Magnetic resonance imaging of cerebellopontine angle lesions

Background: Cerebellopontine angle (CPA) tumors are usually benign, and they are divided into extra-axial, intra-axial, extradural, and petrous axis tumors. CPA pathologies can be asymptomatic or it may present with vertigo, tinnitus, or unilateral hearing loss depending upon the site of tumor origin and displacement of the neurovascular structure. Aim and Objectives: To evaluate the role of magnetic resonance imaging (MRI) aided with contrast-enhanced MRI as an imaging modality for diagnosis of CPA lesions. Materials and Methods: Analysis of 36 patients of CPA lesions over a period of 2 years was done. MRI was performed on Siemens 1.5 Tesla MAGNETOM Avanto Machine. Conclusion: There are spectrums of pathologies, which can present with these symptoms, which includes tumors, vascular malformations, and vascular loop compressing vestibulocochlear nerve or mastoid pathology so it is important to investigate the patient by MRI. Contrast-enhanced MRI is the most sensitive investigation in the evaluation of the CPA lesions, its characteristic, and its extent

Morel-Lavallée lesion

Morel-Lavallée lesion is a degloving injury occurring at the interface of the subcutaneous fat and the underlying fascia. The lesion usually results from shearing forces due to trauma separating the skin and subcutaneous tissue. We report here a case of a patient diagnosed with Morel-Lavallée lesion in the hip region

Chronic subdural hematoma-unsual cause of headache in a patient with chronic myeloid leukemia treated with high-dose imatinib mesylate: A rare case report with review of literature

Head injury is considered one of the single most important causes of subdural hematoma. Other cause include bleeding diasthesis. We report here a case of 70-year-old female patient with chronic myeloid leukemia (CML) presenting with bilateral chronic subdural hematoma after an incremental high-dose of imatinib mesylate (IM) due to loss of complete molecular response. IM is useful to treat a wide range of diseases, including Philadelphia chromosome-positive CML, as it has high tolerability and low incidence of minor side effects. Hemorrhage is a rare complication of IM. IM is associated with reduced α2-plasmin inhibitor and platelet dysfunction. This case report emphasizes on the need to consider chronic subdural hematoma as atypical cause of headache in a patient of CML taking high-dose IM

Early diagnosis of slipped capital femoral epiphysis on magnetic resonance imaging: A case report with review of literature

Slipped capital femoral epiphysis (SCFE) is a common hip condition occurring in adolescents, with a prevalence of 10 cases per 100,000 children. It usually affects younger age group from 10 to 17 years. The condition is usually found to be coexistent with various other conditions such as obesity, growth surges, and endocrine disorders such as hypothyroidism, growth hormone supplementation, hypogonadism, and pan-hypopituitarism. Patients present with limping and a poorly localized pain in the hip, groin, thigh, or knee. Diagnosis of the condition is often delayed due to its nonassociation with trauma and hence increases the chances of developing various complications such as avascular necrosis, chondrolysis and deformity. Majority of researches of SCFE are from Europe and North America, while studies in Asian populations are rare. Delay in diagnosis of SCFE is usually due to patients presenting with knee pain. Imaging can thus aid in early diagnosis and appropriate treatment of the disease, which in turn reduces incidence of deformity and disability in the affected children. Bilateral hip radiography - anteroposterior and frog′s-leg lateral views and magnetic resonance imaging (MRI) are the radiological techniques that help in early diagnosis. MRI detects early physeal changes of both preslip and SCFE even when radiographs and computed tomography are normal. MRI should be routinely used to diagnose early SCFE in preslip stage to avoid further complications

Quadrigeminal cistern lipoma: A rare case report with review of literature

Two cases, one of a 6-old-year male and another of 18-year-old female with an intracranial lipoma of quadrigeminal region is reported. Intracranial lipomas usually occur in midline areas and are extremely uncommon with an incidence of 0.1% of all intracranial tumors. These were incidentally detected by computed tomography (CT) or by autopsy. Autopsy incidence of intracranial lipoma is 0.08-0.46%, while incidence of CT findings is not >0.03-0.06%. CT and magnetic resonance imaging (MRI) examination usually lead to the diagnosis, because of the very low attenuation values of lipomas on CT and the short T1 and T2 on magnetic resonance. We describe the findings of imaging studies, including CT, MRI along with a brief review of the literature
