AbstractOrbital schwannomas are rare, presenting a rate of incidence between 1 and 5% of all orbital lesions. Their most common clinical symptoms are promoted by mass effect, such as orbital pain and proptosis. The best complementary exam is the magnetic resonance imaging (MRI), which shows low signal in T1, high signal in T2, and heterogeneous contrast enhancement. The treatment of choice is surgical, with adjuvant radiotherapy if complete resection is not possible. We report the case of a 24-year-old male patient with orbital pain and proptosis, without previous history of disease. The MRI showed a superior orbital lesion compatible with schwannoma, which was confirmed by biopsy after complete resection using a fronto-orbital approach.

This paper reports an unusual case in which aseptic meningitis presented with sudden sensorineural hearing loss (SSNHL) associated with intralabyrinthine haemorrhage (ILH). A seven-year-old girl presented with sudden right-sided hearing loss with dizziness. She did not have a previous history of bleeding disorders. This child was assessed using audiograms and magnetic resonance imaging (MRI). The patient's hearing loss was irreversible. Steroid therapy was not effective. SSNHL associated with ILH can be one of the negative prognostic factors in children.

Diagnosis Of Bone Metastasis

Sarcomas are rare tumors originating from soft tissue or bone. Diagnosis and treatment of sarcomas should be performed at specialized sarcoma centers, where patients are evaluated at a multidisciplinary tumor conference. We present a case where sarcoma was suspected from magnetic resonance imaging (MRI), but histology revealed a metastasis from thyroid carcinoma, although the patient had no previous history of thyroid malignancy and resection of the thyroid gland was without malignancy. Ultrasound-guided biopsy was possible due to cortical destruction and the multidisciplinary approach with re-evaluation of previous pathology and a thorough patient history enabled a final diagnosis.

Abstract This study aims to report a relatively rare entity—intramedullary tuberculum of cervical spine—and describe its management and some key learning points. Intramedullary tuberculomas are rare entities. Intramedullary tuberculoma is most commonly found in the thoracic cord of a patient and is rarely seen in the cervical cord. We present an intramedullary cervical tuberculoma in a 21-year-old patient with finding of spinal cord compression. All 4 limbs were spastic, with grade 1 power on the right side and grade 3 power on the left side. Sensory deficit was found below the C6 level. Magnetic resonance imaging showed an intramedullary lesion at the C5 to C6 levels. Intramedullary tuberculoma was diagnosed based on clinical symptoms, physical examination, previous history, and magnetic resonance imaging. A C5 to C7 laminectomy was performed. Intramedullary tuberculoma was resected by microsurgery. One year after the surgery, strength returned to normal grade 5. Excellent clinical outcome was obtained with a combination of both medical and surgical treatments. Intramedullary cervical tuberculoma should be removed without delay to eliminate any mass effect on the neurons as soon as possible.

Neurosarcoidosis when encountered by neurologists most commonly presents as cranial neuropathy, peripheral mononeuropathy,polyneuropathy, myopathy, meningitis or myelopathy. There are limited reports in the current literature on the cases of neurosarcoidosis patients presenting with ischaemic stroke. We discuss a 52-year-old patient with a known previous history of cutaneous sarcoidosis presenting with an acute third nerve palsy, facial weakness and ataxia. His magnetic resonance imaging (MRI) brain demonstrated focal signal changes in the midbrain consistent with an acute ischaemic event in the region of his third nucleus, suggesting a partial Claude syndrome presentation. Cerebrospinal fluid (CSF) examination demonstrated an elevated angiotensin-converting enzyme (ACE) level. We discuss the difficulties associated with confirming a diagnosis for his presentation and consider distinctions in stroke in neurosarcoid and its management in comparison to more common causes.

Symptomatic spinal cord metastasis from glioblastoma multiforme (GBM) has rarely been reported in the literature. We report the case of a 27-year-old man that presented with back and bilateral leg pain nine months after the primarydiagnosis of intracranial GBM. A magnetic resonance imaging (MRI) of the lumbar spine showed a L1-L2 tumor that was removed successfully and histopathological examination was consistent with GBM metastasis. Spinal metastasis should be investigated and included in the differential diagnosis if a patient with a previous history of intracranial GBM presentswith spinal symptoms.

AbstractA 37-year-old male patient with Crohn’s disease and multiple liver hemangiomas was referred to our hospital for an atypical hypervascular hepatic lesion detected on an external magnetic resonance imaging (MRI) scan. The patient was otherwise well and had no history of any liver disease. Liver values and tumor markers were normal. Contrast-enhanced ultrasound confirmed multiple hemangiomas in different liver segments and a hypervascular tumor with a hypovascular rim in segment II/IV. Repeat MRI showed a strongly enhancing neoplasm of 2.6 cm with a texture distinctly different from the otherwise relatively uniform hemangiomas, without evidence of interim growth. Ultrasound-guided biopsy revealed a hepatic small vessel neoplasm. Due to the unknown malignant potential, atypical segmental surgical resection was performed. Final histopathological analysis confirmed the complete resection of the lesion. The postoperative course was uneventful.

CONTEXT: Brain metastases are common complications of cancer. Magnetic resonance imaging (MRI), the main diagnostic imaging method in these cases, rarely shows cystic images. CASE REPORT: The patient was a 45-year-old woman who had had severe headache for a month that was refractory to medication, and had previously had breast cancer, which had been treated. The MRI showed the criteria for neurocysticercosis. Since there was no improvement with clinical treatment, we chose to excise the lesions. Histopathological analysis showed an epithelioid malignant neoplasm. CONCLUSION: From immunohistochemical analysis, it was concluded that this was a metastasis of breast carcinoma. Even when the MRI is not characteristic of cerebral metastasis, this hypothesis needs to be ruled out in patients with a previous history of cancer.

Objective: The objective of this study was to outline a novel unique concept of secondary impingement of the muscles, myotendons, and tendons of the rotator cuff from hypertrophy as a result of strength training exercises. Methods: In this retrospective observational study, 58 patients were referred for an magnetic resonance imaging (MRI) by the orthopedic surgeon to the radiology department over a period of 1½ years. All patients gave a history of strength training exercises and presented with clinical features of rotator cuff impingement. Results: We identified features of hypertrophy of rotator cuff muscles, myotendons, and tendons in 12 of these 58 patients. This was the only abnormality on MRI. The hypertrophy of rotator cuff muscles and tendon bulk completely filling the subacromial space to the point of overfilling and resulting in secondary compressive features. Conclusion: Rotator cuff impingement is a common phenomenon that can occur with various inlet and outlet pathological conditions. However, rotator cuff impingement may also result from muscle and tendon hypertrophy from strength training regimens. Hypertrophy of the rotator cuff can result in overfilling of the subacromial space, leading to secondary impingement, which we have termed as “pseudo-impingement.”

Background: Cutis Verticis Gyrata (CVG) is a rare skin disease caused by overgrowth of the scalp, presenting as cerebriform folds and wrinkles. CVG can be classified into two forms: primary (essential and non-essential) and secondary. The primary non-essential form is often associated with neurological and ophthalmological abnormalities, while the primary essential form occurs without associated comorbidities. Discussion: We report on a rare case of primary essential CVG with a 4-year history of normal-colored scalp skin mass in the parietal-occipital region without symptom in a 34-year-old male patient, retrospectively summarizing his pathological and Computer Tomography (CT) and magnetic resonance imaging (MRI) findings. The major clinical observations on the CT and MR sectional images include a thickened dermis and excessive growth of the scalp, forming the characteristic scalp folds. With the help of CT and MRI Three-dimensional (3D) reconstruction techniques, the characteristic skin changes could be displayed intuitively, providing more evidence for a diagnosis of CVG. At the 5-year followup, there were no obvious changes in the lesion. Conclusion: Based on our observations, we propose that not all patients with primary essential CVG need surgical intervention, and continuous clinical observation should be an appropriate therapy for those in stable condition.

History Of Depression

A 27-year-old woman presented to the emergency room after having witnessed generalized tonic clonic seizure while asleep. Birth and development were normal. She had suffered a single febrile seizure at 13 months of age, but had no other seizure risk factors. She was otherwise well except for a history of depression for which she was taking sertraline. Depressive symptoms had been well controlled over the past 3 months, but she had been under increased stress working to finish a doctoral thesis. Neurological examination was normal. Magnetic resonance imaging (MRI) showed modest asymmetry of the hippocampi, slightly smaller on the right, but no abnormal signal and well-preserved laminar anatomy. An electroencephalogram was negative. She was discharged from the emergency room with no treatment. Three weeks later, the patient's boyfriend witnessed an episode of behavioral arrest with lip smacking and swallowing automatisms lasting 45 seconds, after which the patient was confused for 20–30 minutes. The next morning she and her boyfriend kept a previously scheduled appointment with a neurologist.
