Spontaneous external jugular vein pseudoaneurysm: A rare cause of neck swelling.

Pseudoaneurysm of the external jugular vein is a relatively unusual cause of a neck mass caused by the low pressure venous system. Regardless of etiology, spontaneous pseudoaneurysms are extremely rare, and only few cases have been described in literature. They require surgery; however, most patients can be safely discharged with close follow-up with a vascular surgeon. This case demonstrates a 30-year-old man who presented with a non-tender, compressible, left-sided neck mass that enlarged with Valsalva, and intermittent paresthesias. Ultrasound confirmed a cystic mass of unknown etiology containing doppler flow suggesting the diagnosis of an external jugular vein pseudoaneurysm, confirmed by a CT angiogrphy. The patient refused the surgery, and we agreed he was safe for discharge at that time and could follow up with vascular surgery as an outpatient.

Successful preoperative embolization of a cystic-solid variant of cerebellopontine angle hemangioblastoma.

Tumors of the cerebellopontine angle (CPA) represent an heterogeneous group which can arise extradural, intradural-extraaxial or intraaxial compartment. Hemangioblastomas of the cerebellopontine angle (CPA) are extremely rare. Computed tomography (CT) and magnetic resonance imaging (MRI) are often the gold-standard radiological imaging modalities used in characterizing the lesion's features, and its relationship with the surrounding structures. They are vascular lesions and may cause profuse bleeding intraoperatively, that is why angiography remains a crucial diagnostic and therapeutic tool, by reducing both the presurgical differential diagnosis, as well as the intraoperative bleeding by providing capability of embolization of this vascular tumor. We present the case of a 65 year old patient with a cystic-solid variety of HMB at the right CPA, which was successfully treated by a combination of an endovascular preoperative embolization and surgery without major complications or neurological deficits.

Embolization for the treatment of renal artery pseudoaneurysm following surgical nephrolithotomy: A case report.

Renal artery pseudoaneurysm is a rare but serious complication following trauma or renal surgery, leading to hematuria and deterioration of renal function. Selective renal artery embolization is an interventional radiologic procedure that can be used to treat these complications. We report a case of a 62 years old woman who developed hematuria following a segmental renal artery pseudoaneurysm after staghorn stones surgical nephrolithotomy, a selective embolization with steel coils was successfully performed.

A tonsillar location of a malignant schwannoma: a case report.

INTRODUCTION: Malignant schwannoma is a malignant tumor of differentiation of Schwann cells or perineural cells. OBSERVATION: The patient was a 74-year-old woman with no particular pathological history. She presented swallowing difficulty of solids and odynophagia, evolving for 1 year. Physical examination revealed a budding tumor of the left palatine tonsil without cervical adenopathy. The CT scan confirmed the lesions and the absence of tumor extensions. Histological and immunohistochemical examination of the biopsy sample of the tonsil tumor concluded to be a malignant schwannoma. The patient underwent a tonsillectomy with postoperative follow-up. DISCUSSION: Malignant schwannomas are aggressive tumors. They usually occur in young adults. They mainly affect nerves and soft tissues. Occurrence in the amygdala is rare. CONCLUSION: The association of malignant schwannoma of the palatine tonsil and advanced age is rare.

[Fistulized thyroid abscess revealing esophageal carcinoma in a young adult]. / Abcès thyroïdien fistulisé révélant un carcinome œsophagien chez un adulte jeunee.

Thyroid abscess is an extremely rare condition. Its diagnosis is often late, which predisposes to serious complications. We report a case of thyroid abscess in a young adult who presented to the emergency room for a basi-cervical swelling associated with dysphonia, dysphagia and dyspnea. Neck ultrasound showed a collection of left thyroid lobe. A cervicothoracic computed tomography objectified an abcess of the left lobe of the thyroid fistulising in the hyoid muscles beneath and left piriform sinus with thickening of the hypopharynx and upper esophageal sphincter. The puncture brought a purulent fluid. Panendoscopy revealed the presence of a tumor proliferation of the upper esophageal sphincter. A biopsy with histological examination concluded to a squamous cell carcinoma. This observation indicates that the thyroid abscess may be the mode of discovery of esophageal cancer. Hence the interest to seek an underlying cause in cases of thyroid abscess.

[Brain tumors in children: about 136 cases]. / Tumeurs cérébrales de l'enfant: à propos de 136 cas.

Brain tumors are the most diagnosed solid tumors in children under the age of 15 years worldwide. However, the epidemiological and anatomopathological profile of these tumors has been poorly described in African and, particularly, in Moroccan literature. This study highlights the epidemiological and anatomopathological peculiarities of primary brain tumors in children living in the region of Marrakech (south Morocco). We conducted a retrospective study in the Division of Anatomic Pathology at the Mohammed VI University Hospital, Marrakech from 2004 to 2016. One hundred and thirty-six patients were diagnosed with primary brain tumor, a mean of 11.33 cases per year. The average age of patients was 8.28 years. Sex-ratio (M/F) was 1.6 with a slight male predominance. Infratentorial tumors were found in 61,53% of cases while supratentorial tumors were found in 38.47% of cases. Infratentorial tumors mainly occurred in the cerebellar hemisphere (61.4%). Eighteen histological types were diagnosed. Astrocytoma and medulloblastoma accounted for 46,32% (29.41% and 16.91%, respectively). In our context, the majority of brain tumors in children was predominant in both age groups: 5-9 years and 10-15 years. The epidemiological data of these tumors from south Morocco are mostly consistent with those already published in North Country's literature and in other non-african countries' literature.
