Craniopharyngiomas (CPs) are rare benign epithelial tumours. Brain arteriovenous malformations (AVMs) are also rare lesions occurring in young adults. The appearance of both these lesions in the same patient is rare. A 42-year-old patient presented with headaches for 3 months and a progressive decrease in his visual acuity. Bitemporal hemianopsia was detected in the visual field. Magnetic resonance imaging (MRI) revealed a tumour with cystic and solid components located in the suprasellar region and AVM in the right temporal lobe. AVM (Martin–Spetzler grade III) was visualised using digital subtract angiography (DSA), which was fed from the right middle cerebral artery and drained through the sigmoid sinus via the inferior petrosal sinus. The patient was operated with enlarged right frontotemporal craniotomy. AVM nidus was totally removed at the first operation. Embolisation was not preferred before the AVM surgery. After 3 days, sylvian dissection was performed using the same craniotomy. The tumour was completely removed via the carotid cistern by making sharp dissection from the infundibulum. Post-operatively, the patient showed normal neurological examination and significant improvement in his visual field examination. There was no residual/recurrent tumour or AVM on contrast-enhanced MRI and DSA at post-operative 6 months. Histopathological examination revealed AVM in the first operative material and papillary-type CP in the second.  The coexistence of these two rare pathologies has previously been reported in only one patient. This is the first case of surgical resection of CP and AVM using the same craniotomy.

A 30-year-old woman (gravida 0) visited our hospital with a complaint of right lower abdominal pain. Transvaginal ultrasonography revealed a 5-cm swollen right ovary, which was suspected to be a mature cystic teratoma. Pelvic examination revealed moderate pain. Contrast-enhanced computed tomography showed a 44-mm cystic mass containing fat and calcified material in the right pelvis. Since torsion was suspected, emergent laparoscopic surgery was performed. Intraoperative findings were a swollen right ovary without torsion or congestion. Two small pedunculated 1- and 2-cm diameter paratubal cysts that grew from almost the same place of the ampulla of the right fallopian tube were observed. The thin stalk of the 1-cm paratubal cyst was entangled around the stalk of the 2-cm paratubal cyst, with its head congested. Through a small abdominal laparoscopic incision, the tumor of the right ovary and the two paratubal cysts were excised. Histopathological examination revealed that the right ovarian tumor was a mature cystic teratoma, and the two paratubal cysts had no malignancy. This case showed that only a 2-cm tumor with congestion caused the acute abdomen.

Purpose: Demyelinizing neurological disease is a rare complication after treatment with tumor necrosis factor (TNF)α antagonists. We report on a case of multiple sclerosis after TNFα antagonist treatment and discuss its differential diagnosis. Methods: This is an observational case study. Results: A 48-year-old male was referred to Ophthalmology in January 2015 for an absolute scotoma in the superior quadrant of the visual field in his right eye. Visual acuity was 20/50 in the right eye and 20/20 in the left. Fundus examination was unremarkable bilaterally. Spectral domain optical coherence tomography revealed a normal macular retina structure. Visual field examination revealed a superior hemianopsia in the right eye. Head magnetic resonance imaging showed findings compatible with optic neuritis. The visual evoked potentials confirmed the presence of optic neuritis. The patient had been under therapy with adalimumab since January 2014, for Crohn’s disease. Suspension of adalimumab was recommended, and it was substituted with tapered deltacortene, from 1 mg/kg/day. After 1 month, the scotoma was resolved completely. Conclusions: TNFα antagonists can provide benefit to patients with inflammatory autoimmune diseases. However, they can also be associated with severe adverse effects. Therefore, adequate attention should be paid to neurological abnormalities in patients treated with TNFα antagonists.

Abstract Introduction. Leprosy is a disease that predominantly affects the skin and peripheral nerves, resulting in neuropathy and associated long-term consequences, including deformities and disabilities. According to the WHO classification, there are two categories of leprosy, paucibacillary (PB) and multibacillary (MB). The standard treatment for leprosy employs the use of WHO MDT (Multi Drug Treatment) regimen, despite its multiple downsides such as clofazimine-induced pigmentation, dapsone-induced haematological adverse effects, poor compliance due to long therapy duration, drug resistance, and relapse. Multiple studies and case reports using ROM regimen have reported satisfactory results. Nevertheless, there are still insufficient data to elucidate the optimum dosage and duration of ROM regimen as an alternative treatment for leprosy. Previous experience from our institution revealed that ROM regimen given three times weekly resulted in a satisfactory outcome. Case Reports. We report two cases of leprosy treated with ROM regimen from our institution. The first case was PB leprosy in a 64-year-old male who presented with a single scaly plaque with erythematous edge on the right popliteal fossa. Sensibility examination showed hypoesthesia with no peripheral nerve enlargement. Histopathological examination confirmed Borderline Tuberculoid leprosy. ROM regimen was started three times weekly for 6 weeks and the patient showed significant clinical improvement at the end of the treatment with no reaction or relapse until after 6 months after treatment. The second case was MB leprosy in a 24-year-old male patient with clawed hand on the 3rd-5th phalanges of the right hand and a hypoesthetic erythematous plaque on the forehead. Histopathology examination confirmed Borderline leprosy. The patients received ROM therapy 3 times a week with significant clinical improvement after 12 weeks. Conclusion. ROM regimen given three times weekly for 6 weeks in PB leprosy and 12 weeks in MB leprosy resulted in a significant clinical improvement. Thus, ROM regimen could be a more effective, safer, faster alternative treatment for leprosy.

A 4-month-old female mixed breed dog was presented to the University of Tennessee College of Veterinary Medicine with a history of regurgitation and cachexia. Thoracic radiographs revealed focal megaesophagus cranial to the heart base. Magnetic resonance imaging (MRI) was performed. True fast imaging with steady-state precession (TrueFISP), fast low angle shot (FLASH), and short tau inversion recovery (STIR) sequences were acquired prior to contrast medium administration. Contrast-enhanced magnetic resonance angiography (CE-MRA) demonstrated focal megaesophagus and position of the aortic arch to the right of the esophagus. A small ductus diverticulum and an indistinct linear soft tissue band crossing the esophagus were also noted. Surgical exploration confirmed MR diagnosis of a persistent right aortic arch (PRAA) with left ligamentum arteriosum. The dog improved following surgery but was unable to be transitioned to dry food. To our knowledge this is the first report describing the use of CE-MRA for preoperative diagnosis and guided surgical treatment of a vascular ring anomaly in a dog.

Abstract Background: Hepatic mesenchymal hamartoma (HMH) is an uncommon benign tumor in children. While mesenchymal hamartomas may be angiomatous and blood vessels may be identified, HMH with a malignant tumor symptom on the contrast-enhanced hepatic computed tomography angiography (CTA) has not been described. Here, we present the first case of HMH mimicking hepatoblastoma on the hepatic CTA from pathological point of view and review the imaging and histological features of this unique lesion. Case presentation: A 2-year-old female child was found a distention in the right abdomen and was admitted to our hospital. The Hepatic CTA showed that the blood vessels were thickened, the tumor blood vessels were clustered in the tumor. According to the hepatic CT findings, the tumor was considered to be malignant, possibly a hepatoblastoma. Microscopic examination showed a tumor arranged in lobules, composed of loose myxoid mesenchyme surrounding ductal structures, with intervening vascular channels. The Immunohistochemical staining revealed positive CK7 and CD34 for the bile duct elements and the lining endothelial cells of the vascular channels. There were abundant blood vessels around the nodules and the margins of remaining hepatocytes, but few in the central region. The blood vessels are small, thin-walled vessels and presented like capillaries and venules. Conclusions: A histological diagnosis of Hepatic Mesenchymal Hamartoma was confirmed by the microscopic examinations. This case adds learning points to radiologists when heterogeneous reinforcement on enhanced CT scan was presented in such a large childhood liver tumor.

Trabecular Carcinoma

A 68-year-old woman with solid/trabecular follicular thyroid carcinoma inside of an autonomously functioning thyroid nodule is described in this paper. The patient was referred to our clinic for swelling of the neck and an increased pulse rate. Ultrasonography showed a slightly hypoechoic nodule in the right lobe of the thyroid. Despite suppressed TSH levels, the -pertechnetate scan showed a hot area corresponding to the nodule with a suppressed uptake in the remaining thyroid tissue. Histopathological examination of the nodule revealed a solid/trabecular follicular thyroid carcinoma. To the best of our knowledge, this is the first case of hyperfunctioning follicular solid/trabecular carcinoma reported in the literature. Even if a hyperfunctioning thyroid carcinoma is an extremely rare malignancy, careful management is recommended so that a malignancy will not be overlooked in the hot thyroid nodules.

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.

Spontaneous pneumothorax is rarely reported in the cat. This case report describes the use of computed tomography (CT) to diagnose pulmonary bullae in an adult cat with recurrent spontaneous pneumothorax. A large bulla in the right middle lung lobe and several blebs in other lobes were identified by CT. Partial lobectomy of the right middle and right and left cranial lung lobes was successfully performed to remove the affected portions of lung. Histopathological examination suggested bronchopulmonary dysplasia (BPD) as the underlying cause for development of the pulmonary bulla. This is the first case report in the veterinary literature describing the use of CT to identify pulmonary bullae in the cat with BPD as a possible underlying cause.

Abstract A case of a giant aneurysm arising from the anterior cerebral artery and producing a left homonymous hemianopsia is presented. The aneurysm caused lateral compression of the posterior part of the optic chiasm. After preoperative dynamic assessment of the circle of Willis by angiography and by electroencephalographic recording during carotid artery compression, the aneurysm was trapped with microclips on the anterior cerebral artery proximal and distal to it. Visual field examination 6 months postoperatively showed complete visual field recovery. This is the first case of homonymous hemianopsia caused by an angiographically proven giant aneurysm of the ACA. (Neurosurgery 22:560-563, 1988)

Purpose To present a case with co-existence of Cogan-Reese syndrome and exfoliation syndrome. Case report A 72-year-old Caucasian woman presented for consultation due to uncontrolled intraocular pressure (IOP) of the right eye. Clinical examination revealed the presence of Cogan-Reese syndrome and exfoliation syndrome OD. This eye exhibited elevated IOP, open anterior chamber angle, advanced glaucomatous optic nerve head damage, and severe glaucomatous visual field loss. The left eye was completely normal without IOP elevation or visual field damage. To our knowledge this is the first case report demonstrating the coexistence of the Cogan-Reese syndrome, exfoliation syndrome, and secondary open-angle glaucoma. Since both syndromes frequently lead to secondary open-angle glaucoma, it is not feasible to determine with certainty which condition was the cause of secondary open-angle glaucoma in our case. It is conceivable that both conditions contributed to glaucoma development. Conclusions Cogan-Reese syndrome, exfoliation syndrome and secondary open-angle glaucoma may present on the same eye.
