Abstract Background Cogan’s anterior internuclear ophthalmoplegia (INO) is characterized by INO with inability to converge and commonly thought to be due to rostral midbrain lesion. A lesion outside midbrain that causes unilateral Cogan’s anterior INO combined with upgaze palsy and ataxia are rarely described. Case presentation A 67-year old male presented with left Cogan’s anterior internuclear ophthalmoplegia (INO), left appendicular ataxia and bilateral upgaze palsy. A Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiography (MRA) brain showed a left dorsal tegmental infarct at the level of pontomesencephalic junction. Conclusions This case highlights the clinical importance of Cogan’s anterior INO in combination with upgaze palsy and ataxia, and report possible site of lesion in patients with such constellation. Clinicians should consider looking for cerebellar signs in cases of Cogan’s anterior INO, apart from just considering localizing the lesion at the midbrain.

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.

AbstractRare case of bilateral internuclear ophthalmoplegia (INO) following head injury in 25-year-old male is being reported. The site of the lesion in the mid-brain as detected in the magnetic resonance imaging (MRI) correlates well with the clinical presentation. The patient recovered on conservative treatment with a course of dexamethasone (for brainstem contusion).

Vulvar Mass

Abstract Background Lipomas are often small tumors and rarely reach a size larger than 2 cm. Vulvar lipoma is a rare tumor localization, and only a few cases have been reported. It is important to distinguish lipomas from other vulvar masses like liposarcomas, Nuck canal cyst, Bartholin’s cyst, and inguinal hernias. Case presentation We report on a case of a 43-year-old woman who presented with a giant left vulvar mass and discuss the magnetic resonance imaging (MRI) results. Conclusions MRI is useful in evaluating vulvar lipomas and differentiating them from other vulvar pathologies.

In this report, we present a rare patient with Wernicke encephalopathy (WE) in whom the initial magnetic resonance imaging (MRI) was normal. However, cranial MRI, performed two weeks later, showed lesions compatible with WE. Via the presentation of this patient, we discuss the need for future studies of larger cases including the temporal evaluation of the MRI characteristics of Wernicke encephalopathy.

Intrathoracic endometriosis is classified into pleurodiaphragmatic endometriosis and bronchopulmonary endometriosis. Bronchopulmonary endometriosis is rare. Computed tomography (CT) findings of bronchopulmonary endometriosis are lung nodules, with or without cavities, or surrounding ground-glass opacities. Features vary with menstrual status. Recently, the usefulness of magnetic resonance imaging (MRI) was reported for diagnosis of intrathoracic endometriosis, but most published reports were about pleurodiaphragmatic endometriosis. We present CT and MRI findings of bronchopulmonary endometriosis in the left lung that showed a gradually enlarging nodule with enhancing area.

Oropharyngeal teratomas are extremely rare congenital tumors and have an incidence rate of one in 35,000-200,000 newborn babies/neonates. Oropharyngeal teratomas may cause life threatening airway obstruction to a newborn. Early diagnosis with ultrasound and magnetic resonance imaging (MRI) is essential to plan management. Here, we present a rare case of oropharyngeal true teratoma diagnosed with MRI antenatally in a fetus at 34 weeks of gestation in a 25-year-old female who was being evaluated for polyhydraminos. We found MRI to be more helpful for antenatal diagnosis, counseling, and management than ultrasonography and computed tomography (CT).

Abstract Medulloblastoma is the most common malignant tumor of childhood. Neuroimaging can play a role in the diagnosis of medulloblastoma, however atypical features do exist [2]. We report the case of a 1 year and 10- month-old infant diagnosed with a medulloblastoma with what we term “excessive” nodularity based on neuroimaging features and confirmed by neuropathology. CT-scan (CT) and magnetic resonance imaging (MRI) examination of the brain revealed a very large posterior fossa tumor attached to tentorium. On T2-weighted and post-gadolinium sequences, the tumor shows an extensive nodular grape-like appearance. Initial the patient was underwent a ventriculo-peritoneal shunt. The second operative procedure was tumour resection. Histology examen revealed a diagnosis of medulloblastoma desmoplastic with extensive nodularity. The neuroradiographic features of this medulloblastoma with what we describe as “excessive” nodularity are important to recognize as these children may be cured with chemotherapy alone.
