A paraganglioma is a rare extra-adrenal neuroendocrine tumour with a variable clinical presentation. A paraganglioma can arise anywhere along the sympathetic and parasympathetic chains, but it can occasionally emerge from unusual locations such as the liver and the thoracic cavity. We report a rare case of a woman in her 30s who presented to our emergency department with symptoms of chest discomfort, episodic hypertension, tachycardia and diaphoresis. A diagnostic approach including a chest X-ray, an MRI and a positron emission tomography-CT scan showed a large exophytic liver mass protruding into the thoracic cavity. For further characterisation of the mass, a biopsy of the lesion was performed, demonstrating that the tumour is of neuroendocrine origin. This was supported by a urine metanephrine test showing high levels of catecholamine breakdown products. Treatment consisted of a unique multidisciplinary approach involving hepatobiliary and cardiothoracic surgery allowing a safe and complete extermination of the hepatic tumour and its cardiac extension., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Paraneoplastic syndromes are rare abnormal endocrine or immune responses triggered by neoplasms. Chronic inflammatory demyelinating polyneuropathy (CIDP) is one such example. CIDP is an acquired, immune-mediated neuropathy affecting the peripheral nerves and nerve roots. It is associated with many types of cancers, especially haematological malignancies. We report the case of a man in his 60s who presented to the emergency department with acute symptoms of upper and lower extremity paresis and decreased sensation in the toes and tips of his fingers. Laboratory tests were normal. Electrodiagnostic studies showed diffuse motor and sensory dysfunction in all extremities; a diagnosis of CIDP was consequently made. Imaging studies showed a large left lobe liver mass. Subsequent biopsy revealed histopathological findings characteristic of hepatocellular carcinoma. After failure of medical treatment with intravenous immunoglobulin and corticosteroids, laparoscopic resection of the tumour was planned, performed and resulted in complete resolution of symptoms. At 18 months postoperatively, the patient was asymptomatic., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023. No commercial re-use.

We, here, report the case of a 72-year-old man who presented with a giant sacral chordoma without aggressive clinical and neurological course and confirmed with a CT guided biopsy. The patient underwent multidisciplinary, two-stage successful complete en bloc sacrectomy along with total gross tumour resection, followed by lumboiliac fusion and instrumentation in the second stage without any neurological deficit nor bladder or bowel-related complications., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Spontaneous intraperitoneal haemorrhage can occur in any age group. It is defined as presence of free blood in the peritoneal cavity which can results from a non-traumatic and non-iatrogenic cause. Common causes are visceral, coagulopathy related and vascular. The clinical presentation is usually non-specific; it can vary from mild abdominal pain to a shock status. We report a very rare case of a 17-year-old male patient who presented to our institution with spontaneous intraperitoneal bleeding secondary to avulsion of one of the short gastric artery following forceful retching.

A 75-year-old woman presented with acute onset dyspnoea, and was found to have signs of pulmonary congestion on clinical examination. Imaging revealed cardiomegaly and coincident congestive hepatopathy, secondary to a left renal arteriovenous malformation. The presence of a high flow vascular shunt in the left kidney was possibly the causative factor behind both the high-output cardiac failure and congestive hepatopathy.

Pancreatitis is a known cause of pseudoaneurysms of the peripancreatic arteries, which can rarely rupture into various adjacent structures and become a source of life-threatening bleeding. The management is challenging and requires an individualised approach and multidisciplinary care. Herein, we present the case of a 24-year-old man in whom a splenic pseudoaneurysm ruptured into the adjacent infected pseudocyst, communicating with the colon by a fistulous tract, causing massive lower gastrointestinal bleeding. This was successfully managed by transcatheter arterial embolisation (TAE).
