Highlights EPIDEMIOLOGY : paraganglioma of the ZUCKERKANDL organ is a rare neuroendocrine tumour but must be known. DIAGNOSIS : The typical presentation which is the Menard Triad of symptoms, associating headaches, sweating and palpitation. Preoperative diagnosis can be difficult in pauci-symptomatic cases. The Clinical signs, Abdominal-pelvic CT scan and biology are the steps of the preoperative diagnosis. TREATMENT : Treatment is surgical. Preoperative medical preparation is aimed at reducing risks of peroperative hemodynamic instability. The anesthetist should therefore prepare himself to manage blood pressure peaks during the tumour’s dissection, but also the possible low blood pressure at the end of exeresis. Surgery remains the key element of treatment and consists in exeresis of the paragaglioma. PROGNOSIS : paraganglioma of the ZUCKERKANDL organ is often a benign tumor. The resuscitation determines the patient’s prognosis.
Introduction GIST can occur in all segments of the gastrointestinal tract with a predilection for the stomach. Retroperitoneal localization remains exceptional. We report a case to describe our diagnostic and therapeutic approach. Case presentation A 55-year-old patient was admitted with borborygms and a sensation of lumbar swelling for 6 months. He was diabetic and hypertensive. The clinical examination noted a right lumbar mass with perception of bowel sound anterior to the mass, with minimal discomfort and mobility. Ultrasound revealed a hypervascularised, encapsulated, well-limited retroperitoneal tissue mass in contact with the right psoas muscle. Abdomino-pelvic CT scan showed a large, hypervascularized, encapsulated, calcified tissue mass measuring 147 × 106 mm in close contact with the outer edge of the right psoas muscle, suspected of being malignant. MRI noted a suspicious process developed at the expense of the right psoas muscle in its lumbar and iliac portion suggestive of a psoas rhabdomyosarcoma. The patient underwent laparotomy with a retroperitoneal approach by lumbar incision. Histology and immunohistochemistry revealed a GIST expressing CD117. The patient was put on imatinib for 6 months. He is complaint-free after 4 months. Discussion Despite the rarity of retroperitoneal GIST, it should be considered in the presence of any retroperitoneal mass. This will allow for early management. Conclusion Retroperitoneum is an exceptional location for GIST. Surgery remains the mainstay of curative treatment. Adjuvant imatinib reduces the risk of recurrence. The prognosis is usually good.
Highlights Epidemiology: Lipoma of the mesocolon is a rare tumour less described in the literature. Diagnosis: It generally involves large masses. Clinically, it is often asymptomatic. When they exist, these symptoms are less specific and generally due to the large size of the tumour (compression, invagination, hernia). Imaging, especially TDM and MRI are an important step of the preoperative diagnosis. In imaging as in anatomopathology, lipoma-like liposarcoma is the main differential diagnosis. A differential diagnosis with lipoma-like sarcoma must be done. Treatment: Treatment is surgical. However, there are variations in the surgical procedures. Some authors had carried out lumpectomy. In our case, we carried out a left colectomy removing the tumour and the mesocolon, as well as the satellite lymph nodes. Each approach has its arguments, i.e. a conserving treatment exposing to repetition if the histological and/or immunochemistry data come out less reassuring, and a more secure and less invasive treatment. There is no consensus on the procedure which depends on the teams.
Situs inversus is an abnormal placement of the thoracic and/or abdominal organs that are inverted right/left from normal. It is a rare congenital malformation often discovered in childhood. In adults, it can lead to misdiagnosis. Clinical case: A 35-year-old female patient, seen in a hepatogastroenterology consultation for acute spontaneous pain in the right hypochondrium. She had no particular clinical history. A diagnosis of hepatopathy was suspected. Abdominal and pelvic CT scans showed the left liver, stomach and spleen in the right hypochondrium, but with the heart in place, suggesting incomplete situs inversus. The evolution in our patient was spontaneously resolved with analgesics and antispasmodics, which leads us to believe that the volvulus was probably partial and without other complications. Conclusion: In developing countries, antenatal diagnosis of situs inversus is rare and is usually made during a pathology that leads the patient to a medical consultation. CT is one of the key paraclinical examinations for its diagnosis as genetic tests are not widely available.
Background: Acute intestinal ischemia is an abdominal suffering occasioned by a sudden reduction of mesenteric blood circulation. It is a rare and potentially serious medical-surgical emergency, deadly in 50% to 100% of cases. Diagnosis is known to be difficult at the early stage during which a well-conducted treatment may help reduce mortality. Multi-detector scanners were assessed to be far more sensitive and appropriate for the diagnosis of mesenteric ischemia than angiography. Objective: Study the tomodensitometric aspects of acute intestinal ischemia, and the traps of late diagnosis, in order to optimize the care and improve the prognosis of this disease. Patients and Methods: This is a prospective, longitudinal and descriptive study covering a period of nine (9) months. We have included all cases of acute intestinal ischemia. Results: Twenty (20) cases of acute intestinal ischemia were registered i.e. a frequency of 2.2 cases per month. The average age of the patients was 67.8 years with 0.7 as sex ratio. Abdominal pain was noted in all cases. History of cardiovascular disease was found in seven (7) cases. Abdominal angioscan was performed in fifteen (15) cases. There was a suspected diagnosis upon request in ten (10) cases. The main intestinal lesions were the lack of parietal enhancement (13 cases) and parietal thickening (12 cases). There were sixteen (16) cases of acute mesenteric ischemia and four (4) cases of ischemic colitis. The acute mesenteric ischemia was arterial in twelve (12) cases, venous in two (2) cases and mixed in two (2) cases. Diagnosis was made at the stage of intestinal infarction in eleven (11) cases. Ten (10) patients were operated and 10 others were treated medically. Thirteen (13) cases of death were registered. Conclusion: Acute intestinal ischemia is a rare but serious disease.
Objectives To study pulmonary embolism during COVID-19 pneumonia. Patients and Methods This was a one-year retrospective and descriptive study of all patients from three imaging sites with SARS-CoV2 infection. Results Two hundred and thirty-nine patients were included. The prevalence of pulmonary embolism was 18.4%. The average age was 55 years old. The sex ratio was 1.65. Dyspnea (58.6%), cough (56.1%), and chest pain (40.2%) were the most common reasons for consultation. In 151 patients (63.2%), chest computed tomography (CT) angiography was performed without checking level of D-dimer. The level of D-dimers was elevated in 47.8%. Grade 5 of CO-RADS accounted for 62.3%. In 70.5% of cases, the pulmonary embolism was bilateral with subsegmental involvement in 47.7%. Condensation in ‘ground glass’ with ‘crazy paving’ were the predominant typical parenchymal lesions with a frequency of 93.7% and 59.4%. In univariate analysis, D-dimers were significantly associated with the occurrence of pulmonary embolism (p < 0.001). Male sex was associated with a non-significantly higher Risk of having a pulmonary embolism (1.18 95% CI: 0.61–2.31, p = 0.622). The critical level increased the risk of pulmonary embolism in a non-significant way. Only the high level of D-dimers was and this, in a significant way. Conclusion Pulmonary embolism was increased in the context of SARS-CoV2. The chest CT-angiography associated with the dosage of D-dimers constitutes a good diagnostic arsenal.
