A 6-year-old spayed female American Cocker Spaniel presented with episcleritis in the right and then the left eye (OS) at eight month interval. Repeated intralesional triamcinolone acetonide was administered subconjunctivally to both eyes (OU). During this period, scleral ectasia was revealed on ocular funduscopy OS and then confirmed on ultrasonography and computed tomography. A year later, conjunctival hyperemia occurred around remnant triamcinolone particles and was treated by resection of these particles in the OU. A recurrence of episcleritis, which did not regress, required repeated triamcinolone subconjunctival injections four months later in the OU. Four months after these injections OU, the dog was presented with bilateral conjunctival mass, which had developed over the previous month. The round-shaped masses with diameters of 1 cm were surgically resected from exposed scleral ectasia lesion of thin and bulging scleral surface in the OU. The cross-section of both masses showed a white-colored accumulation at the center and triamcinolone induced granulomas enclosing necrotic tissue were confirmed by impression cytology and histopathological examination.

A case of idiopathic hypertrophic cranial pachymeningitis (IHCP) misdiagnosed as an acute subdural hematoma is reported. A 37-year-old male patient presented with headache following head trauma 2 weeks earlier. Computerized tomography showed a diffuse high-density lesion along the left tentorium and falx cerebri. Initial chest X-rays revealed a small mass in the right upper lobe with right lower pleural thickening, which suggested lung cancer, such as an adenoma or mediastinal metastasis. During conservative treatment under the diagnosis of a subdural hematoma, left cranial nerve palsies were developed (3rd and 6th), followed by scleritis and uveitis involving both eyes. Magnetic resonance imaging (MRI) revealed an unusual tentorium-falx enhancement on gadolinium-enhanced T1-weighted images. Non-specific chronic inflammation of the pachymeninges was noticed on histopathologic examination following an open biopsy. Systemic steroid treatment was initiated, resulting in dramatic improvement of symptoms. A follow-up brain MRI showed total resolution of the lesion 2 months after steroid treatment. IHCP should be included in the differential diagnosis of subtentorial-enhancing lesions.
