Abstract We report the case of a patient with successful total removal of a previously undescribed intracranial tumor arising in the right lateral ventricle (probably of metaplastic origin). The histopathological examination revealed benign chondromatosis of the choroid plexus. The pathogenesis of this lesion, with special reference to synovial chondromatosis and to the differential diagnosis of solid neoplastic chondromas, their clinical features, and computed tomographic and magnetic resonance imaging findings, is presented and discussed.

Plexus Papilloma

Abstract The authors report the successful total removal of a rare intracranial tumor in the right lateral ventricle of a 15-year-old girl with epileptic seizures. Histopathological examination showed a benign tumor formed by mature cartilage and choroid plexus papilloma. From our review of the literature, a mixed tumor with these histological features has not been reported previously in this location. The diagnosis, surgical approach, etiology, and prognosis of this lesion are discussed.

Actinomycosis is an infrequent infectious disease caused by Actinomyces species. Actinomycoses in the nasopharynx are extremely rare, especially in the Rosenmüller’s fossa. This report presents a case of actinomycosis in the Rosenmüller’s fossa. A 75-year-old woman presented with a 6-month history of bloody sputum. A grayish-white caseous tissue was found in the right Rosenmüller’s fossa after retracting the torus tubarius. Magnetic resonance imaging showed a well-defined lesion with low-signal intensity on T1- and T2-weighted images; small low-signal areas were interspersed inside. The lesion was removed under an endoscope. Histopathological examination revealed eosinophilic, club-shaped structures surrounding a hematoxylophilic center, leading to the diagnosis of actinomycosis. The symptoms improved after 3 months of amoxicillin administration but recurred quickly. After 6 months of amoxicillin administration, the bloody sputum disappeared, and local and imaging findings were normal.

Microsurgical Procedure

Objective: The authors report a case of femoral nerve schwannoma by MR imaging findings. Case: A patient presenting with right inguinofemoral pain and swelling was submitted to a Gadolinium-enhanced Magnetic Resonance Imaging (MRI): a schwannoma arising from the femoral nerve in the right inguinofemoral area was disclosed. She  underwent microsurgical procedure, with total removal of the lesion. Postoperatively, the inguinofemoral pain and swelling disappeared, with complete relief of symptoms. Conclusion: The authors stress that femoral nerve schwannoma in the inguinofemoral place should be considered according to MRI findings.

SummaryA nine-year-old male castrated European Shorthair cat was presented with a six-day history of progressive depression and ataxic gait. Neurological examination revealed depression, absent menace in the left eye, absent pupillary light reflex in the right eye, anisocoria, circling to the right, and delayed proprioception in all limbs. Magnetic resonance imaging showed a space-occupying right temporal lobe lesion adjacent to a small defect in the temporal bone suggestive of a meningo-encephalitis with concurrent abscess formation. The site was surgically approached by a rostrotentorial craniectomy. A cerebral abscess was found and debrided. Histopathological examination of the removed tissue demonstrated a subacute to chronic purulent encephalitis with extensive necrosis of brain tissue. Neurological symptoms resolved completely within two weeks and full recovery was observed four weeks after surgery.

Possible Cause

Abstract We report the case of a 61-year-old man in whom numbness developed on the right side of the penis, scrotum, and perineum after he jumped into a swimming pool. Magnetic resonance imaging and a computed tomographic scan disclosed a lesion at S1-S2 impinging on the right S2 nerve root. At surgery, ruptured disc material originating in an area normally occupied by the fixed fibrocartilaginous plate was identified and excised. Postoperatively, the numbness resolved. We discuss a possible cause of the rupturing of the sacral disc and recommended treatment by laminectomy and excision, as in other cases of ruptured disc at other levels of the spinal column.

Abstract We report a case of cerebellar schwannoma in a 64-year-old woman. The tumor was defined on computed tomographic and magnetic resonance imaging scans and confirmed on surgery. The solid part of the tumor appeared to be derived from the inferior vermis of the cerebellum, the cystic part extending toward the medulla oblongata and the foramen magnum. The problem of preoperative diagnosis based on magnetic resonance imaging findings is discussed.

Lymphoepithelial cyst (LEC) is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature. We report a rare case of LEC in the palatine tonsil.
