Abstract Background Pituitary abscess is a rare condition with nonspecific symptoms that can be delayed. Proper diagnosis needs to occur preoperatively so that the management can be set up accordingly. Accurate diagnosis is challenging because many differential diagnoses can exhibit the same magnetic resonance imaging features. Case presentation We report two cases of pituitary abscess. The first patient was a 66-year-old Arab woman who underwent a surgical procedure for a pituitary macroadenoma and presented 3 months later with chronic headaches and panhypopituitarism. A pituitary abscess was found on the follow-up magnetic resonance imaging. The second patient was a 64-year-old Arab man with no medical history who presented with a chiasmal syndrome with headaches and panhypopituitarism. Brain magnetic resonance imaging showed a heterogeneous pituitary mass that turned out to be a pituitary abscess intraoperatively. These two patients were treated with hormone substitution, endoscopic transsphenoidal drainage, and antibiotherapy, with excellent outcomes. Conclusions Pituitary abscess is a rare and serious condition. Preoperative diagnosis can be challenging because of the many existing differential diagnoses upon imaging. Magnetic resonance imaging is the mainstay technique of imaging due to its multimodal nature. These cases demonstrate the variable patterns of a pituitary abscess seen on magnetic resonance imaging and the potential difficulties in achieving an accurate diagnosis preoperatively due to many other conditions potentially exhibiting the same magnetic resonance imaging features.

Rare Autosomal Dominant Disease

Birt-Hogg-Dubé syndrome (BHD) is a rare autosomal dominant disease characterized by skin fibrofolliculomas, pulmonary cysts, spontaneous pneumothoraces, and renal cancers. Oncocytomas are benign epithelial tumors that are also rare. Recently, there have been a few case reports of BHD with a parotid oncocytoma that appears to have a BHD phenotype. Here we document the eighth known case and describe the magnetic resonance imaging features of the parotid oncocytoma, which mimicked Warthin’s tumor. Radiologists should be aware of the association between these rare disorders.

Primary Cardiac Tumors

The differential diagnosis for a cardiac mass includes primary and metastatic neoplasms. While primary cardiac tumors are rare, metastatic disease to the heart is a common finding in cancer patients. Several “tumor-like” processes can mimic a true cardiac neoplasm with accurate diagnosis critical at guiding appropriate management. We present a pictorial essay of the most common benign cardiac masses and “mass-like” lesions with an emphasis on magnetic resonance imaging features.

Acute Transverse Myelitis

Acute transverse myelitis is a rare and disabling disorder. Data on the imaging features in children are sparse. The aim of this study was to describe the clinical and magnetic resonance imaging findings characteristic of pediatric idiopathic acute transverse myelitis and to identify those with prognostic value. The database of a tertiary pediatric medical center was retrospectively reviewed for patients aged less than 18 years who were diagnosed in 2002-2017 with acute transverse myelitis that was not associated with recurrence of a demyelinating autoimmune event. Data were collected on clinical, laboratory, and imaging findings and outcome. A total of 23 children (11 male, 12 female) met the study criteria. Mean age at disease onset was 10 years, and mean duration of follow-up was 6 years 10 months. Spinal cord and brain magnetic resonance imaging scans were performed on admission or shortly thereafter. The most common finding was cross-sectional involvement, in 16 patients (70%). The mean number of involved spinal segments was 8. The most frequently involved region was the thoracic spine, in 17 patients (74%). Clinical factors predicting good prognosis were cerebrospinal fluid pleocytosis, absence of tetraparesis, and prolonged time to nadir. In conclusion, most children with acute transverse myelitis appear to have a good outcome. Prompt diagnosis and treatment are important. Further research is needed in a larger sample to evaluate the predictive value of imaging features.

Abstract Background: The authors report serial magnetic resonance imaging findings of osmotic demyelination syndrome (ODS) related to hyperglycemia in a patient with uncontrolled diabetes mellitus. Case presentation: A 61-year-old man with diabetes was admitted for general weakness and severe thirst. A few days later, he complained of dysarthria, dysphasia, and dysmetria. On admission, he exhibited significant hyperglycemia (33.5 mmol/L [627 mg/dL]), with a glycated hemoglobin level of 18.1%. Other laboratory investigations revealed a sodium level of 133 mEq/L, potassium 3.8 mEq/L, blood urea nitrogen 43.9 mg/dL, with a calculated serum osmolality of 324 mOsm/kg. Brain magnetic resonance imaging (MRI) revealed T2 signal abnormalities that were symmetrical, non-space occupying, and located in the central pons with a peripheral sparing pattern, which were findings suggestive of ODS. In addition, subsequent MRI revealed progression of signal hyperintensity; however, the patient's symptoms were improved and he was discharged after 2 months. Conclusion: We report a rare case of hyperglycemia-related ODS that exhibited gradual progression in imaging features despite the prompt correction of blood sugar levels and improvement of neurological symptoms

Pol III-related leukodystrophy is a recently recognized category of leukodystrophy with characteristic clinical presentation and imaging findings. These cases are diagnosed by the combination of typical clinical presentation, brain magnetic resonance imaging findings, and the presence of biallelic pathogenic mutations in three specific genes. We present the case of a 6-year-old girl who demonstrated the classic clinical and imaging features of this disorder. This case report aims to raise awareness of this disorder so that it is easily recognized in the appropriate setting.
