HighlightsMalignant peripheral nerve sheath tumors are highly aggressive soft tissue sarcomas with poor prognosis.The recurrence rate is high.Complete surgical resection is the mainstay of therapy, when possible.

Background: Tympanic paragangliomas are common middle ear benign neoplasias that develop from endocrines cells situated along the great blood vessels of the head and neck, as well as those of the thoracic and lumbar spine. Primary symptoms of tympanic locations include hearing loss and pulsatile tinnitus. Otoscopy often shows a retrotympanic reddish mass, causing tympanic bulging. Computerized tomography scan findings include a tissue density regular mass located at the promontory and limited within the middle ear cavity. Surgical management comprises tumour excision with control of bleeding, with or without prior embolization. Aim: The aim of this presentation is to report an unusual case of tympanic paraganglioma. Case Presentation: We report the case of a 56-year-old patient whose clinical and paraclinical presentations were consistent with cholesteatoma, though a tympanic paraganglioma was discovered per-operatively. Conclusion: In some rare cases, tympanic paraganglioma can be present like a cholesteatoma.

Decompression illness is a rare complication of scuba diving. We report the case of a 29-year-old military man who was admitted to Emergency Department of General Hospital Douala a few minutes after a diving exercise, with complete dysphagia, dysphonia, rotatory vertigo, gait and balance disorder, and severe neck pain radiating along the back. After an emergency treatment, check-ups revealed a cerebral-medullary infarction which confirms the diagnosis of severe decompression sickness. In the lack of hyperbaric oxygen, the patient received normobaric oxygen therapy, antiplatelet agent, hyperhydration and physiotherapy. Les accidents de décompression (ADD) sont des complications rares au décours d’une plongée sous-marine. Nous rapportons le cas d’un militaire de 29 ans admis aux urgences de l’Hôpital Général Douala (HGD) quelques minutes après un exercice de plongée et qui a présenté une dysphagie complète, une dysphonie, des vertiges rotatoires, un trouble de la marche et de l’équilibre et des vives douleurs cervicales irradiant le long du dos. Après une prise en charge en urgence des bilans faits ont révélé un infarctus cérébromédullaire qui confirme le diagnostic d’accident de décompression sévère. En l’absence de l’oxygène hyperbare, le patient a été mis sous oxygénothérapie normobare, antiagrégant plaquettaire, hyperhydratation et physiothérapie.
