We report a case of coincident craniopharyngioma with an unruptured aneurysm at the right M1- M2 segment of the middle cerebral artery; and discuss the surgical approach to two different pathologies treated at same surgical time, as well as current theories to explain the coincidence or association between tumor and vascular lesions at the sellar and suprasellar regions. The patient was a 59-year-old woman; with a history of visual impairment and headache. Both lesions were identified by magnetic resonance imaging (MRI) and cerebral angiography, and were treated surgically. We suggest individualized treatment for each case, choosing the best neurosurgical approach to achieve an appropriate treatment of both pathologies in the same operative session.

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.

Subdural osteomas are extremely rare benign neoplasms. Here, we report the case of a 35-year-old female patient with a right frontal and parietal subdural osteoma. The patient presented with a 2-year history of intermittent headache and fatigue. Computerized tomography (CT) scan showed a high-density lesion attached to the inner surface of the right frontal and parietal skull. Magnetic resonance imaging (MRI) demonstrated T1 hyperintensity and T2 hypointensity of the lesion. Intraoperatively, the hard mass was located in subdural space and attached to the dura mater. Histopathological examination revealed lamellated bony trabeculae lined by osteoblasts and the intertrabecular marrow spaces occupied by adipose tissue. The patient underwent neurosurgical resection and recovered without complication. Surgical excision is recommended to extract the symptomatic lesions with overlying dura mater.

Introduction Paratesticular lesions are common, and one subgroup is paratesticular rhabdomyosarcoma. The latter is a relatively uncommon (but aggressive) tumour that affects children and adolescents predominantly. Ultrasound is the first-line investigation, but can be inconclusive. Magnetic resonance imaging (MRI) can provide useful information, but its role in the diagnosis of rhabdomyosarcoma is not clear. Case History We report a 17-year-old male who presented with a one-month history of a rapidly enlarging, non-tender, lump in the right testicle. Urgent ultrasound of the scrotum revealed a heterogenous paratesticular mass that was hypervascular and showed calcification in the right inguinal area. MRI of the pelvis showed a solid, enhancing lesion of dimension located superior to the upper pole of the right testes and a slightly heterogeneous T2 signal, but was homogenous post-contrast. The patient underwent right radical orchidectomy, and histology results were assessed. He received chemotherapy and is being followed up. Conclusions Improvements in imaging in addition to early surgical intervention and chemotherapy treatment are crucial to improve survival chances against rhabdomyosarcoma. Ultrasound findings for benign diseases may mimic those seen in rhabdomyosarcoma. In such cases of diagnostic uncertainty, our surgical team suggest MRI to reduce the risk of a delayed diagnosis and time to treatment.

A 33-year-old male patient experienced temporary sensory loss and weakness in the right lower extremity one month prior to admission. The patient was admitted to a private clinic with a three-day history of acute onset of sensory loss and weakness in both lower extremities and was treated and followed up with a prediagnosis of transverse myelitis and the Guillain-Barre syndrome (GBS). The patient was subsequently transferred to our clinic and the neurologic examination revealed paraplegia in both lower extremities, positive bilateral Babinski signs, and hypesthesia below the T10 dermatome with saddle anesthesia. The patient had urinary incontinence and thoracic magnetic resonance imaging (MRI) showed an image of a mass compressing the medulla.

Ventilation And Perfusion

Objective: Inhalation of e-cigarettes aerosols (vaping) has the potential to disrupt pulmonary gas exchange, but the effects in asymptomatic users are unknown. We assessed ventilation-perfusion (V̇A/Q̇) mismatch in asymptomatic e-cigarette users, using magnetic resonance imaging (MRI). We hypothesized that vaping induces V̇A/Q̇ mismatch through alterations in both ventilation and perfusion distributions. Methods: Nine young, asymptomatic Vapers with a >1yr vaping history, and no history of cardiopulmonary disease, were imaged supine using proton MRI, to assess the right lung at baseline and immediately after vaping. Seven young Controls were imaged at baseline only. Relative dispersion (SD/Mean) was used to quantify the heterogeneity of the individual ventilation and perfusion distributions. V̇A/Q̇ mismatch was quantified using the second moments of the ventilation and perfusion vs. V̇A/Q̇ ratio distributions, log scale, LogSDV̇ and LogSDQ̇ respectively, analogous to the multiple inert gas elimination technique. Results: Spirometry was normal in both groups. Ventilation heterogeneity was similar between groups at baseline (Vapers: 0.43±0.13, Controls: 0.51±0.11, P=0.13) but increased after vaping (to 0.57±0.17, P=0.03). Perfusion heterogeneity was greater (P=0.04) in Vapers at baseline (0.53±0.06) compared to Controls (0.44±0.10) but decreased after vaping (to 0.42±0.07, P=0.005). Vapers had greater (P=0.01) V̇A/Q̇ mismatch at baseline compared to Controls (LogSDQ̇ = 0.61±0.12 vs. 0.43±0.12), which was increased after vaping (LogSDQ̇ = 0.73±0.16, P=0.03). Conclusion: V̇A/Q̇ mismatch is greater in Vapers and worsens after vaping. This suggests subclinical alterations in lung function not detected by spirometry.

Endocarditis due to melioidosis is rare. A 60-year-old male was admitted with upper abdominal pain and vomiting for one month. Contrast enhancing computed tomography (CT) of the abdomen showed multiple hepatic, splenic and pancreatic nonenhancing cystic lesions. Culture of CT guided aspirate from the liver lesion showed growth of <em>Burkholderia pseudomallei</em>. He was started on ceftazidime and cotrimoxazole. Four days after admission patient developed decreased speech and response. Magnetic resonance imaging (MRI) and MR angioram brain showed massive infarct in the middle cerebral artery territory and occlusion of the middle cerebral artery. Echocardiogram showed vegetation in the aortic valve. He was diagnosed to have disseminated melioidosis with endocarditis resulting in massive infarct in the middle cerebral artery territory.

Safe Approach

Microvascular decompression (MVD) is an effective and safe approach for treating hemifacial spasm (HFS). Postoperative complications may include facial nerve palsy, hearing loss, intracerebral haematoma, and brainstem infarction. The occurrence of intracranial cyst following MVD is extremely rare, with few cases documented in the literature. Herein, the cases of two patients with HFS who developed ipsilateral cerebellar cyst following MVD are reported. The first patient was a 50-year-old male presenting with a 6-year history of HFS on the right side of his face. MVD was performed, and 12 days postoperatively he developed dizziness and nausea. Magnetic resonance imaging (MRI) showed a cyst in the ipsilateral cerebellum. Antibiotic treatment provided no benefit, and the cyst was drained. The second patient was a 44-year-old female presenting with a 4-year history of HFS on the right side of her face. MVD was performed, and 18 days following surgery, she developed dizziness and nausea. MRI showed an ipsilateral cerebellar cyst. Conservative treatment was applied and the cyst shrunk. At the 2-month follow-up appointment, symptoms were completely resolved in both patients. Cerebellar cyst is a rare complication following MVD. Timely diagnosis and appropriate treatment should be emphasized, and surgical treatment may be unnecessary.

Multiple Cranial Neuropathy

We present a case of a 56-year-old man with a history of episcleritis (left) and cluster headache (left) who had a penetrating trauma of the left eye leading to amaurosis 1 month previously. Since then, he developed multiple cranial neuropathy of the right side (V, VII, VIII, IX, X, XI and XII cranial pairs). Magnetic resonance imaging (MRI) revealed an infiltrative lesion of the base of the skull which extended to the retropharyngeal and jugular space, which progressed to multiple leptomeningeal masses extending to the clivus, despite aggressive immunosuppression. Rebiopsy of 1 meningeal mass supported the diagnosis of neurosarcoidosis. The patient finally responded to high-dose prolonged infliximab therapy, with complete remission.
