“…This hypothesis is consistent with the fact that both the vessels and nerves go through the lipomas instead of getting displaced by them (9,14). controversial in such cases of asymptomatic lesions; moreover the risks of surgery can outweigh the potential benefits (13,18). PCL has been described to have two morphological types: tubulonodular and curvilinear (9,(16)(17)(18).…”

AIM: To determine the clinical and radiographical aspects of six patients diagnosed with pericallosal lipomas (PCL). MATERIAL and METHODS: A retrospective analysis of patients who presented to the neurosurgery outpatient clinics of Selcuk Faculty of Medicine between 2009 and 2019, revealed that six patients were diagnosed with PCL. The clinical and magnetic resonance imaging (MRI) data were obtained by reviewing patients' records. RESULTS: A total of six patients (two girls and four boys), with a mean age of 53.8 months (38-72 months), were included in this study. They were followed up for a mean period of 36.5 months (32-41 months). PCL were detected on MRIs, which were obtained to investigate headache in two patients, epilepsy in one patient, frontal dermal sinus tract and left frontal epidermoid tumor in one patient, and subcutaneous lipoma associated with PCL in one patient. Five patients displayed tubulonodular lipomas and one patient displayed curvilinear lipomas. Agenesis or dysgenesis of the corpus callosum (CC) was observed in four (66%) patients. Two patients received surgical treatment for cosmetic skin problem. CONCLUSION: Because of the benign course of PCL, i.e. no growth or very slow growth, and close proximity to the surrounding neurovascular structures, surgical removal should be considered only in symptomatic PCL. Furthermore, other malformations and anomalies may accompany PCL.

“…Intracranial lipomas can be tubulonodular or curvilinear in shape ( 24 ), and they are often associated with midline anomalies, the most frequent of which is agenesia/dysplasia of the corpus callosum (up to 50% in some case studies) ( 25 ). Our patient did show a curvilinear lipoma in the suprasellar cistern, close to the tuber cinereum and contiguous to the posterior pituitary gland, without any midline deformities.…”

Case Report: Lipoma of the Tuber Cinereum Mimicking a Pituitary Gland Abnormality in a Girl With Central Precocious Puberty

IntroductionMagnetic Resonance Imaging (MRI) is the best approach to investigate the hypothalamic-pituitary region in children with central precocious puberty (CPP). Routine scanning is controversial in girls aged 6-8 year, due to the overwhelming prevalence of idiopathic forms and unrelated incidentalomas. Cerebral lipomas are rare and accidental findings, not usually expected in CPP. We report a girl with CPP and an unusually shaped posterior pituitary gland on SE-T1w sequences.Case DescriptionA 7.3-year-old female was referred for breast development started at age 7. Her past medical history and physical examination were unremarkable, apart from the Tanner stage 2 breast. X-ray of the left-hand revealed a bone age 2-years ahead of her chronological age, projecting her adult height prognosis below the mid parental height. LHRH test and pelvic ultrasound were suggestive for CPP. Routine brain MRI sequences, SE T1w and TSE T2w, showed the posterior pituitary bright spot increased in size and stretched upward. The finding was considered as an anatomical variant, in an otherwise normal brain imaging. Patient was started on treatment with GnRH analogue. At a thorough revaluation, imaging overlap with adipose tissue was suspected and a new MRI scan with 3D-fat-suppression T1w-VIBE sequences demonstrated a lipoma of the tuber cinereum, bordering a perfectly normal neurohypophysis. 3D-T2w-SPACE sequences, acquired at first MRI scan, would have provided a more correct interpretation if rightly considered.ConclusionThis is the first evidence, to our knowledge, of a cerebral lipoma mimicking pituitary gland abnormalities. Our experience highlights the importance of considering suprasellar lipomas in the MRI investigation of children with CPP, despite their rarity, should the T1w sequences show an unexpected pituitary shape. 3D-T2w SPACE sequences could be integrated into standard ones, especially when performing MRI routinely, to avoid potential misinterpretations.
