Leptomeningeal Metastasis Mimicking a Subacute Epidural Hematoma: Case Report.

Leptomeningeal carcinomatosis is extremely rare in colorectal adenocarcinoma, its incidence is far less than 1%. The neurological symptoms are pleomorphic. The most common symptoms included Headache, ataxia, cranial nerve palsies, meningismus, focal weakness or numbness. MRI is the most sensitive and specific imaging method for screening, positive diagnosis and pre-treatment of leptomeningeal carcinomatosis. The presence of appropriate neuroimaging abnormalities in a patient with typical clinical features and history of colorectal adenocarcinoma enables to make the diagnosis of leptomeningeal metastases. As well as a biological confirmation is necessary. Treatment usually comprises site-specific radiation therapy in addition to intrathecal and systemic chemotherapy. The case aims to describe the MRI characteristics of leptomeningeal metastases so as to formulate the diagnosis and the subsequent treatment.

Cutaneous metastasis as a first sign of breast carcinoma.

Unlike visceral, lymphonodal or bone metastases, skin metastases are rare and their identification portends of a bad prognosis. They may appear as the first sign revealing the primary tumour, synchronous or developing late in the course of neglected primary cancer. We report a case of 86 year-old women witch belongs to this rare group of patients in whom cutaneous metastasis were identified before the primary cancer. This case showed the interest of biopsy and imaging in the confirmation of the diagnosis.

Complicated abdominal wall hernia mimicking an abdominal wall abscess: A case report.

Abdominal wall hernias are a common imaging finding. Their most common complications include bowel obstruction, incarceration, strangulation and trauma. We report an exceptional case of spigelian hernia in 55 years old women complicated by perforation and massive subcutaneous emphysema which was correctly diagnosed by CT scan. This case showed the interest of CT scan with multiplanar reconstructions in the confirmation of the diagnosis.

A rare cause of exophthalmia: Osteoblastoma of the frontal sinus.

Osteoblastoma is a rare benign tumor arising predominantly in the vertebrae or long tubular bones. Its naso-sinusian origin is rare and can be responsible for ophthalmological complications [1]. We report the case of 19-yeaold patient admitted to the Ophthalmology department for progressive right exophthalmia and ptosis evolving over 8 months. The diagnosis of osteoblastoma was suspected on CT and MRI imaging and then confirmed by the anatomopatological studies. Total surgical excision was performed. Clinical and radiological evolution has been favorable.
