Adult giant hydronephrosis is a rare clinical entity. His clinical diagnosis is not obvious. We report a case of a 42-year-old man, who was admitted for a large intra-abdominal mass, painless, evolving for about 8 months. The clinical examination showed a very distended abdomen. The abdominal CT confirms the diagnosis of left giant hydronephrosis on ureteral lithiasis. Surgical treatment consisted of an emergency percutaneous nephrostomy followed by a secondary left nephrectomy. The evolution was favourable and the aftermath were simple.

Manubriosternal joint (MSJ) dislocation is often poorly tolerated, with pain, and both static and dynamic dysfunction in breathing. This injury is rare, and treatment includes both surgical and non-surgical interventions. Moreover, the treatment needs to be personalised to a specific case. We present a case of a 19-year-old Comorian man who had chest pains that were exacerbated by movements after falling from a tree. Careful physical examination revealed that the man had a 'stair step'-looking deformity located at the anterior chest wall at the level of the MSJ. A computed tomography scan confirmed the diagnosis of manubriosternal disruption. The patient underwent a surgical intervention under general anaesthesia and had an uneventful recovery.

Background: Pheochromocytoma (PH) is a rare tumor developed at the expense of the adrenal medulla and secreting catecholamines. It is also a rare cause of curable hypertension in adults. Case information: We reported a case of PH in a 39-year-old Malagasy woman, with no particular history. The clinic was dominated by the onset of paroxysmal hypertension associated with headache, palpitations, and sweating. Its clinical manifestations were revealed by the insertion of an etonogestrel contraceptive implant. Despite the removal of the contraceptive implant and the taking of an antihypertensive drug based on a calcium channel blocker, the hypertension persisted with a paroxysmal character and always associated with the Menard triad. Results: The diagnosis was made against the elevation of urinary metanephrines and normetanephrines and the presence of a heterogeneous left adrenal mass on computed tomography. Surgical resection of the tumor made it possible to perform an immunohistochemical examination confirming the diagnosis. Without surgical complications, the patient's blood pressure as well as urinary metanephrine and normetanephrine, normalized without taking any antihypertensive drug. Conclusion: Hormonal contraception could be wrongly blamed the cause of hypertension. Then she would just be a triggering factor. Thus, any atypical hypertension following the use of a hormonal contraceptive must encourage the search for a secondary cause such as PH.
