The Epstein-Barr virus (also known as EBV), responsible for infectious mononucleosis, is a virus that infects the majority of the world's population. Infection occurs in several forms, most often asymptomatic, or as a fever accompanied by pharyngitis and lymphadenopathies. A rare complication of infectious mononucleosis is acute acalculous cholecystitis, an inflammation of the gallbladder characterized by ischaemia and severe cholestasis. The diagnosis of this pathology is made by imaging, but determining the cause may be tricky. We present here the case of acute acalculous cholecystitis in a 21-year-old woman. This case highlights a rare complication of EBV infection that is probably under-diagnosed, and demonstrates the usefulness of interpreting liver tests and leukocyte count in association with imaging findings.

Central venous access is common practice in intensive care, anesthesia and emergency departments. It is, however, a delicate technical procedure, prone to complications. We present a case report on the placement of a left jugular central venous line in the emergency room, which was thought to be a routine procedure. However, the operator observed arterial blood during sampling, and the central line was described as poorly positioned on the control X-ray. After verification and other examinations, the existence of a vertical vein was discovered in this patient, connecting the left superior pulmonary vein to the brachiocephalic trunk. A poorly positioned central venous line can therefore lead to the discovery of asympomatic congenital vascular anomalies, unrelated to the clinical context. This case study illustrates the various tools available to ensure the correct position of a central venous line, and their clinical implications.

RHOBTB2 was first described as epileptogenic when it presents a missense variant in 2016 and studied more specifically in 2018. It is a gene that causes rare, but potentially severe childhood epileptic encephalopathy. In 2021, research confirmed that heterozygous mutations of RHOBTB2 included other clinical signs besides these encephalopathies. Thus, these infantile epilepsies are mainly associated with highly variable phenotypes, with developmental delay, post-traumatic encephalitis, paroxysmal movement disorders and iconographic brain damage. In this work, after presenting a clinical case, we will recall the role of RhoGTPases on neuronal development. We will then discuss a study which highlighted the neurodevelopmental impact of mutations on the RHOBTB2 gene by carrying out work on Drosophila melanogaster flies. Finally, we will compare the presented clinical case with a literature review.

Duodenal ulcer perforation in patients undergoing gastric bypass surgery is a rare late complication, occurring in less than 1% of cases. It carries a high mortality risk, particularly in cases of delayed diagnosis. The challenge lies in an unspecific clinical presentation and laboratory findings, as well as a CT scan not very helpful in almost half of cases. These features may lead to the consideration of other differential diagnoses, such as pancreatitis or cholecystitis. A multidisciplinary approach in collaboration with digestive surgeons is essential to enable rapid exploratory laparoscopy in presence of diagnostic uncertainty, and appropriate therapeutic management.

Grisel's syndrome is a non-traumatic atlantoaxial (C1-C2) subluxation and one of the causes of torticollis in children. The subluxation occurs in the context of an infection in the ENT ("Ear Nose and Throat") region or following surgery. Diagnosis is based on clinical examination and radiological assessment. Treatment is typically medical and conservative, with surgical interventions reserved for recurrences and late presentations. We discuss here two cases of C1-C2 subluxation. The first case involves a 10-year-old child with subluxation following a rhinopharyngitis. This presentation is the classical manifestation of Grisel's syndrome. Prompt management led to correction of the subluxation using medical treatment and a soft Philadelphia collar. The second case involves a 34-year-old adult who developed posterior headaches after sphenoidotomy surgery. Grisel's syndrome is less common in adults, leading to clinical challenges and delayed diagnosis (> 1 month). Reduction combined with a halo vest treatment failed, and the patient required cervical arthrodesis.

A pericardial cyst is a rare and benign lesion, most commonly of congenital origin. A female patient of 35 years old was admitted to the emergency department of our institution, for non-irradiating thoracic pain associated with a dyspnea. A CT-Scan was performed, and a pericardial cyst of a large size was found. A surgical procedure through thoracoscopy was performed to enhance the symptomatology of the patient and to eradicate the cyst. The diagnosis of these lesions is most commonly sporadic after a radiography performed for other causes. Most of the time these lesions are asymptomatic (although thoracic pains, chronic cough and dyspnea amongst others may be observed). In case of suspicion (related to radiography or an eventual symptomatology) a thoracic scan is performed with a contrasting product for the confirmation and localization of the cyst. In addition to the diagnosis and the localization, it is best to perform a transthoracic ultrasound which enables a differential diagnosis with other lesions (lipoma, aortic aneurysm, solid tumour, and a left ventricle aneurysm etc.). A surgical treatment is recommended in symptomatic cases. In non-symptomatic cases, a transthoracic ultrasound is recommended.

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis. Half of the cases are associated with an immune dysfunction and are frequently triggered by pathergy such as a tissular aggression via surgery or burn wounds. A patient with ulcerative colitis presented a PG at the site of an iontophoresis patch for tendinopathy. Treatment in a specialized burn center, corticosteroid therapy and adapted local care contributed to a favourable evolution. PG remains a diagnosis of exclusion and inflammatory phenomena must be differentiated from infectious causes such as necrotizing fasciitis to initiate immunosuppressive treatment. Being rare and difficult to diagnose and to treat as well as associated with potentially severe sequelae, a multidisciplinary team is required for the management of PG.

Background: Cesarean scar pregnancy is a complicated and potentially life-threatening type of ectopic pregnancy. There is no gold standard for its management. The aim is to demonstrate the efficacy and safety of treatment by hysteroscopic tissue removal system after systemic methotrexate injection.

Methods: We report the case of a 27-year-old patient who had previously had a C-section and who presented herself to the emergency room with pelvic pain and metrorrhagia. The human chorionic gonadotrophin (hCG) serum level was positive. The exploration revealed an ectopic pregnancy on the cesarean scar. She benefited of 4 systemic injections of methotrexate. As the hCG became negative, endovaginal ultrasound confirmed the avascular nature of the mass. Surgical resection by mechanical morcellation hysteroscopy (TruClear™) was performed under general anaesthesia, visual control and ultrasound guidance.

Results: This procedure was successful. It was an ambulatory procedure and there were neither intra- nor postoperative complications.

Conclusions: To our knowledge, this is the first time in Belgium that a hysteroscopic tissue removal system procedure has been used to treat a caesarean scar pregnancy. This technique seems to be safe for both the patient and the surgeon and could become a new approach for cesarean scar pregnancy management.

Superior vena cava syndrome (SVCS) is a clinical picture resulting from the obstruction of superior vena cava. SVCS usually causes symptoms and signs related to the head, the neck, the upper extremities and the upper thorax. We report a case of unusual clinical presentation of SVCS in a 25-year-old male patient who suffered from lymphoblastic lymphoma in childhood. Clinicians should be aware of abdominal wall presentations of SVCS especially in patients having undergone central venous catheterization, even years before. SVCS could be an emergency situation, requiring specific treatment or contraindicating surgical procedures.

Bone tumors are and remain rare entities in our daily hospital clinical practice. Their appearance seems anecdotal but does not remain absent. They can manifest directly (pain, redness, functional impotence, suspicious mass, etc.) or indirectly (inflammatory or paraneoplastic syndrome, profuse sweating, emaciation, etc.). The most common benign bone tumors are non-ossifying bone fibroma. Then come osteochondroma and solitary bone cysts. For malignant tumors, osteosarcomas and chondrosarcomas are at the forefront. Primary bone lymphoma accounts for less than 1 % of these. In general, lymphomatous bone lesions are frequently metastasis from primary hematological lymphoma and are therefore treated by chemotherapy. An early surgical treatment of the bone tumor is most often not mandatory and a conservative therapy may represent a valuable option.
