ABSTRACT

Rosai-Dorfman disease (RDD), also known as sinus histocytosis with massive lymphadenopathy, is a rare idiopathic histioproliferative disease affecting the lymph nodes. Although extranodal involvement has been reported in diverse sites, central nervous system manifestations, particularly in the absence of nodal disease with clinical and radiological findings suggestive of meningioma, are extremely rare. Histopathology and immunohistochemistry are essential for a positive diagnosis. We report a case of RDD in a patient presenting multiple meningeal nodules with a review of the literature and discussion of differential diagnosis.

ABSTRACT

A surgical sponge or cotton swab that is inadvertently left behind in a surgical wound eventually becomes a "textiloma". Such foreign material (also called "gossypiboma") can cause a foreign-body reaction in the surrounding tissue. Textiloma is mostly asymptomatic in chronic cases, but can be confused with other soft-tissue masses. Therefore, it is important to be aware of patients who present with a paraspinal soft-tissue mass and unusual or atypical symptoms. Imaging is helpful for arriving at the correct diagnosis. Here, we describe a case of textiloma in which the patient presented with low-back pain 6 years after laminectomy and lumbar discectomy. Spinal computed tomography (CT) and magnetic resonance imaging (MRI) revealed a mass lesion in the posterior paravertebral region.

ABSTRACT

An acute subdural hematoma is commonly regarded as a complication of a head injury, and bleeding is associated with contusion or laceration of the bridging vein in the subdural space. Occasionally, reports describe non traumatic acute subdural bleeding from the rupture of cerebral aneurysm or vascular malformation. However, acute spontaneous subdural hematomas (ASDH) of arterial origin, without any traumatic history or vascular anomaly, are rarely reported in literature. Here we describe two cases who presented with acute signs of intracranial hypertension secondary to a spontaneous acute subdural hematoma in which spontaneous bleeding from a small cortical artery was seen during operation.

ABSTRACT

Bleeding after surgery for chronic subdural hematoma far from the operative site is a rare phenomenon with possibly serious consequences. We report a case of combined epidural and intracerebral hemorrhage immediately after evacuation of bilateral chronic subdural hematoma. The epidural hematoma was evacuated by emergency craniotomy, but the deep parenchymal hematoma was treated conservatively. The patient recovered progressively with a good outcome. Approximately 30 cases of chronic subdural hematomas complicated by intracerebral hematoma were previously reported, but only seven cases of epidural hematoma. These complications could be avoided if slow, gradual decompression is used during surgery. Clinicians should suspect its occurrence without delay when a postoperative neurological deterioration is demonstrated. Possible mechanisms are discussed.

ABSTRACT

Cystic schwannoma is highly unusual and intraspinal involvement seems to be even more rare. We report a case of intradural lumbar-cystic schwannoma in a 50-year-old man who presented with chronic low-back pain and sciatalgia, which were initially related to a bulging disc. Diagnosis of a tumor origin was suspected two years later on MRI as a hemangioblastoma. The lesion was histologically confirmed to be a schwannoma. Only eight cases of spinal schwannoma with large cyst have been previously reported. Cystic schwannoma should be considered in the differential diagnosis of lumbar intradural-cystic lesion.

ABSTRACT

Paranasal sinus injuries by foreign bodies have a lower incidence compared with facial injuries. Among them, penetrating maxillofacial injuries to the sphenoid sinus and skull base remain rare. We report the case of a 41-year-old man who presented with, after a missile-related maxillofacial injury, a metallic foreign body enclosed within the sphenoid sinus with carotid-canal fracture. Angiographic evaluation showed a mass in the right internal carotid artery. The foreign object was successfully extracted through a transmaxillary sublabial approach with a good outcome. We discuss the extensive preoperative evaluation and interdisciplinary management of this unusual injury.

ABSTRACT

STUDY DESIGN: Case report of a rare form of idiopathic spinal epidural lipomatosis (SEL) manifesting with relapsing and remitting course. OBJECTIVE: To describe this very rare clinical and pathological condition and the results of surgical intervention. SETTING: A department of neurosurgery in Morocco. METHODS: A 24-year-old man presented with a 2-year history of mid-thoracic back pain and progressive neurogenic claudication with two episodes of remitting and relapsing course. Spinal magnetic resonance imaging revealed a fatty epidural mass extending from T4 to T9. Posterior decompression was performed, and he was followed for 3 years after the operation. RESULTS: Pathological examination of the surgical specimen revealed nodules of mature fat cells without neoplasm. The patient's symptoms completely resolved after surgical decompression. CONCLUSION: Fluctuating clinical course has not been reported previously in SEL. Such pathology should be considered in the differential diagnosis of demyelinating diseases.

ABSTRACT

Intraosseous cavernous hemangiomas are a rare finding in the calvarium. It is a benign tumors arising from the intrinsic vasculature of the bone. We report one case observed in a 31 year-old female, presented with a progressive left parietal mass. A plain X-ray of the skull and cranial CT-scan showed a osteolytic lesion in the left parietal bone. Surgery consisted of total resection of the lesion and cranioplasty. The postoperative course was uneventful. Histological study revealed a cavernous hemangioma of the diploe. In view of this observation and the literature review, clinical; radiological and therapeutic aspect of this rare entity are discussed.
