surrounding the left mandibular joint was diagnosed with MMAVF on digital subtraction angiography. Trans-arterial embolization with detachable coils was conducted, which resulted in a fistula closure and symptoms' diminishment. The cause of MMAVF was thought to be the rupture of the middle meningeal artery aneurysm. A middle meningeal artery aneurysm can be a cause of spontaneous MMAVF, and trans-arterial embolization might be an optimal treatment.

Project description:Ureteral trauma is a rare case and generally results from severe trauma events. A 6-year-old boy came with the chief complaint open wound in the lower right abdomen after falling from the bike. Abdominal MSCT with contrast showed the free liquid in the peritoneal cavity, and Retrograde Pyelogram showed the contrast extravasation. According to the algorithm, a surgical exploration must be performed because of the contrast extravasation. In this case, there found a total rupture of right distal ureter. Debridement was performed, and Double J Stent was implanted. This patient got treatment quickly so he didn't suffer disability and death.

Project description:BackgroundVideo-assisted thoracoscopic surgery (VATS) has been widely performed for patients with lung cancer. Splenic rupture after VATS lung procedures is a very rare and serious event.Case presentationWe reported a case with hemodynamic instability after left lower VATS lobectomy. There was no evidence of diaphragmatic injury during the surgery. Computed tomography (CT) showed spleen injury and large amount of fluid in the abdominal cavity. Emergent laparotomy was performed, and splenic rupture was diagnosed. The patient underwent splenectomy, with two lacerations at the diaphragmatic surface of the spleen. The patient did well postoperatively and was discharged from the hospital on postoperative day 5.ConclusionThere are few similar cases reported in the literature. Persistent hemodynamic instability due to the rupture of spleen is life-threatening. In the situation of unexplained hypotension during VATS procedures (especially left-sided approaches), the possibility of splenic injury and rupture should be considered. Abdominal ultrasonography and/or CT examinations should be carried out for prompt diagnosis and treatment of such rare complication.

Project description:ABSTRACT Pheochromocytoma presents various clinical manifestations and imprecise signs and symptoms. Along with other diseases, it is considered to be ‘the great mimic’. This is the case of a 61-year-old man who on arrival presented with extreme chest pain accompanied by palpitations, and with a blood pressure of 91/65 mmHg. An echocardiogram showed an ST-segment elevation in the anterior leads. The cardiac troponin was 1.62 ng/ml, 50 times the upper limit of normal. Bedside, echocardiography revealed global hypokinesia of the left ventricle, with an ejection fraction of 37%. Because ST-segment elevation myocardial infarction-complicated cardiogenic shock was suspected, an emergency coronary angiography was performed. It showed no significant coronary artery stenosis, while left ventriculography demonstrated left ventricular hypokinesia. Sixteen days after admission, the patient suddenly presented with palpitations, headache and hypertension. A contrast-enhanced abdominal CT showed a mass in the left adrenal area. Pheochromocytoma-induced takotsubo cardiomyopathy was suspected.

Project description:BackgroundSplenic rupture associated with trauma is common within the population, however, spontaneous splenic rupture is noted to be a rarity in clinical practice. Spontaneous splenic rupture is usually associated with hematologic, neoplastic, or infectious disorders, with infectious mononucleosis associated with Epstein-Barr virus being the most common cause worldwide. Spontaneous splenic rupture without underlying cause is thought to be exceedingly rare. In this article we present a case involving a true spontaneous splenic rupture.Case descriptionWe present the case of a 73-year-old female with past medical history significant for hypothyroidism, hypertension, squamous cell carcinoma of the chest, and history of tobacco use who presented to the emergency department with acute onset of left-sided flank pain radiating to her shoulder beginning three days prior. Computed tomography of the abdomen and pelvis without contrast revealed an acute splenic injury concerning for rupture with contour obscured by blood products with associated mild to moderate hemoperitoneum. The decision was made to proceed with emergent exploratory laparotomy and splenectomy. Patient received her post splenectomy vaccinations. On follow-up appointment, patient was noted to be doing well.ConclusionsThis case highlights the importance of early diagnosis and treatment of atraumatic splenic rupture, as delayed diagnosis and treatment is associated with significant morbidity and mortality. Operative intervention including splenectomy remains the mainstay of treatment, in addition to appropriate resuscitation. Some authors have reported cases in which hemodynamically stable patients are able to be treated non-operatively, however, the long-term consequences are unknown. Atraumatic spontaneous splenic rupture is often low on the differential diagnoses due to its rarity. Unfortunately, it carries a high risk of morbidity and mortality, and thus timely diagnosis and intervention is imperative.

Project description:IntroductionAcute blunt traumatic diaphragmatic rupture (BTDR) caused by falling from a height is rare. Transabdominal diaphragmatic repair in an acute setting following BTDR requires good clinical decision-making and diagnostic tests.Case presentationA 36-year-old male was involved in a work accident. He fell from a 30-m radio transmitter tower while wearing an attached safety body harness. He arrived in the emergency room with complaints of breathing difficulty, abdominal and pelvic pain. We discovered a diaphragmatic rupture with abdominal organ herniation based on the imaging. We decided to perform an emergency laparotomy. We discovered a 12cm diaphragmatic defect on the anteromedial side of the left during surgery. We carried out the evacuation by suction and controlled the bleeding in the wound at the edge of the diaphragm. On postoperative day 4 (POD), the patient complained of dyspnea, and chest radiology revealed a hemothorax in the left lung. We then installed a water-sealed drainage (WSD) until POD 6. On the following day, his complaint was resolved, the WSD was removed and the patient was discharged uneventfully.DiscussionAbdominal CT scan can be helpful in determining early diagnosis of traumatic diaphragm rupture with abdominal organ herniation, allowing for prompt surgical intervention to minimize morbidity and mortality. Furthermore, reinforced sutures might be useful to prevent recurrence of the symptoms.ConclusionIn conclusion, injury due to wearing a safety body harness when falling can be a potential cause of BTDR. Management of BTDR transabdominally is a safe and effective procedure.

Project description:BackgroundPheochromocytomas (PHEOs) are a group of tumours that leads to multiple symptoms and can induce hypercoagulability and promote thrombosis. Pheochromocytomas may also present without elevated serum and urinary markers. We aimed to provide tips and tricks for the diagnostic and therapeutic management of an unusual case of PHEOs.Case summaryThirty-four-year-old woman with the unremarkable medical history presented with epigastric pain and dyspnoea. Electrocardiogram showed ST-segment elevation in the inferior limb leads. She underwent an emergency coronary angiogram, which showed a high thrombus burden in the distal right coronary artery. A subsequent echocardiogram demonstrated a 31 × 33 mm right atrial mass adhering to the inferior vena cava and abdominal computed tomography (CT) scan revealed a 113 × 85 mm necrotic mass in the left adrenal bed, with tumour thrombus extending proximally to the confluence of hepatic veins immediately inferior to the right atrium and distally to iliac vein bifurcation. Blood parameters, thrombophilia panel, vanillylmandelic acid, 5 hydroxy indole acetic acid, and homovanillic acid levels were normal. Tissue sampling confirmed the diagnosis of PHEOs. The surgical procedure was not planned due to the presence of metastatic foci on imaging, including positron emission tomography (PET)-CT. Anticoagulation with rivaroxaban and treatment with 177Lu-DOTATATE-based peptide receptor radionuclide therapy (PRRT) was initiated.DiscussionThe coexistence of arterial and venous thrombosis is extremely rare in patients with PHEOs. Multidisciplinary approaches are required for the care of such patients. Catecholamines likely contributed to the development of thrombosis in our patient. Early recognition of PHEOs is the key point to ameliorate clinical outcomes.

Project description:BackgroundAdrenal hemangioma is a rare benign adrenal tumor that is usually misdiagnosed preoperatively. We here present a case of adrenal cavernous hemangioma that was successfully treated with retroperitoneal laparoscopic adrenalectomy.Case presentationA 67-year-old man with dull right back pain attended our clinic for examination of a mass on the right adrenal gland for 1 week. Pheochromocytoma was considered according to the preoperative computed tomography angiography + computed tomography urography findings and was subsequently corrected to adrenal gland hemangioma according to postoperative pathological findings. The patient showed no recurrence of adrenal hemangioma during the 1-year follow-up period after surgery.ConclusionAdrenal gland hemangioma is rare with a high rate of misdiagnosis, and it should be considered in imaging findings of adrenal tumors with typical hemangioma. Surgery is an effective treatment method.

Project description:IntroductionPheochromocytomas combined with aortic dissections are rare. Treatment of aortic dissection can be complicated by the presence of pheochromocytomas.Case presentationwe present the case of a 48-year-old male who visited the hospital with chest and back pain for 13 h. Enhanced computed tomography (CT) revealed a type B aortic dissection combined with a left adrenal mass (72 mm). Elevated 24-h urinary vanillylmandelic acid levels can aid in the diagnosis of pheochromocytomas. Aortic dissection due to unstable hypertension secondary to pheochromocytoma is rare and complicates the procedure. Thoracic endovascular aortic repair was performed, and antihypertensive treatments were administered after surgery. After hypertension was addressed and the patient was stable, laparoscopic resection of the adrenal mass was performed.Conclusionsdespite its rarity, it is important to consider pheochromocytoma as a differential factor for unstable hypertension when an aortic dissection is found.
