The clinical and pathologic features of 43 dogs with neoplasia of the rostral cerebrum were reviewed. Primary brain tumors included meningioma, astrocytoma, neuroblastoma, oligodendroglioma, and ependymoma. Other tumors that secondarily affected these areas included solitary hemangiosarcoma, nasal neuroendocrine carcinoma, nasal cell adenocarcinoma, nasal squamous cell carcinoma, and nasal neurofibrosarcoma. Older dogs were usually affected (mean, 10 years), and meningioma was the most frequent tumor type. Thirty-one dogs (72% of total) had a late-onset (greater than 5 years of age) of either generalized seizures or behavior abnormalities, or both, with an initially normal neurologic examination. In these 31 dogs, a mean time of 78 days (range, 2 to 400 days) elapsed from the onset of seizures or behavior change to the detection of a persistently abnormal neurologic examination. In all 43 dogs, the time from the detection of neurologic deficits to death or euthanasia and necropsy ranged from 1 to 63 days (mean, 13 days). On the basis of this review, it appears that dogs with late-onset seizures or behavior change, or both, should be suspected of having tumors involving the rostral cerebrum, despite the absence of persistent neurologic deficits commonly associated with cerebral tumors. Further, the onset of abnormalities in the neurologic examination and the time of death seem to occur within predictable time periods.

The characterisation of adrenal lesions is a common radiological dilemma. Incidental adrenal lesions are commonly detected with computed tomography (CT), and lesion characterisation is critical. The prevalence of incidental adrenal lesions has been reported to be 2.3% at autopsy and 0.5-2% with abdominal CT. Such lesions are likely to be seen with increasing frequency given the expanding use of radiological imaging in clinical practice. Although the majority of adrenal lesions are benign, in patients with an extra-adrenal primary cancer the probability of an adrenal mass being a metastasis is 52%. Unfortunately, there may be significant overlap between the imaging appearances of benign lesions such as lipid-poor adenomas and malignant lesions, particularly metastases and small adrenal carcinomas. This review highlights recent advances in radiological imaging of adrenal lesions and we discuss the relative merits of CT and magnetic resonance imaging to aid the identification of benign and malignant adrenal lesions and their roles, in combination with biochemical and clinical data, in recognizing common pathologies such as adrenal adenoma, phaeochromocytoma, carcinoma and metastases. We also discuss the radiological characteristics of rarer adrenal lesions including lymphoma, neuroblastic tumours (neuroblastoma, ganglioneuroblastoma, and ganglioneuroma), lipomatous tumours (myelolipoma, angiolipoma, teratoma, lipoma and liposarcoma), in addition to hemangioma, hemangiosarcoma and leiomyosarcoma.
