Central Skull Base Osteomyelitis: Diagnostic Dilemmas and Management Issues.

The aim of this study is to describe the clinical presentation of central skull base osteomyelitis and to discuss the classical imaging findings and various diagnostic and therapeutic challenges faced in the management of this condition. This is a retrospective analysis of inpatient case records, carried out in a multidisciplinary tertiary care hospital. The study subjects included five elderly diabetic patients presenting to the ENT surgeon or neurologist with headache followed by multiple cranial nerve paralysis with no temporal bone involvement in four patients and a past history of otitis externa in one patient.

Peptide Receptor Radionuclide Therapy (PRRT) of Medullary and Nonmedullary Thyroid Cancer Using Radiolabeled Somatostatin Analogues.

As therapeutic options in advanced medullary and non-iodine avid differentiated (nonmedullary) thyroid cancers are limited and associated with significant toxicity, targeting of somatostatin receptors (SSTRs) for internal radiation therapy provides a promising option. Theranostics (therapy and diagnosis) using radiolabeled somatostatin analogues has proved to be a milestone in the management of SSTR-expressing tumors. Peptide receptor radionuclide therapy using (177)Lu-labeled or (90)Y-labeled somatostatin analogues may have a significant role in the management of medullary and nonmedullary thyroid cancers in those patients where PET/CT with (68)Ga-labeled somatostatin analogues demonstrates significant SSTR expression.
